Before You Begin

Thank you for your interest in Maxtor hard disk drives. This manual provides technical information for OEM engi-

neers and systems integrators regarding the installation and use of Maxtor hard drives. Drive repair should be per-

formed only at an authorized repair center. For repair information, contact the Maxtor Customer Service Center at

800-2MAXTOR or 303-678-2045.

CAUTION: Maxtor hard drives are precision products. Failure to follow these precautions and guidelines outlined

here may lead to product failure, damage and invalidation of all warranties.

1 BEFORE unpacking or handling a drive, take all proper electro-static discharge (ESD) precautions,

including personnel and equipment grounding. Stand-alone drives are sensitive to ESD damage.

2 BEFORE removing drives from their packing material, allow them to reach room temperature. 3 During handling, NEVER drop, jar, or bump a drive. 4 Once a drive is removed from the Maxtor shipping container, IMMEDIATELY secure the drive through

its mounting holes within a chassis. Otherwise, store the drive on a padded, grounded, antistatic surface.

5 NEVER switch DC power onto the drive by plugging an electrically live DC source cable into the

drive's connector. NEVER connect a live bus to the drive's interface connector. (P68 only)

Please do not remove or cover up Maxtor factory-installed drive labels. They contain information required should the

drive ever need repair.

Regulatory Statements

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of

the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential

installation. Any modifications of this device - unless expressly approved by the manufacturer - can void the user’s

authority to operate this equipment under Part 15 of the FCC Rules. Operation is subject to the following two condi-

tions: (1) This device may not cause harmful interference and (2) This device must accept any interference that may

cause undesirable operation.

This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance

with the instructions, may cause harmful interference to radio communications. Howerver, there is no guarantee that

interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to

correct the interference by one or more of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

NOTE: Additional information on the need to interconnect the device with shielded (data) cables or the need for special devices, such

as ferrite beads on cables, is required if such means of interference suppression was used in the qualification test for the device. This

information will vary from device to device and needs to be obtained from the EMC group or product manager.

This Class B digital apparatus complies with Canadian ICES-003.

3.1 SAFETY, HANDLING, & ELECTROSTATIC DISCHARGE PROTECTION

3.1.1 Safety Precautions

For your safety, follow all safety procedures described here and in other sections of the manual.

• Remove power from the computer system (or expansion unit) before installing or removing the drive to prevent the possibility of electrical shock or damage to the drive. Unplug the unit containing the drive to provide an added measure of safety.

• Read, understand, and observe all label warnings.

3.1.2 Handling

Damage to the drive can occur as the result of careless handling, vibration, shock, or electrostatic discharge (ESD). Always handle the drive with care to avoid damage to the precision internal components.

Follow these guidelines to avoid damage to the drive:

• Always observe prescribed ESD precautions.

• Keep the drive in its anti-static bag until ready to install.

• Always use a properly fitted wrist strap or other suitable ESD protection when handling the drive.

• Hold drive only by its sides. Do not touch any components on the PCBA.

CAUTION: A 1/4-inch drop onto a hard surface can damage the drive.

Maxtor Atlas 10K V 3-1

• Always handle the drive carefully and gently. A drop of 1/4 inch onto a bench or desktop can damage a drive.

• Do not bump, jar, or drop the drive. Use care when transporting the drive.

• Always gently place the drive flat, PCB side down, on an appropriate ESD-protected work surface to avoid the drive being accidentally knocked over.

• Do not pack other materials with the drive in its shielded bag.

• Place the drive in the anti-static bag before placing in shipping container.

• Do not stack objects on the drive.

• Never force the drive or the mounting brackets into the drive bay.

• Do not expose the drive to moisture.

• Do not damage any seals on the drive; doing so may void the warranty.

3.1.3 Electrostatic Discharge (ESD) Protection

Various electrical components within the disk drive are sensitive to static electricity and Electrostatic Discharge (ESD). Even a static buildup or discharge that is too slight to feel can be sufficient to destroy or degrade a component's operation.

