Introduction

Maxtor Corporation

Maxtor Corporation has been providing high-quality computer storage products since 1982. Along the way, we’ve seen many changes in data storage needs. Not long ago, only a handful of specific users needed more than a couple hundred megabytes of storage. Today, downloading from the Internet and CD-ROMs, multimedia, networking and advanced office applications are driving storage needs even higher. Even home PC applications need capacities measured in gigabytes, not megabytes.

Products

Maxtor’s products meet those demanding storage capacity requirements with room to spare. They feature proven compatibility and reliability. While DiamondMax™ Plus 5120 is the latest addition to our family of high performance 7,200 RPM desktop hard drives, the 5,400 RPM DiamondMax™ 4320 series hard drives deliver industry-leading capacity, performance and value for many PC applications.

Support

No matter which capacity, all Maxtor hard drives are supported by our commitment to total customer satisfaction and our No Quibble (http://www.maxtor.com) – puts you in touch with either technical support or customer service. We’ll provide you the information you need quickly, accurately and in the form you prefer – a fax, a downloaded file or a conversation with a representative.

DIAMONDMAX PLUS 5120 – INTRODUCTION

Conventions

If there is a conflict between text and tables, the table shall be accepted as being correct.

Key Words

The names of abbreviations, commands, fields and acronyms used as signal names are in all uppercase type (e.g., IDENTIFY DRIVE). Fields containing only one bit are usually referred to as the “name” bit instead of the “name” field.

Names of drive registers begin with a capital letter (e.g., Cylinder High register).

Numbering

Numbers that are not followed by a lowercase “b” or “h” are decimal values. Numbers that are followed by a lowercase “b” (e.g., 01b) are binary values. Numbers that are followed by a lowercase “h” (e.g., 3Ah) are hexadecimal values.

Signal Conventions

Signal names are shown in all uppercase type.

All signals are either high active or low active signals. A dash character (-) at the end of a signal name indicates that the signal is low active. A low active signal is true when it is below ViL and is false when it is above ViH. A signal without a dash at the end indicates that the signal is high active. A high active signal is true when it is above ViH and is false when it is below ViL.

When a signal is asserted, it means the signal is driven by an active circuit to its true state.

When a signal is negated, it means the signal is driven by an active circuit to its false state.

When a signal is released, it means the signal is not actively driven to any state. Some signals have bias circuitry that pull the signal to either a true or false state when no signal driver is actively asserting or negating the signal. These instances are noted under the description of the signal.

PRODUCT DESCRIPTION

Product Features

Functional / Interface

Maxtor DiamondMax™ Plus 5120 hard drives contain all necessary mechanical and electronic parts to interpret control signals and commands from an AT-compatible host computer. See Section 3 Product Specifications, for complete drive specifications.

Zone Density Recording

The disk capacity is increased with bit density management – common with Zone Density Recording. Each disk surface is divided into 16 circumferential zones. All tracks within a given zone contain a constant number of data sectors. The number of data sectors per track varies in different zones; the outermost zone contains the largest number of data sectors and the innermost contains the fewest.

Read/Write Multiple Mode

This mode is implemented per ANSI ATA/ATAPI-4 specification. Read/Write Multiple allows the host to transfer a set number of sectors without an interrupt request between them, reducing transfer process overhead and improving host performance.

UltraDMA - Mode 2

Maxtor DiamondMax Plus 5120 hard drives fully comply with the new ANSI Ultra DMA protocol, which greatly improves overall AT interface performance by significantly improving burst and sustained data throughput.

Multi-word DMA (EISA Type B) - Mode 2

Supports multi-word Direct Memory Access (DMA) EISA Type B mode transfers.

Sector Address Translation

All DiamondMax Plus 5120 drives feature a universal translate mode. In an AT/EISA-class system, the drive may be configured to any specified combination of cylinders, heads and sectors (within the range of the drive's formatted capacity). DiamondMax Plus 5120 drives power-up in a translate mode:

LEDOMLYCDHTPSenoZLmocPWABLXAMYTICAPAC

(*) The fields LZone (Landing Zone) and WPcom (Write Pre-comp) are not used by the Maxtor hard drive and the values may be either 0 or the values set by the BIOS. All capacities listed in the above table are based on 106 or one million bytes.

2 – 2

PRODUCT DESCRIPTION

Logical Block Addressing

The Logical Block Address (LBA) mode can only be utilized in systems that support this form of translation. The cylinder, head and sector geometry of the drive, as presented to the host, differs from the actual physical geometry. The host AT computer may access a drive of set parameters: number of cylinders, heads and sectors per track, plus cylinder, head and sector addresses. However, the drive can’t use these host parameters directly because of zoned recording techniques. The drive translates the host parameters to a set of logical internal addresses for data access.

The host drive geometry parameters are mapped into an LBA based on this formula:

LBA = (HSCA - 1) + HHDA x HSPT + HNHD x HSPT x HCYA (1)

where HSCA = Host Sector Address, HHDA = Host Head Address

= (HSCA - 1) + HSPT x (HHDA + HNHD x HCYA) (2)

HCYA = Host Cylinder Address, HNHD = Host Number of Heads HSPT = Host Sectors per Track

The LBA is checked for violating the drive capacity. If it does not, the LBA is converted to physical drive cylinder, head and sector values. The physical address is then used to access or store the data on the disk and for other drive related operations.

Defect Management Zone (DMZ)

Each drive model has a fixed number of spare sectors per drive, all of which are located at the end of the drive. Upon detection of a bad sector that has been reassigned, the next sequential sector is used.

For example, if sector 3 is flagged, data that would have been stored there is “pushed down” and recorded in sector 4. Sector 4 then effectively becomes sector 3, as sequential sectors are “pushed down” across the entire drive. The first spare sector makes up for the loss of sector 3, and so maintains the sequential order of data. This push down method assures maximum performance.

On-the-Fly Hardware Error Correction Code (ECC)

5 symbols, single burst, guaranteed

Software ECC Correction

22 symbols, single burst, guaranteed

Automatic Park and Lock Operation

Immediately following power down, dynamic braking of the spinning disks delays momentarily allowing the read/write heads to move to an inner mechanical stop. A small fixed magnet holds the rotary actuator in place as the disk spins down. The rotary actuator is released only when power is again applied.

PRODUCT DESCRIPTION

Cache Management

Buffer Segmentation

The data buffer is organized into two segments: the data buffer and the micro controller scratch pad. The data buffer is dynamically allocated for read and write data depending on the commands received. A variable number of read and write buffers may exist at the same time.

Read-Ahead Mode

Normally, this mode is active. Following a read request, disk read-ahead begins on the first sector and continues sequentially until the allocated buffer is full. If a read request is received during the read-ahead operation, the buffer is examined to determine if the request is in the cache. If a cache hit occurs, readahead mode continues without interruption and the host transfer begins immediately.

Automatic Write Reallocation (AWR)

This feature is part of the write cache and reduces the risk of data loss during deferred write operations. If a disk error occurs during the disk write process, the disk task stops and the suspect sector is reallocated to a pool of alternate sectors located at the end of the drive. Following reallocation, the disk write task continues until it is complete.

Write Cache Stacking

Normally, this mode is active. Write cache mode accepts the host write data into the buffer until the buffer is full or the host transfer is complete. A command complete interrupt is generated at the end of the transfer.

A disk write task begins to store the host data to disk. Host write commands continue to be accepted and data transferred to the buffer until either the write command stack is full or the data buffer is full. The drive may reorder write commands to optimize drive throughput.