To minimize the possibility of ESD-related damage to the drive, we strongly recommend using both, a properly installed workstation anti-static mat and a properly installed ESD wrist strap. When correctly installed, these devices reduce the buildup of static electricity which might harm the drive.

• Observe the following precautions to avoid ESD-related problems:

• Use a properly installed anti-static pad on your work surface.

• Always use a properly fitted and grounded wrist strap or other suitable ESD protection when handling the drive and observe proper ESD grounding techniques.

• Hold the drive only by its sides. Do not touch any components on the PCBA.

• Leave the drive in its anti-static bag until you are ready to install it in the system.

• Place the drive on a properly grounded anti-static work surface pad when it is out of its protective anti-static bag.

• Do not use the bag as a substitute for the work surface anti-static pad. The outside of the bag may not have the same anti-static properties as the inside. It could actually increase the possibility of ESD problems.

• Do not use any test equipment to check components on the electronics module. There are no user-serviceable components on the drive.

Figure 3-1 Shows The Mechanical Dimensions of the drives.

Figure 3-1 Dimensions for the Maxtor Atlas 10K V Hard Disk Drives

Maxtor Atlas 10K V 3-3

3.2.1 Shock Feet

Maxtor Atlas 10K V hard disk drives are outfitted with plastic shock feet on the bottom edge of the base casting, near the corners, beneath the side mounting holes (translucent), and near the corners of the top cover next to the screws (black). The shock feet give an additional level of isolation to prevent the head and disk damage that occasionally occurs during unpacking, staging, and installation. The shock feet attenuate the short-pulse shocks that occur when placing the drive on a hard surface. If the drive is tested on a hard surface, it should be supported such that the shock feet are not in contact with a hard surface (the drive should be supported in the middle, between the shock feet).

Note: To provide optimal protection the shock feet are designed to ex-

ceed the form factor when uncompressed.

3.3 UNPACKING INSTRUCTIONS

CAUTION: The maximum limits for physical shock can be exceeded if

the drive is not handled properly. Special care should be

taken not to bump or drop the drive.

1. Open the shipping container and remove the packing assembly that contains the drive.

2. Remove the drive from the packing assembly.

CAUTION: During shipment and handling, the antistatic electrostatic dis-

charge (ESD) bag prevents electronic component damage due to electrostatic discharge. To avoid accidental damage to the drive, do not use a sharp instrument to open the ESD bag. Save the packing materials for possible future use.

3. When you are ready to install the drive, remove it from the ESD bag.

Note: 0 = No Jumper, 1 = Jumper Installed

Configure the drive for remote (external) SCSI ID selection by removing the SCSI ID jumpers (if present) from the referenced SCSI ID pins. Then connect the leads from the external selection switch to the referenced pins. Observe the following guidelines while doing so:

• ID bit 0, at Pin 8, is the Least Significant Bit.

• SCSI ID bits 0, 1, 2, and 3 (pins 8, 6, 4, and 2, respectively) are active LOW signals. That is, the bit is a 1 if the corresponding remote switch is closed to ground or jumper installed.

• Use pins 1, 3, 5 and 7 as the associated ground returns for ID bits 3, 2, 1, and 0, respectively.

3.4.2.1 Write Protection

To configure Write Protection for the drive, install a jumper across pin pair 11/12 on the J3 Option Header. To disable Write Protection on the drive, remove the jumper.

3-8 Maxtor Atlas 10K V

3.4.2.2 Delay Spin (DS), Stagger Spin (SS)

Maxtor Atlas 10K V drives have three Spin Up modes:

Option 1 (No jumpers installed):

Spi n up i mme dia te l y wh en p ow e r is app li e d. V er i fy th at n o jum p er i s ins t all ed across the Delay Spin pin pair of the J3 Option Header.

Option 2 (Delay Spin jumper installed):

Spin up on START STOP UNIT command: Install the jumper across pin pair 15/16 (GND/Delay Spin) on the J3 Option Header.