PRODUCT DESCRIPTION

Major HDA Components

Drive Mechanism

A brush-less DC direct drive motor rotates the spindle at 7,200 RPM (±0.1%). The dynamically balanced motor/spindle assembly ensures minimal mechanical run-out to the disks. A dynamic brake provides a fast stop to the spindle motor upon power removal. The speed tolerance includes motor performance and motor circuit tolerances.

Rotary Actuator

All DiamondMax™ Plus 5120 drives employ a rotary voice coil actuator which consists of a moving coil, an actuator arm assembly and stationary magnets. The actuator moves on a low-mass, low-friction center shaft. The low friction contributes to fast access times and low power consumption.

Read/Write Electronics

An integrated circuit mounted within the sealed head disk assembly (near the read/write heads) provides up to eight head selection (depending on the model), read pre-amplification and write drive circuitry.

Read/Write Heads and Media

Low mass, low force giant magneto-resistive read/write heads record data on 3.5-inch diameter disks. Maxtor uses a sputtered thin film medium on all disks for DiamondMax Plus 5120 drives.

Air Filtration System

All DiamondMax Plus 5120 drives are assembled in a Class 100 controlled environment. Over the life of the drive, a 0.1 micron filter and breather filter located within the sealed head disk assembly (HDA) maintain a clean environment to the heads and disks. DiamondMax Plus 5120 drives are designed to operate in a typical office environment with minimum environmental control.

Microprocessor

The microprocessor controls the following functions for the drive electronics:

Command execution Cache management Data correction and error recovery Diagnostic execution Data sequencing Head positioning (including error recovery) Host interface Index detection Spin speed control Seeks Servo S.M.A.R.T.

PRODUCT DESCRIPTION

Subsystem Configuration

Dual Drive Support

Two drives may be accessed via a common interface cable, using the same range of I/O addresses. The drives are jumpered as device 0 or 1 (Master/Slave), and are selected by the drive select bit in the Device/Head register of the task file.

All Task File registers are written in parallel to both drives. The interface processor on each drive decides whether a command written to it should be executed; this depends on the type of command and which drive is selected. Only the drive selected executes the command and activates the data bus in response to host I/O reads; the drive not selected remains inactive.

A master/slave relationship exists between the two drives: device 0 is the master and device 1 the slave. When J50 is closed (factory default, figure 2-1), the drive assumes the role of master; when open, the drive acts as a slave. In single drive configurations, J50 must be closed.

Cable Select Option

CSEL (cable select) is an optional feature per ANSI ATA specification. Drives configured in a multiple drive system are identified by CSEL’s value:

– If CSEL is grounded, then the drive address is 0. – If CSEL is open, then the drive address is 1.

Jumper Location/Configuration

Darkened jumper pins indicate factory-installed (default) shunts.

4092 Cylinder Limitation

On some older BIOS', primarily those that auto-configure the disk drive, a hang may occur when the drive cylinder value exceeds 4096. The 4092 Cylinder Limitation jumper reduces the capacity in the Identify Drive to 4092 allowing large capacity drives to work with older BIOS'. A software driver is required to access the full capacity of the drive.

EMC/EMI

Radiated Electromagnetic Field Emissions - EMC Compliance

The hard disk drive mechanism is designed as a subassembly for installation into a suitable enclosure and is therefore not subject to Subpart J of Part 15 of FCC Rules (47CFR15) or the Canadian Department of Communications Radio Interference Regulations. Although not required, the disk mechanism has been tested within a suitable end-use product and found to comply with Class B limits of the FCC Rules and Regulations of the Canadian Department of Communications.

The CE Marking indicates conformity with the European Union Low Voltage Directive (73/23/EEC) when the disk mechanism is installed in a typical personal computer. Maxtor recommends that testing and analysis for EMC compliance be performed with the disk mechanism installed within the user's end-use application.

Canadian Emissions Statement

This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian department of communications.

Le present appareil numerique n'emet pas de bruit radioelectriques depassant les limites applicables aux appareils numeriques de Class B prescrites dans le reglement sur le brouillage radioelectrique edicte par le ministere des communications du Canada.

INSTALLATION

Handling and Installation

Pre-formatted Drive

This Maxtor hard drive has been formatted at the factory. Do not use a low-level formatting program.

Important Notice

There are a number of system BIOS’s currently in use which do not support hard drives with more than 4095 cylinders (2.1 gigabytes). This section contains information describing the conditions which may identify this limitation. In order to obtain the full capacity of your Maxtor drive, you will need to follow the recommended installation instructions.

Hard Drive Handling Precautions

◆ During handling, NEVER drop, jar, or bump a drive. Handle the drive by its sides and avoid touching the printed circuit

board assembly (PCBA).

◆ Hard drives are sensitive to electrostatic discharge (ESD) damage. Use proper ESD practices by grounding yourself

and the computer system the hard drive will be installed in.

SECTION 4

◆ Allow the hard drive to reach room temperature BEFORE installing it in your computer system.

◆ NEVER switch DC power onto the drive by plugging an electrically live DC source cable into the drive's connector.

NEVER connect a live connector to the hard drive's IDE interface connector.

Electro-Static Discharge (ESD)

To avoid some of the problems associated with ESD, Maxtor advises that anyone handling a disk drive use a wrist strap with an attached wire connected to an earth ground. Failure to observe these precautions voids the product warranty.

Manufacturers frequently experience “unsolved” component/hardware malfunctions often caused by ESD. To reduce the incidence of ESD-related problems, Maxtor recommends that any electronics manufacturing plans include a comprehensive ESD program, the basic elements and functions of which are outlined here:

ESD Program Element ESD Program Function Management Institute and maintain Chief coordinator Organize and enforce Multi-department committee Evaluate and improve Employee training Educate and inform

ESD program supplies typically include: wrist- and foot-worn grounding straps; counter-top and floor antistatic matting; wrist strap testers; ESD video and training materials. Sources for such supplies include:

Static Control Systems – 3M Charleswater 225-4S, 3M Center 93 Border St. St. Paul, MN 55144 West Newton, MA 02165-9990

Maxtor also offers a complete video training package, “Care and Handling of Maxtor Disk Drives.” Contact your Maxtor representative for details.

Capacity Barriers

Due to operating system limitations, DOS cannot access the full capacity of drives larger than 8.4 GB. The Microsoft Windows 95 operating system or equivalent (full installation), NOT a Windows 95 upgrade from DOS (Windows 3.1 or 3.11), is required to obtain the full capacity of any hard drive larger than 8.4 GB.

Protecting Your Existing Data

Periodic backup of important data is always a good idea. Whenever your computer is on, there is the potential for losing data on your hard drive. This is especially true when running disk utilities or any software that directly manipulates your files. Maxtor recommends that you data may then be copied to the Maxtor hard drive after it has been installed in your computer. Refer to your computer user’s manual for detailed data backup instructions.

General Requirements

System Hardware Requirements

The minimum system Maxtor recommends for drives 8.4 GB or less is a 486 DX 66 MHz system. For drives larger than 8.4 GB, we recommend a Pentium-class system.

BIOS Requirements

System BIOS dated prior to September 1997 do not support drives greater than 8.4 GB. To obtain the full capacity of a drive larger than 8.4 GB, upgrade the BIOS, install a BIOS enhancer card or use the MaxBlast installation software (version 9.06 or newer).

Ultra Direct Memory Access (UDMA)

UDMA mode on a Maxtor hard drive will only activate when the drive is installed in a system with full UDMA capability, i.e., a mother board or interface card with the UDMA chips and the associated UDMA software drivers.

OS Requirements for Large Capacity Hard Drives

A full installation of the Windows 95 operating system is required for hard drives larger than 8.4 GB when the drive is a Primary Master. An upgrade to Windows 95 from Windows 3.11 and/or the DOS operating system will not support drive capacities greater than 8.4 GB when the drive is a Primary Master.

IDE stands for Integrated Drive Electronics and EIDE is Enhanced IDE. The IDE or EIDE interface is designed to support two devices – typically hard drives – on a single ribbon cable through one 40 pin connector on the mother board or interface card.

Some mother boards and interface cards may have a second IDE/EIDE connector to support two additional IDE devices. The IDE/EIDE interface is identified as a primary or secondary interface. In systems with only a single connector on the mother board or interface card, it is the primary IDE/EIDE interface. To add a second IDE/EIDE interface requires a special interface card. In systems with two connectors on the mother board or interface card, one is the primary and the other as the secondary.

Hard Drive Identification

The primary interface must be used for at least one IDE device before connecting any devices to the secondary IDE interface.

Ribbon cable lengths are limited to 18 inches and have two or three 40 pin connectors. This cable is referred to as a parallel cable and IDE devices may be connected anywhere on the cable. One of the connectors is attached to the IDE connector on the mother board or interface card and the remaining connector(s) are available for the IDE devices.

Identifying IDE Devices on the Interface

Each device must be identified as either the Master or Slave device on that interface (cable). Each cable must have a Master before it can have a Slave device on the cable. There cannot be two Master or two Slave devices on the same cable.

IDE devices use jumpers to designate the Master/Slave identification of the device. Each manufacturer may have its own jumpering scheme to identify the device as a Master or Slave and its relationship to other IDE devices attached to the same cable.

Jumper Settings

A jumper is a small piece of plastic that slides over a pair of configuration pins on the drive to activate a specific function. The jumper illustration below shows three valid jumper settings for Maxtor hard drives – Master, Slave and Cable Select. Maxtor hard drives can be set as either a Master or a Slave device. There are no other jumpers to set when the Maxtor drive is installed on the same ribbon cable with another IDE device.

4 – 16

Rear View of Maxtor Hard Drive

Master, Slave and Cable Select Settings

INSTALLATION

Before installing the drive in the computer, you must determine how the jumpers on the Maxtor hard drive are to be set for your system based upon the use of the Maxtor hard drive as either a Master or Slave device. Maxtor hard drives are shipped with the Master jumper setting enabled.

IMPORTANT: If a Maxtor hard drive is being added to a system on the same cable with an existing IDE device, it may be necessary to re-configure the jumpers on the existing device to insure that the system will properly recognize both devices. Information regarding the correct jumper configurations on other IDE devices is available in their product documentation or from the manufacturer of that device.

Systems Using Cable Select

IMPORTANT – Most systems do not use this feature. Unless you are sure that your computer system supports Cable Select, do not set up the drive with this feature enabled.

Maxtor hard drives support Cable Select. The Cable Select method of drive identification allows the system to identify Master and Slave IDE devices based upon the position (connector) the IDE device is attached to on the interface (ribbon) cable.

A special IDE cable select interface (ribbon) cable is required for systems using the Cable Select feature.

Systems that use Cable Select do not support the standard Master/Slave definitions described above and the standard IDE interface (ribbon) cable cannot be used on these systems. If your system supports this feature, refer to the system user’s manual or contact the system manufacturer for specific procedures for installing hard drives.

On Maxtor hard drives, Cable Select is enabled by installing a jumper on J48.

Relationship to Other IDE Devices

Maxtor recommends that its hard drives be configured as a Master device to any IDE device that is not a hard drive (e.g., CD-ROM’s, Tape drives, Zip Drives etc.).

Turn the computer OFF, disconnect the power cord and remove the cover. Refer to the computer user’s manual for information on removing the cover.

Each system manufacturer uses different types of cases, including desktop, mini-tower, full tower and other special configurations. As a result, there are many different possible mounting locations that could be used.

In a typical system case, there are specific 3.5 inch and 5.25 inch bays available for storage devices. When a 3.5 inch mounting bay is available, mounting brackets are not required. If a 5.25 inch mounting bay is used, mounting brackets will be required to mount the Maxtor hard drive in the system case. Refer to the system manufacturers user’s manual or contact the system manufacturer directly for additional information.

Mounting Drive in System

Installing 5.25-inch Mounting Brackets and Rails

If the Maxtor hard drive is being mounted in a 5.25 inch drive bay, the following figure shows how to attach the brackets to the drive. The brackets are not required when mounting in a 3.5 inch drive bay.

Installing in a Device Bay

After the hard drive is prepared with mounting brackets, if required, and the jumpers are set correctly, the drive can be mounted in a device bay and secured. Be sure to secure the drive with all four screws in the device bay. This provides grounding and protection from shock and vibration.

NOTE: Computer systems use different methods for mounting hard drives. Please refer to the computer user’s manual or contact the manufacturer for specific mounting instructions.

4 – 17

INSTALLATION

In order for the computer to recognize that the Maxtor hard drive is in the system, the power cable and IDE interface cable must be properly connected.

1 Attach an available IDE interface connector to J1 on the Maxtor hard drive.

2 Connect an available power connector to J2 on the Maxtor hard drive. This connector is keyed and will only fit in one orientation.

and Power Cables

The striped or colored edge of the IDE interface cable indicates pin 1. Pin 1 on the IDE interface cable connector must match pin 1 on the Maxtor hard drive IDE interface connector – closest to the drive power connector. It must also match pin 1 on the IDE connector on the mother board or IDE interface card. Refer to the system or interface card user’s manual for identification of pin 1 on their IDE interface connector.

Do not force the connector.

After attaching the IDE

interface cable and the

power cable to the Maxtor

hard drive, verify that all

other cables connected to

other devices, the mother

board or interface card(s) are

correctly seated.

Attaching Interface

Striped/colored edge is pin

The computer system the Maxtor hard drive is being installed in will have its own cable placement and connection methods. This means that the location of the IDE interface connectors on the mother board and/or interface card and the orientation of pin one is determined by the manufacturer. Also, older systems and interface cards may have only a single IDE interface connection – limiting the system to two IDE devices. Refer to the system or interface card user’s manual for cable connection and orientation instructions.

Attach the 40-pin IDE interface cable from the Maxtor hard drive to the IDE connector on the mother board or IDE interface card. Insure that the red edge of the ribbon cable is oriented to pin 1 on the interface.

INSTALLATION

The following procedures are designed for systems using the DOS 5.0 (or higher), Windows 95 and Windows 98 operating systems. For other operating systems (e.g., Windows NT, OS2, UNIX, LINUX and Novell requirements.

For drives with capacities larger than 8.4 GB, the full installation set for Windows 95A or 95B (OSR2), Windows 98 or equivalent, is required. Operating systems that do not support extended interrupt 13 cannot access or format a drive larger than 8.4 GB. This is true regardless of BIOS, mother board or interface card support. DOS based operating systems do not support this interrupt and are limited to a maximum drive size that they can format and access of 8.4 GB. It is not possible to upgrade from a DOS operating system to Windows 95 and obtain the full capacity of a drive larger than 8.4 GB.

System Setup

NetWare), refer to the operating system user’s manual for the BIOS setting and other installation

Setting the BIOS (CMOS)

The SETUP (BIOS) program identifies the system configuration information (e.g., floppy disk drives, hard disk drives, video, etc.) used to identify devices attached to the computer during system boot. This includes the information about what kind and how many IDE hard drives are attached to the system.