3.4.2.3 Single-Ended Operation – Force SE (Disable LVD)

Install a jumper across pin pair 17/18 (SE) on the J3 Option Header to operate the disk drive as a single-ended device. Remove the SE jumper for LVD operation and monitoring of the DIFFSENS signal.

3.4.2.4 Remote Busy and Fault Displays

Busy and Fault status of the drive can be monitored remotely by connecting a remote (external) Busy and/or remote Fault display LEDs.

Remote Fault LED

On the J1 Option Connector, connect the cathode side of the remote Fault LED to pin 2, Fault LED. Connect the anode side of the LED to pin 11, +5V.

3.4.3 SCA-2 80-Pin Connector Versions

This section describes the SCA-2 (Single Connector Attachment) 80-pin connector for Maxtor Atlas 10K V drives with the following features:

• SCSI ID

•Spin Up

• Activity LED displays

Use Figure 3-4 to locate the appropriate pins for configuring the drive. Note that

Figure 3-4 does not call out each of the 80 pins on the connector, but rather illustrates the layout of the pins.

Note: The SCA-2 Connector version of the disk drives does not provide

the following jumper configuration: TERMPWR, Active Termination, or Write Protection.

3.4.3.1 Termination for the 80-Pin SCA-2 Connector Versions

CAUTION: These versions of Maxtor Atlas 10K V disk drives cannot be

configured to provide bus termination. Therefore, be sure to properly terminate the SCSI bus on which this drive is installed.

Note: Refer to your system or SCSI controller documentation regard-

ing any additional recommendations regarding drive placement on the SCSI bus and SCSI bus termination.

3-10 Maxtor Atlas 10K V

3.4.3.2 SCSI ID for SCA-2 Versions

Each SCSI device on the bus must have a unique SCSI ID number assigned to it. The drive can be configured for SCSI ID numbers that range from 0 through 15.

Configure the SCSI ID by providing the proper open or ground signal inputs to the referenced pins of the drive’s 80-pin new version SCA-2 connector (Figure 3-4). Refer to Table 3-2 for SCSI ID pin assignments.

Note: Refer to your system or SCSI controller documentation for spe-

cific recommendations about assigning SCSI ID numbers for your specific system.

3.4.3.3 Spin Up for the 80-Pin SCA-2 Connector Versions

Maxtor Atlas 10K V drives have three Spin Up modes:

Option 1 Spin up occurs immediately when power is applied.

Option 2 Drive spin up occurs after a predetermined delay following power on.

Set the delay parameters with the MODE SELECT Command, Maxtor (Vendor) Special Function Control Page (39h).The delay is equal to a user-specified multiplier multiplied by the numerical SCSI ID of the drive. This will give a staggered spin-up in multiple-drive installations.

Option 3 Drive spin up is controlled by the START STOP UNIT command.

Configure the desired spin up option (Table 3-3) by setting the state of the DELAY_SPIN (Pin 38) and STAGGER_SPIN (Pin 78) inputs on the 80-pin SCA2 connector (Figure 3-4). The states of these signals are set by using either hardwired connections at the backplane or backplane logic.

3.4.3.4 Activity LED for SCA-2 Connector Versions

The drive provides the output BUSY_OUT signal to power a user-supplied activity LED.

The output indicates the drive is performing a SCSI operation. To use this output, connect a user-supplied LED cathode to the BUSY_OUT connection, pin 77 on the SCA Connector (Figure 3-4). The LED anode must be attached to the proper +5 VDC supply through an appropriate current-limiting resistor.

3.6 DRIVE MOUNTING AND INSTALLATION

Drive mounting orientation, clearance, and ventilation requirements are described in the following subsections.

3.6.1 Orientation

The mounting holes on the Maxtor Atlas 10K V hard disk drive allow the drive to be mounted in any orientation. Figure 3-6 shows the location of the three mounting holes on each side of the drive. The drives also can be mounted using the four mounting hole locations on the PCB side.