IMPORTANT: Please Note – Major BIOS manufacturers like AMI, Award and Phoenix provide their core BIOS programs to system board manufacturers and OEM’s who have the capability of making modifications to some of the descriptions and definitions to meet their unique requirements. These changes include, but are not limited to, how to access the BIOS, the appearance of the information on the screens and the location of parameters within the BIOS. Refer to the system or BIOS manufacturers documentation or contact the system manufacturer for the correct procedure to enter the BIOS setup program for your computer. Some manufacturers may use their own unique BIOS definitions and configurations and will also have their own methods for accessing and setting the BIOS. If you have a system that uses such a unique BIOS, refer to the system user’s manual or contact the manufacturer for assistance.

WARNING: When entering settings for the Maxtor hard drive, be careful not to change any of the other BIOS settings, or other parts of the system may not work correctly.

BIOS (CMOS) Parameters

In order for the computer system to recognize the new Maxtor hard drive, it is necessary to set the system BIOS with the correct information about the drive. To do this, run the system SETUP (BIOS) program.

The Maxtor hard drive must be identified to the system through the BIOS and it must be registered in the BIOS based upon its position relative to the other IDE devices connected to the system and recorded in the BIOS.

Most newer BIOS’ provide the descriptions of Primary Master, Primary Slave, Secondary Master and Secondary Slave (see section 2) which identify the device configuration and location on an IDE interface and its relationship to the other IDE devices on the same interface or ribbon cable.

Some older BIOS versions do not use this terminology for identification and it may be necessary to refer to the system user’s manual or BIOS documentation to determine where the drive settings should be set in that specific BIOS. If this information is not available, then it will be necessary to contact the system manufacturer for the correct terminology to correctly identify the drives within the system.

The following are the typical steps to be used to set the hard drive parameters in a BIOS:

A Turn the system ON. During the system start-up sequence, run the SETUP (BIOS) program or similar commands to access the system BIOS.

Note: Newer systems will typically display a message (e.g., press DEL to Enter Setup) identifying how to access the SETUP (BIOS) program.

B Once the SETUP (BIOS) program is active, do one of the following to set the BIOS parameters for the Maxtor hard drive.

1 Enter the BIOS menu where the hard drive settings are displayed, select the correct entry (Primary Master, Primary Slave, Secondary Master or

Secondary Slave or their equivalents) to set the parameters for the Maxtor hard drive.

If the SETUP program provides an “AUTO DETECT” capability, use this feature to detect the Maxtor hard drive. If the SETUP program does not have AUTO DETECT, set the drive parameters as defined in step 2. Typically, this feature is available for each individual IDE device. It may be necessary to exit the BIOS, re-boot the system and re-enter the BIOS before the AUTO DETECT operation will take effect.

IMPORTANT After the SETUP program has detected the hard drive, verify that the Logical Block Addressing (LBA) mode is enabled for the drive - as not all BIOS versions set this feature during the AUTO DETECT process.

Comment: When LBA is enabled, some BIOS programs (typically Award) will change the values of the cylinders and heads by dividing the cylinders by 2, 4, 8 or 16 and multiplying the heads by the same value. This operation will not change the capacity of the hard drive.

If the system correctly detects the drive and does not hang during the boot process, proceed to Section 8. If the system hangs during the POST, proceed to Section 9. If Auto Detect did not find the drive and no error message was presented, proceed to step 2 below.

2 Enter the BIOS menu where the hard drive definitions are displayed and select the appropriate entry (Primary Master, Primary Slave, Secondary

Master or Secondary Slave – or their equivalents) for the Maxtor hard drive. If the SETUP program does not provide an AUTO DETECT capability, the drive parameters must be set using the User Definable Type (UDT).

4 – 19

INSTALLATION

Set the Cylinder, Head and Sector values with the values listed on the drive label. The drive label is located on the top cover of the drive. The fields LZone (Landing Zone) and WPcom (Write Pre-comp) are not used by the Maxtor hard drive. These fields may be set to 0 or by the values assigned by the BIOS.

Note: Each BIOS manufacturer uses different methods of identifying the UDT. Newer BIOS’ from all manufacturer’s will usually include an entry called “User” or “User 1.” Older BIOS’ vary in the method used to identify the UDT. Following are examples of BIOS UDT: AMI = Type 47, Award = Type 47 and Phoenix = Type 48

Only the cylinder, head and sector values printed on the drive label must be entered. All other values may be zero (0). Set the LBA mode to enabled for this drive. Refer to the system user’s manual or contact the system manufacturer for information on enabling LBA.

If the SETUP program does not provide the UDT, set the BIOS to the drive type with the largest capacity of those listed in the BIOS.

C After the drive parameters are entered, follow the SETUP program procedures to save the settings and exit the SETUP program. After changing BIOS

settings, saving the values and exiting, the SETUP program should force the system to re-boot.

If you are not sure how the UDT is defined in the BIOS, refer to the computer user’s manual or contact the system manufacturer.

To finish the installation, the drive must be partitioned and formatted. Hard drive partitioning and formatting may be done with the operating system software or with MaxBlast installation software. Select A or B below to complete the preparation of the Maxtor hard drive.

NOTE: Drive letter assignment is controlled by the operating system and not by the BIOS or MaxBlast. The operating system assigns drive letters to all devices as follows: (1) to all hard drives and their partitions; (2) to all other devices like CD-ROM’s and tape drives. When adding an additional hard drive to the system, the drive letters will be automatically changed by the operating system.

A Preparing the hard drive using the operating system software.

IMPORTANT Due to operating system limitations, DOS operating systems cannot access the full capacity of drives larger than 8.4 GB. The Windows 95 full

installation, not an upgrade from DOS, operating system or equivalent is required to obtain the full capacity of any drive larger than 8.4 GB.

If the system or interface card correctly supports the Maxtor hard drive, the drive may be partitioned and formatted using the operating system software. If the cylinder limitation jumper (J46) is installed or the BIOS does not support the hard drive, the MaxBlast installation software (option B below) must be used to prepare the hard drive.

NOTE: All versions of DOS, PC-DOS, DR-DOS and Windows 95A (FAT 16 support) have a partition size limitation of 2.1 GB. For drives larger than 2.1 GB, the drive must be divided into partitions that do not exceed the 2.1 GB limitation. Windows 95B (OSR2) does not have this limitation. Windows NT, OS2, UNIX, LINUX and Novell NetWare may have different limitations but please refer to their documentation or contact the manufacturer to verify their support or limitations.

For detailed operating system installation assistance, refer to the system manufacturers user’s manual, the operating system user’s manual or contact the manufacturer directly.

B Preparing the hard drive using MaxBlast installation software.

Hard Drive Preparation

1 Boot the system with the bootable MaxBlast software installation diskette.

2 The MaxBlast installation software will load and the first screen of the program will display. Follow the on-screen prompts to complete the hard drive

installation.

4 – 20

INSTALLATION

System Hangs During Boot

If the system hangs during the boot process after installing the Maxtor hard drive – either before or after setting the system BIOS – the system many have a BIOS with a cylinder limitation. This may occur for hard drives that exceed 2.1 GB. If this happens, do the following:

1 Turn the system OFF.

2 Install the cylinder limitation jumper (J46) on the drive. The figure below shows the Maxtor hard drive configured as a Master or Slave device with the

cylinder limitation jumper installed.

IMPORTANT: When the Cylinder Limitation jumper (J46) is installed, the Maxtor hard drive must be prepared using MaxBlast installation software.

3 If the BIOS was set to AUTO DETECT, follow the instructions in Section 7 to prepare the hard drive using the MaxBlast installation software.

If other BIOS settings were used, access the system BIOS SETUP program and set the parameters to a User Definable Type with 4,092 cylinders, 16 heads and 63 sectors per track for the Maxtor hard drive. Then follow the instructions for setting the BIOS in Section 7 then Section 8 to prepare the hard drive with MaxBlast software.

HOST SOFTWARE INTERFACE

1F7h Status Register Command Register

SECTION 6

Host Software Interface

The host communicates with the drive through a set of controller registers accessed via the host’s I/O ports. These registers divide into two groups: the Task File, used for passing commands and command parameters and the Control/Diagnostic registers.

Task File Registers

The Task File consists of eight registers used to control fixed disk operations. The host accesses each register by the I/O port address shown in this Task File register map:

I/O PORT READ WRITE

1F0h Data Register Data Register 1F1h Error Register Features Register 1F2h Sector Count Sector Count 1F3h Sector Number Sector Number 1F4h Cylinder Low Cylinder Low 1F5h Cylinder High Cylinder High 1F6h Drive/Head (SDH) Drive/Head (SDH)

Data Register

Provides access to the drive’s sector buffer for read and write operations. With the exception of ECC byte transfers (which, during Read long and Write long commands, are 8 bits wide), data transfers through the Data register are all 16 bits wide.

Error Register

A read-only register containing specific information regarding the previous command. Data interpretation differs depending on whether the controller is in operational or diagnostic mode. A power up, reset, software reset, or receipt of a diagnostic command sets the controller into diagnostic mode. This mode invalidates contents of the Status register. The contents of the Error register reflect a completion code.

Issuing any command (apart from a Diagnostic command) places the controller into operational mode. In operational mode, the Error register is valid only when the Error bit in the Status register is set. The bit definitions for operational mode follow:

7 6 5 4 3 2 1 0

0 ECC 0 IDNF 0 ABRT TK0 AMNF

Interface

CRC

Interface CRC – An interface CRC error occurred during an Ultra DMA transfer.

Data ECC Error – An non-correctable ECC error occurred during a Read Sector command.

Firmware Problem – Indicates a firmware problem was detected, (e.g., invalid interrupt, divide overflow).

ID Not Found – Either a matching ID field not found, or a CRC error occurred.

Aborted Command – Invalid commands, write fault, no seek complete, or drive not ready.

Track 0 Error – Track 0 was not found during execution of a Restore command.

Address Mark Not Found – The Address Mark could not be found after an ID match.

Sector Count Register

Holds the number of sectors to be sent during a Read or Write command, and the number of sectors per track during a Format command. A value of zero in this register implies a transfer of 256 sectors. A multisector operation decrements the Sector Count register. If an error occurs during such an operation, this register contains the remaining number of sectors to be transferred.

Sector Number Register

Holds the starting sector number for any disk operation. The register is updated as each sector is processed in a multi-sector operation.

Cylinder Number Registers

Two 8-bit Cylinder Number registers (Low and High) specify the starting cylinder for disk operation.

Device/Head Register

Used to specify the drive and head number to be operated on during any disk operations. Within the context of a Set Parameters command, this register specifies the maximum number of heads on the drive. Bit definitions follow:

Status Register

Contains results of the last command executed, and the drive’s status. The other seven Task File registers may be read only when bit 7 (BUSY) of the Status register is low. Reading any of the Task File registers when BUSY is high returns the value of the Status register. Reading the Status register also clears any interrupt request to the host. Bit definitions follow:

Controller

Controller Busy – Goes active when a command is written to the Command register, indicating controller task execution. After a command, this bit resets.

Device Ready – Indicates that the drive is ready for commands. If drive ready is not present, all commands abort.

Device Fault – Indicates the drive’s detection of a write fault condition, causing all commands to abort.

Device Seek Complete – Signifies a seek completion, and that the drive is on track.

Data Request – Indicates that the drive’s sector buffer is ready for data transfer.

Error – The Error bit sets when the previous command has completed with a non-recoverable error.

HOST SOFTWARE INTERFACE

Reset and Interrupt Handling

Reset Handling

One of three different conditions may cause a reset: power on, hardware reset or software reset. All three cause the interface processor to initialize itself and the Task File registers of the interface. A reset also causes a set of the Busy bit in the Status register. The Busy bit does not clear until the reset clears and the drive completes initialization. Completion of a reset operation does not generate a host interrupt.

Task File registers are initialized as follows:

Error 1 Sector Count 1 Sector Number 1 Cylinder Low 0 Cylinder High 0 Drive/Head 0

Interrupt Handling

The drive requests data transfers to and from the host by asserting its IRQ 14 signal. This signal interrupts the host if enabled by bit 1 (IRQ enable) of the Fixed Disk Control register.

Clear this interrupt by reading the Status register, writing the Command register, or by executing a host hardware or software reset.

INTERFACE COMMANDS

Read Commands

Read Sector(s)

Reads from 1 to 256 sectors, as specified in the Command Block, beginning at the specified sector. (A sector count of 0 requests 256 sectors.) Immediately after the Command register is written, the drive sets the BSY bit and begins execution of the command. If the drive is not already on the desired track, an implied seek is performed.

Once at the desired track, the drive searches for the data address mark of the requested sector. The data address mark must be recognized within a specified number of bytes, or the Data Address Mark Not Found error will be reported. Assuming the data address mark is found:

1. The data field is read into the sector buffer.

2. Error bits are set (if an error was encountered).

3. The DRQ bit is set.

4. An interrupt is generated.

The DRQ bit is always set, regardless of the presence or absence of an error condition after the sector. Upon command completion, the Command Block registers contain the numbers of the cylinder, head and sector of the last sector read. Back-to-back sector read commands set DRQ and generate an interrupt when the sector buffer is filled at the completion of each sector. The drive is then ready for the data to be read by the host. DRQ is reset and BSY is set immediately when the host empties the sector buffer.

If an error occurs during Read Sector commands, the read terminates at the sector where the error occurred. The host may then read the Command Block to determine the nature of that error, and the sector where it happened. If the error type is a correctable or an non-correctable data error, the flawed data is loaded into the sector buffer.

A Read Long command sets the Long bit in the command code and returns the data and the ECC bytes in the data field of the specified sector. During a Read Long, the drive does not check the ECC bytes to determine if there has been a data error. The Read Long command is limited to single sector requests.

Read Verify Sector(s)

Identical to the Read Sector(s) command, except that:

1. DRQ is never set,

2. No data is transferred back to the host and

3. The long bit is not valid.

7 – 2

INTERFACE COMMANDS

Read DMA

Multi-word DMA

Identical to the Read Sector(s) command, except that

1. The host initializes a slave-DMA channel prior to issuing the command,

2. Data transfers are qualified by DMARQ and are performed by the slave-DMA channel and

3. The drive issues only one interrupt per command to indicate that data transfer has terminated and status is available.

Ultra DMA

With the Ultra DMA Read protocol, the control signal (DSTROBE) that latches data from DD(15:0) is generated by the devices which drives the data onto the bus. Ownership of DD(15:0) and this data strobe signal are given DSTROBE to the drive during an Ultra DMA data in burst.

During an Ultra DMA Read burst, the drive always moves data onto the bus, and, after a sufficient time to allow for propagation delay, cable settling, and setup time, the sender shall generate a DSTROBE edge to latch the data. Both edges of DSTROBE are used for data transfers.