All dimensions are in millimeters. For mounting, #6-32 UNC screws are recommended.

Figure 3-6 Mounting Dimensions Maxtor Atlas 10K V Drives

Maxtor Atlas 10K V 3-21

3.6.2 Mounting Screw Clearance

The printed-circuit board assembly (PCBA) is very close to the mounting holes. Figure 3-7 specifies the clearance between the screws in the mounting holes and the PCBA. Do not use mounting screws longer than the maximum lengths specified in Figure 3-7. The specified screw length allows full use of the mounting-hole threads, while avoiding damaging or placing unwanted stress on the PCBA. Clearance from the drive to any other surface (except mounting surfaces) must be a minimum of

1.25 mm (0.05 inches).

Figure 3-7 Mounting Screw Clearance for Maxtor Atlas 10K V Drive

CAUTION: The PCB is very close to the mounting holes. Do not exceed the speci-

fied length for the mounting screws. The specified screw length allows full use of the mounting-hole threads, while avoiding damaging or placing

unwanted stress on the PCB.

Figure 3-7 specifies the minimum clearance between the PCB and the screws in the mounting holes. The maximum torque applied to the screws must not exceed 8.6 inch-pounds.

3-22 Maxtor Atlas 10K V

3.6.3 Mounting

For the best results during performance benchmark testing, it is highly recommended that the drive be mounted firmly in a system or fixture, rather than sitting unconstrained on a tabletop. If it is necessary to do early testing of the drive while it is unconstrained, the drive should rest on a flat, smooth, semi-cushioned surface (similar to a mousepad). The drive should not be operated on a hard surface—this avoids performance degradations due to the higher incidence of recovered errors.

3.6.4 Ventilation

The Maxtor Atlas 10K V hard disk drive may operate with or without a cooling fan provided that the maximum HDA temperature as measured on the drives’s top cover does not exceed 131×F (60×C). Drive reliability and warranty will be limited if the drive is exposed to temperatures greater than 60×C. Figures 3-8 and 3-9 show airflow recommended for adequate cooling. Clearance from the drive to any other surface above and below the drive must be a minimum of 1.25mm (1/16 inch). Maxtor leaves the design and application of cooling and clearance for the disk drive to the User, but the drive must maintain a case temperature at or below 60×C.

Note: Seek time is defined as the time required for the actuator to seek

to a new position and settle on a track. It is measured by averaging the execution time of a minimum of 1000 operations of the indicated type as shown in Table 4-1. The seek times include head settling time, but do not include command overhead time, time spent reading or writing data, or rotational latency delays. Unless otherwise specified, read/seek command settling criteria is assumed.

4.2 FORMATTED CAPACITY

At the factory, the Maxtor Atlas 10K V receives a low-level format that creates the actual tracks and sectors on the drive. Table 4-2 shows the capacity resulting from this process. Formatting done at the user level for operation with DOS, UNIX, or other operating systems, will result in less capacity than the physical capacity shown.

4.5 POWER

The Maxtor Atlas 10K V hard disk drive operates from two supply voltages:

+12 V +/-10% @ Spin up, +/- 5% While running

+5 V +/- 5%

Allowable ripple and noise for each voltage:

+12 V 800 mV p-p (100 Hz to 8 KHz)

+5 V 250 mV p-p (100 Hz to 20MHz)

4.5.1 Power Sequencing

MAXTOR ATLAS 10K IV 73.5/147.1/300 GB

450 mV p-p (8 KHz to 20 KHz)

250 mVp-p (20KHz - 20MHz)

You may apply the power in any order or manner, or open either the power or power return line with no loss of data or damage to the disk drive. However, data may be lost in the sector being written at the time of power loss. The drive can withstand transient voltages of +10% to –10% from nominal while powering up or down.

4.5.2 Power Reset Limits

When powering up, the drive remains reset (inactive) until both rising Voltage thresholds reset limits are exceeded for 100 ms. When powering down, the drive resets immediately when either supply voltage drops below the falling voltage threshold.