Any unrecoverable error encountered during execution of a Read DMA command terminates data transfer after the transfer of all sectors prior to the sector where the error was detected. The sector in error is not transferred. The drive generates an interrupt to indicate that data transfer has terminated and status is available. The error posting is identical to the Read Sector(s) command.

Read Multiple

Performs similarly to the Read Sector(s) command, except that for each READ MULTIPLE command data transfers are multiple sector blocks and the Long bit is not valid.

Execution is also similar to that of the READ SECTOR(S) command, except that:

1. Several sectors are transferred to the host as a block, without intervening interrupts.

2. DRQ qualification of the transfer is required only at the start of each block, not of each sector.

The block count consists of the number of sectors to be transferred as a block. (The block count is programmed by the Set Multiple Mode command, which must be executed prior to the Read Multiple command.) READ LONG command is limited to single sector requests.

When the Read Multiple command is issued, the Sector Count register contains the number of sectors requested — not the number of blocks or the block count. If the number of sectors is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. This final, partial block transfer is for N sectors, where N = (sector count) modulo (block count)

The Read Multiple operation will be rejected with an Aborted Command error if attempted:

1. Before the Set Multiple Mode command has been executed, or

2. When Read Multiple commands are disabled.

The controller reports disk errors encountered during Read Multiple commands at the start of the block or partial block transfer. However, DRQ still sets, and the transfer occurs normally, along with the transfer of any corrupt data. Remaining block data from the following the sector in error is not valid.

If the Sector Count register contains 0 when the Set Multiple Mode command is issued, Read Multiple and Write Multiple commands are disabled; no error is returned. Once the appropriate action has been taken, the controller resets BSY and generates an interrupt. At power up, or after a hardware or software reset, Read Multiple and Write Multiple commands are disabled by default.

7 – 3

INTERFACE COMMANDS

Set Multiple Mode

Enables the controller to perform Read and Write Multiple operations, and establishes the block count for these commands. Before issuing this command, the Sector Count register should be loaded with the number of sectors per block. The drives support block sizes of 2, 4, 8 and 16 sectors.

When this command is received, the controller sets BSY and examines the Sector Count register contents. If they contain a valid and supported block count value, that value is loaded for all subsequent Read and Write Multiple commands, and execution of those commands is enabled. An invalid and unsupported block count in the register results in an Aborted Command error and disallows Read Multiple and Write Multiple commands.

Write Commands

Write Sector(s)

Writes from 1 to 256 sectors, beginning at a sector specified in the Command Block. (A sector count of 0 requests 256 sectors.)

When the Command register is written, the drive sets the DRQ bit and waits for the host to fill the sector buffer with the data to be written. An interrupt is not generated to start the first buffer fill operation.

Once the buffer is full, the drive resets DRQ, sets BSY, and begins command execution. If the drive is not already on the desired track, an implied seek is performed.

The data loaded in the buffer is written to the data field of the sector, followed by the ECC bytes. Upon command completion, the Command Block registers contain the cylinder, head and sector number of the last sector written. The next time the buffer is ready to be filled during back-to-back Write Sector commands, DRQ is set and an interrupt is generated.

After the host fills the buffer, DRQ is reset and BSY is set. If an error occurs, Write Sector operations terminate at the sector containing the error.

The Command Block registers then contain the numbers of the cylinder, head and sector where the error occurred. The host may read the Command Block to determine the nature of that error, and on which sector it happened. A Write Long may be executed by setting the Long bit in the command code. The Write Long command writes the data and the ECC bytes directly from the sector buffer; the drive itself does not generate the ECC bytes. Restrict Write Long commands to PIO Mode 0.

Write Verify Sector(s)

Identical to the Write Sector(s) command, except that the requested sectors are verified immediately after being written. The verify operation reads (without transferring), and checks for data errors. Any errors encountered during this operation are reported.

Write Sector Buffer

Allows the host to overwrite the contents of the drive’s sector buffer with a selected data pattern. When this command is received, the drive:

1. Sets BSY,

2. Sets up the sector buffer for a write operation,

3. Sets DRQ,

4. Resets BSY and

5. Generates an interrupt.

The host may then write up to 256 words of data to the buffer. A disk write task begins to store the host data to disk. Host write commands continue to be accepted and data transferred to the buffer until either the write command stack is full or the data buffer is full. The drive may reorder write commands to optimize drive throughput.

7 – 4

INTERFACE COMMANDS

Write Multiple

Performs similarly to the Write Sector(s) command, except that:

1. The controller sets BSY immediately upon receipt of the command,

2. Data transfers are multiple sector blocks and

3. The Long bit and Retry bit is not valid.

Command execution differs from Write Sector(s) because:

1. Several sectors transfer to the host as a block without intervening interrupts.

2. DRQ qualification of the transfer is required at the start of the block, not on each sector.

The block count consists of the number of sectors to be transferred as a block and is programmed by the Set Multiple Mode command, which must be executed prior to the Write Multiple command. When the Write Multiple command is issued, the Sector Count register contains the number of sectors requested — not the number of blocks or the block count.

If the number of sectors is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. This final, partial block transfer is for N sectors, where N = (sector count) modulo (block count)

The Write Multiple operation will be rejected with an Aborted Command error if attempted:

1. Before the Set Multiple Mode command has been executed, or

2. When Write Multiple commands are disabled.

All disk errors encountered during Write Multiple commands report after the attempted disk write of the block or partial block in which the error occurred.

The write operation ends with the sector in error, even if it was in the middle of a block. When an error occurs, subsequent blocks are not transferred. When DRQ is set at the beginning of each full and partial block, interrupts are generated.

Write DMA

Multi-word DMA

Identical to the Write Sector(s) command, except that:

1. The host initializes a slave-DMA channel prior to issuing the command,

2. Data transfers are qualified by DMARQ and are performed by the slave-DMA channel and

3. The drive issues only one interrupt per command to indicate that data transfer has terminated at status is available.

Ultra DMA

With the Ultra DMA Write protocol, the control signal (HSTROBE) that latches data from DD(15:0) is generated by the devices which drives the data onto the bus. Ownership of DD(15:0) and this data strobe signal are given to the host for an Ultra DMA data out burst.

During an Ultra DMA Write burst, the host always moves data onto the bus, and, after a sufficient time to allow for propagation delay, cable settling, and setup time, the sender shall generate a HSTROBE edge to latch the data. Both edges of HSTROBE are used for data transfers.

Any error encountered during Write DMA execution results in the termination of data transfer. The drive issues an interrupt to indicate that data transfer has terminated and status is available in the error register. The error posting is the same as that of the Write Sector(s) command.

7 – 5

INTERFACE COMMANDS

* Enabled at power up by default.

Set Feature Commands

Set Features Mode

Enables or disables features supported by the drive. When the drive receives this command it:

1. Sets BSY,

2. Checks the contents of the Features register,

3. Clears BSY and

4. Generates an interrupt.

If the value of the register is not a feature supported by the drive, the command is aborted. The acceptable values in the Features register are defined as follows:

VALUE DESCRIPTION

02h* Enabled write cache

03h Set transfer mode based on value in Sector Count register

44h Length of data appended on Read Long/Write Long commands specified in the

55h Disable read look-ahead feature

INTERFACE COMMANDS

Power Mode Commands

Standby Immediate – 94h/E0h

Spin down and do not change time out value. This command will spin the drive down and cause the drive to enter the STANDBY MODE immediately. If the drive is already spun down, the spin down sequence is not executed.

Idle Immediate – 95h/E1h

Spin up and do not change time out value. This command will spin up the spin motor if the drive is spun down, and cause the drive to enter the IDLE MODE immediately. If the drive is already spinning, the spin up sequence is not executed. The actuator is parked and some circuits are powered off.

Standby – 96h/E2h

Spin down and change time out value. This command will spin the drive down and cause the drive to enter the STANDBY MODE immediately. If the drive is already spun down, the spin down sequence is not executed. A non-zero value placed in the sector count register will enable the Automatic Power Down sequence. The timer will begin counting down when the drive returns to the IDLE MODE. A value of zero placed in the sector count register will disable the Automatic Power Down sequence.

Idle – 97h/E3h

Spin up and change time out value. This command will spin-up the spin motor if the drive is spun-down. If the drive is already spinning, the spin up sequence is not executed. A non-zero value placed in the Sector Count register will enable the Automatic Power Down sequence and their timer will begin counting down immediately. A value of zero placed in the Sector Count register will disable the Automatic Power Down sequence. The actuator is parked and some circuits are powered off.

Check Power Mode – 98h/E5h

This command returns a code in the Sector Count register that determines the current Power Mode status of the drive. If the drive is in, going to, or recovering from the STANDBY MODE the drive sets the Sector Count register to OOh. If the drive is in the IDLE MODE or ACTIVE MODE, the drive sets the Sector Count register to FFh.

Set Sleep Mode – 99h/E6h

This command will spin the drive down and cause the drive to enter the SLEEP MODE immediately. If the drive is already spun down, the spin down sequence is not executed.

Note: The only way to recover from SLEEP MODE is with a software reset or a hardware reset.

Default Power-on Condition

The drive’s default power on condition is the ACTIVE MODE.

Upon receiving a Power Mode command, except the SLEEP MODE command, the drive sets BSY and performs the requested power operation. Once the requested Power Mode change has begun, the drive resets BSY and generates an interrupt - without waiting for the drive to spin up or spin down. Upon receiving a SLEEP MODE command the drive is spun down, and when it is stopped, the drive resets BSY and generates an interrupt.

7 – 7

INTERFACE COMMANDS

255 21 minutes, 15 seconds

When enabling the Automatic Power Down sequence, the value placed in the Sector Count register is multiplied by five seconds to obtain the Time-out Interval value. If no drive commands are received from the host within the Time-out Interval, the drive automatically enters the STANDBY mode. The minimum value is 5 seconds.

TIMER VALUE TIME-OUT PERIOD

0 Time-out disabled

1 - 240 (value * 5) seconds

241 - 251 ((value - 240) * 30) minutes

252 21 minutes 253 Vendor unique period = 10

254 Reserved

While the drive is in STANDBY MODE, any commands received from the host are accepted and executed as they would in normal operation, except that the spin motor is started if required to execute a disk command. Under these conditions, the drive will set BSY when command processing would normally begin and will leave BSY set until the drive comes up to speed and the disk command can be executed. Disk commands issued while the drive is in STANDBY MODE, restarts the Time-out Interval after completing the command. A reset must be issued before attempting to issue any commands while the drive in SLEEP MODE.

INTERFACE COMMANDS

Initialize Drive Parameters

Enables the drive to operate as any logical drive type. The drive will always be in the translate mode because of Zone Density Recording, which varies the number of sectors per track depending on the zone. Through setting the Sector Count Register and Drive Head Register, this command lets the host alter the drive's logical configuration. As a result, the drive can operate as any equal to or less than capacity drive type. Do not exceed the total number of sectors available on the drive:

When this command is executed, the drive reads the Sector Counter Register and the Drive Head Register (and so determines the number of the logical sectors per track and maximum logical head number per cylinder and will calculate the number of logical cylinders.)

Upon receipt of the command, the drive:

1. Sets BSY,

2. Saves the parameters,

3. Resets BSY and

4. Generates an interrupt.

To specify maximum heads, write 1 less than the maximum (e.g. write 4 for a 5 head drive). To specify maximum sectors, specify the actual number of sectors (e.g. 17 for a maximum of 17 sectors/track).

The sector count and head values are not checked for validity by this command. If they are invalid, no error will be posted until an illegal access is made by some other command.

Moves the read/write heads from anywhere on the disk to cylinder 0. When this command is received, the drive:

1. Sets BSY and

2. Issues a seek to cylinder zero.

The drive waits for the seek to complete, then the drive:

1. Updates status,

2. Resets BSY and

3. Generates an interrupt.

If the drive cannot reach cylinder 0, the Error bit is set in the Status register, and the Track 0 bit is set in the Error register.

NOTE: If a maximum head and sector number is selected – such that the number of cylinders will exceed 65,535 – then the maximum cylinder value will be reduced to 65, 535.

7 – 12

INTERFACE COMMANDS

81 Slave drive failed

Seek, Format and Diagnostic Commands

Seek

Initiates a seek to the track, and selects the head specified in the Command block.

1. Sets BSY in the Status register,

2. Initiates the Seek,

3. Resets BSY and

4. Generates an interrupt.

The drive does not wait for the seek to complete before returning the interrupt. If a new command is issued to a drive during the execution of a Seek command, the drive will wait (with BSY active) for the Seek to complete before executing the new command.

Format Track

Formats the track specified in the Command Block. Shortly after the Command register is written, the drive sets the bit, and waits for the host to fill the sector buffer with the interleave table. When the buffer is full, the drive resets DRQ, sets BSY and begins command execution. If the drive is not already on the desired track, an implied seek is performed. Once at the desired track the data fields are written with all zeroes.

Execute Drive Diagnostic

Commands the drive to implement the internal diagnostic tests. (These tests are executed only upon command receipt; they do not run automatically at power up or after a reset.)

The drive sets BSY immediately upon receiving this command. The following table presents the codes and their descriptions. Note that the value in the Error register should be viewed as a unique 8 bit Code.

ERROR CODE DESCRIPTION

01 No error detected

00 Master drive failed

80, 82 Master and slave drives failed

Note: If a slave drive fails diagnostics, the master drive OR’s 80h with its own status, and loads that code into the Error register. If a slave drive passes diagnostics (or a slave is absent), the master drive OR’s 00 with its own status and loads that code into the Error register.

INTERFACE COMMANDS

S.M.A.R.T. Command Set

Execute S.M.A.R.T.

The Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) command has been implemented to improve the data integrity and data availability of hard disk drives. In some cases, a S.M.A.R.T. capable device will predict an impending failure with sufficient time to allow users to backup their data and replace the drive before data loss or loss of service.

The S.M.A.R.T. sub-commands (listed below) comprise the ATA S.M.A.R.T. feature set that provide access to S.M.A.R.T. attribute values, attribute thresholds and other logging and reporting information.

Prior to writing a S.M.A.R.T. command to the device’s command register, key values must be written by the host into the device’s Cylinder Low and Cylinder High registers, or the command will be aborted. For any S.M.A.R.T. sub-command, if a device register is not specified as being written with a value by the host, then the value in that register is undefined and will be ignored by the device. The key values are:

Key Register

4Fh Cylinder Low (1F4h) C2h Cylinder High (1F5h)

The S.M.A.R.T. sub-commands use a single command code (B0h) and are differentiated from one another by the value placed in the Features register. In order to issue a command, the host must write the subcommand-specific code to the device’s Features register before writing the command code to the command register. The sub-commands and their respective codes are:

D0h S.M.A.R.T. Read Attribute Value

This feature returns 512 bytes of attribute information to the host.