Uncorrectable read errors

1. Recovered read errors are errors which require retries for data correction. Errors corrected by ECC on-the-fly are not considered recovered read errors. Read on arrival is disabled to meet this specification.

2. Uncorrectable read errors are those that are not correctable using an Error Correcting Code (ECC), or retries within the retry limits specified in the mode pages. The drive terminates the command either when a repeating error pattern occurs, or after both the specified number of retries and application of triple burst error correction fail to correct the error.

3. A seek error occurs when the actuator fails to reach or remain on the requested cylinder, and/or the drive requires the execution of the full calibration routine to locate the requested cylinder.

SCSI Description

This chapter contains an overview of SCSI command and status processing and a detailed description of the commands supported by the disk drives. The SCSI command system enables the initiator to instruct the drive to perform specific functions.

In this manual, unless otherwise stated, numerical values are given in decimal. Hexadecimal numbers, such as opcodes, are always given with an “h” following, as in 5Ah except when entire data tables are in hexadecimal.

5.1 Overview of the SCSI Command Descriptions

The disk drives support the SCSI-3 commands listed in Table 5-1. The command categories are sequential, normal, and immediate.

Immediate commands are processed when received by the drive. In most cases, these commands do not require drive resources, do not change the state of the drive, and bypass the command queue (unless the command is tagged).

Chapter 5

Sequential commands execute in the order that they arrive (unless accompanied by

a HEAD OF QUEUE tag) and execute to completion before a subsequent command is activated.

Normal commands are allowed to execute concurrently (with the restriction that the drive executes overlapping writes in the order received). Normal commands are usually I/O commands

1. Relative Addressing is not supported by the drive. Therefore, in all I/O commands, the RelAdr bit must be 0.

2. RESERVE and RELEASE are supported, as are third-party reservations. Extent reservations are not supported.

3. The RECEIVE DIAGNOSTIC RESULTS and SEND DIAGNOSTIC DATA commands implement vendor-unique pages to test the drive during the manufacturing process. It is recommended that initiators specify only the non-page format variants of these commands (PF=0), except for page 0x40.

Maxtor Atlas 10K V 5-3

5.2 Command Descriptor Block

An initiator communicates with the drive by sending a 6-, 10-, or 12-byte Command Descriptor Block (CDB) that contains the parameters for the specific command. The SCSI command's operation code is always the first byte in the CDB and a control field is the last byte. For some commands, the CDB is accompanied by a list of parameters sent during the data-out buffer transfer. Table 5-2 shows the format of a typical sixbyte CDB.

Operation Code The first byte of a SCSI CDB contains an operation code. The operation code of the CDB has

a Group Code field (bits 7-5) and a Command Code field (bits 4-0). The 3-bit Group Code field provides for eight groups of command codes. The 5-bit Command Code field provides for 32 command codes in each group. A total, therefore, of 256 possible operation codes exist. Operation codes are defined in the SCSI command standards. The group code for CDBs specified therein correspond to the length of the command descriptor as below:

Commands that use one byte for the transfer length value allow up to 256 sectors of data to be transferred by one command. A transfer length value of 0 indicates that 256 sectors are to be sent. Transfer length values of 1 through 255 indicate the number of sectors to be transferred.

Commands that use multiple bytes for the transfer length value function differently. A transfer length value of 0 indicates that no data transfer is to occur. Transfer length values of 1 or greater indicate the number of sectors to be transferred.

cated for returned data. The Allocation Length is used to limit the amount of data returned to the initiator.

An Allocation Length of 0 indicates that no data is to be transferred from the drive to the initiator. The drive terminates the data-in buffer transfer when the specified number of bytes have been transferred to the initiator or when all available data has been transferred, whichever is less.