D1h S.M.A.R.T. Read Attribute Thresholds

D2h Enable/Disable Autosave

D3h S.M.A.R.T. Save Attribute Value

D4h Perform Off-Line Data Collection

D8h Enable S.M.A.R.T.

D9h Disable S.M.A.R.T.

DAh S.M.A.R.T. Return Status

This feature returns 512 bytes of warranty failure thresholds to the host.

To enable this feature, set the sector count register to F1h (enable) or 0 (disable). Attribute values are automatically saved to non-volatile storage on the device after five minutes of idle time and before entering idle, sleep or standby modes. This feature is defaulted to “enabled” when S.M.A.R.T. is enabled via the S.M.A.R.T. Enable Operations commands. The autosave feature will not impact host system performance and does not need to be disabled.

This feature saves the current attribute values to non-volatile storage.

Data is collected from random seeks, timed pattern seek times and head margin tests.

This feature allows the host to assess the status of a S.M.A.R.T. capable device by comparing all saved attribute values with their corresponding warranty failure thresholds. If no thresholds are exceeded, the drive is declared to have a positive health status. If any warranty failure threshold is exceeded, the drive is declared to have a negative health status. Executing this sub-command results in all attribute values being saved to non-volatile storage on the device.

DBh Enable/Disable Automatic Off-Line

To enable this feature, set the Sector Count register to F1h or 0 to disable.

A process of assigning designated areas of the disk to particular files.

ALTERNATE TRACK

A spare track used in the event that a normal track becomes damaged or is unusable.

ANALOG

A signal or system that does not use digital states to convey information. A signal may have any number of significant states (values), contrasted to digital signals which can only have two states.

ANSI

American National Standards Institute.

APPLICATION PROGRAM

A sequence of programmed instructions that tell the computer how to perform some end-user task, such as accounting or word processing.

AREAL DENSITY

Bit density (bits per inch) multiplied by track density (tracks per inch) or bits per square inch.

ASYMMETRY

A distortion of the readback signal which is shown in different intervals between the positive and negative voltage peaks.

AUXILIARY MEMORY

Memory other than main memory; generally a mass-storage subsystem containing disk drives and backup tape drives, controller(s) and buffer memory (also called peripheral memory).

AVERAGE ACCESS TIME

The average time to make all possible length accesses (seeks).

AVERAGE SEEK TIME

The average time to make all possible length seeks. A typical measure of performance.

BAD BLOCK

A block that cannot store data because of a media flaw.

BIT

An abbreviation for binary digit, of which there are two (0 and 1). A bit is the basic data unit of most digital computers. A bit is usually part of a data byte or word, but bits may be used singly to control or read logic “on-off” functions. The fundamental unit information, often used loosely to refer to a circuit or magnetization state at a particular instant in time.

BIOS

Acronym for Basic Input/Output System. The firmware area of a CPU that controls operations through the system bus and to the attached cards and peripheral devices.

BPI

Acronym for bits per inch. See bit density.

BLOCK

A group of bytes handled, stored, and accessed as a logical data unit, such as an individual file record.

BUFFER

A temporary data storage area that compensates for a difference in data transfer rates and/or data processing rates between sender and receiver.

BUS

A collection of functionally parallel conductors that forms an interconnection between functional blocks in a digital device. A length of parallel conductors that forms a major interconnection route between the computer system CPU (central processing unit) and its peripheral subsystems. Depending on its design, a bus may carry data, addresses, power, and more.

BYTE

An ordered collection of bits treated as a unit. Most often, a byte is understood to consist of eight bits. One byte is necessary to define an alphanumeric character.

CACHE

Random access memory (RAM) used as a buffer between the CPU and the disk drive.

CAPACITY

The amount of data, usually expressed in bytes, which can be stored in a given device or portion of same.

It includes the arithmetic logic unit (ALU) for performing all math and logic operations, a control section for interpreting and executing instructions, internal memory for temporary storage of program variables and other functions.

CHANNEL

A collection of electronic circuits used in the process of writing and reading information to and from magnetic media.

CHARACTER

An ordered collection of bits representing one of a set of predefined symbols. Often the term is used interchangeably with byte, but this is inexact.

CLOSED LOOP

A control technique that enables the positioning system to correct off-track errors in real time. The actual head position is monitored and compared to the ideal track position to determine any position error that might be occurring. This information is then used to produce a correction signal (feedback) that goes to the positioner to correct the error. (See also track following servo).

CLOSED LOOP SERVO

A servo control technique that uses position feedback to correct off-track errors. See Track Following Servo.

CLUSTER

The smallest allocatable unit of disk storage allowed by MS-DOS; each FAT entry represents one cluster.

CONTROLLER

An electronic device for connecting one or more mass storage peripherals (rigid disk drives, tape drives, and optical disk drives) to the input/output circuits of a host computer. Controllers vary in complexity, with more sophisticated units able to buffer and schedule commands, correct data errors, and bypass media defects without host intervention.

CONTROLLER

A miniature CPU dedicated to controlling a peripheral device, such as a disk drive, tape drive, video display terminal, or printer. The controller executes commands from the central processing unit and reissues commands to the peripheral device.

CORRECTABLE ERROR

An error that can be overcome by the use of Error Detection and Correction.

GLOSSARY

CYLINDER

On several disk surfaces sharing a common rotational axis, the aggregate of tracks at a given radial position. A set of disk tracks that are simultaneously under the set of read/ write heads. This three-dimensional storage volume can be accessed after a single seek.

CYLINDER ZERO

The outermost cylinder in a drive that can be used for data storage.

DATA

An ordered collection of information. In a specific case, it is the information processed by a computer.

DATA SEPARATOR

An electronic circuit which decodes playback data and produces separate clock and data bits. Sometimes incorrectly used to denote data synchronizer.

DATA SYNCHRONIZER

An electronic circuit producing a clock signal that is synchronous with the incoming data stream. This clock signal is then used to decode the recording code being used into user data.

DATA TRANSFER RATE

In a disk or tape drive, the rate at which data is transferred to or from the storage media. It is usually given in thousands of bits per second (Kbit/second) or millions of bits per second (Mbit/second).

DEDICATED LANDING ZONE

A designated radial zone on the disk where contact starting and stopping occur by design.

DEDICATED SERVO

A servo scheme in which a prerecorded pattern on an otherwise unused disk surface provides position information to the servo circuitry by means of a head reading that surface.

DEFECT

A magnetic imperfection in a recording surface.

DEFECT MANAGEMENT

A general methodology of avoiding data errors on a recording surface by avoiding the use of known bad areas of media. Usually defective sectors or tracks are retired and data are written in alternate locations. Several algorithms are possible such as “sector slipping,” or “spare sector per track.”

DEFECT MAP

A list of defects that fall within a pass/fail criteria of a user. This list is usually used by an operating system or a disk drive controller for defect management.

DEFECT SKIPPING

A defect management scheme for avoiding surface defects. It has data written before and after the defect, instead of using alternate tracks or sectors to avoid use of the defective area.

DENSITY

Generally, recording density. See areal, bit, and storage density.

DC ERASE

The method of erasing a track using a DC write/erase current through either a Read/ Write or Erase head.

DIGITAL

Any system that processes digital binary signals (having only values of a 1 or 0; usually in bits and bytes) rather than analog signals (signals that can have many values)

DIGITAL MAGNETIC RECORDING

See magnetic recording.

DIRECT ACCESS

Access directly to memory location. (See random access).

DIRECT MEMORY ACCESS

A mean of data transfer between the device and host memory without processor intervention.