5-6 Maxtor Atlas 10K V

5.3 Status/Error Reporting

SCSI message-level errors are communicated by messages that are defined specifically for that purpose. SCSI command-level errors are communicated by a status that is returned by the drive during the STATUS phase. This phase occurs at the end of each command, unless the command is terminated by one of the following events:

• ABORT TASK SET message

•ABORT TASK message

• TARGET RESET message

•CLEAR QUEUE message

• Unexpected disconnect

The status code is contained in bits 1 through 5 of the status byte. Bits 0, 6, and 7 are reserved. Table 5-6 describes the status codes returned by the drive.

Table 5-6 Status Codes

Status Definition Meaning

00h GOOD The drive successfully completed the command.

02h CHECK CONDITION An Auto Contingent Allegiance (ACA) condition occurred.

The drive cannot service the command at the moment, and its Command Descriptor Block has been discarded. The initiator can retry the command at a later time. This status is returned when:

08h BUSY

10h INTERMEDIATE

18h RESERVATION CONFLICT

28h TASK SET FULL

5.4 Linked Commands

An I/O Process (task) may contain multiple commands that are linked together. The initiator communicates this condition of linked (or unlinked) commands by setting (or clearing) the Link bit of the Command Descriptor Block’s control word. A linked

• A non-tagged command is received and the logical unit's command queue is full (all internal command buffers are in use).

• A disconnect privilege was not granted in the IDENTIFY message of a queue-tagged I/O process (Parallel SCSI).

• A disconnect privilege was not granted in the IDENTIFY message of a non-tagged I/O process and a command from another initiator is currently active (Parallel SCSI)

• A command is received while an auto-contingent allegiance condition exists for another initiator.

This status is returned for every command (except the last) in a series of linked commands that was successfully completed. However, if the command is terminated with other that GOOD status (such as CHECK CONDITION, RESERVATION CONFLICT, OR BUSY), the INTERMEDIATE status is not returned and the series of linked commands and the task is ended.

Another initiator has reserved the drive. (This status is never returned for INQUIRY or REQUEST SENSE commands.)

The drive cannot service the command at the moment, and its Command Descriptor Block has been discarded. (Returned for a tagged command when all of the drive's internal command buffers are in use, or when a host sends a tagged command while an Auto Contingent Allegiance condition is pending for that initiator)

Maxtor Atlas 10K V 5-7

command is one in which the Link bit in the Command Descriptor Block is set. After successful completion of a linked command the drive sends an INTERMEDIATE status, followed by a LINKED COMMAND COMPLETE message. If the Flag bit was set in the Command Descriptor Block, the drive sends an INTERMEDIATE status, followed by a LINKED COMMAND COMPLETE (WITH FLAG) message. The drive then switches the bus to the command phase in order to receive the next command in the linked chain.

All commands in a linked chain are addressed to the same nexus and are part of a single task (I/O process). The drive defers any commands that are not part of the linked chain until the chain is complete. The last command in the chain has the Link bit cleared.

Note: Relative addressing is not supported by the Atlas 10K disk drive.

5.5 DATA Transfer Command Components

Many of the SCSI commands cause data to be transferred between the initiator and the drive. The content and characteristics of this data are command-dependent. Table 5-8 lists the information transmitted for all of the commands.

The “Length in CDB” column of Table 5-8 identifies the Command Descriptor Block field used by the drive to determine how much command-related data are to be transferred. The units (bytes or logical blocks) for the different Length fields are implied by the Length Field Name as shown in Table 5-7:

Table 5-7 Length Fields

Field Name Units Implied

Allocation Length Bytes of data the drive is allowed to send to the initiator

Parameter List Length Bytes of data the initiator has available for the drive

Transfer Length Logical data sectors the initiator wants transferred or verified

Byte Transfer Length Bytes of data the initiator wants transferred

The DATA OUT column in Table 5-8 lists the information passed to the drive by the initiator as part of the command. The DATA IN column lists the information sent to the initiator by the drive.

Numbers in parentheses after an item indicate the item’s length in bytes. In some cases, additional length information is communicated during the DATA phase. For example, a FORMAT UNIT Defect List Header contains a Defect List Length field that contains the total length of the Defect Descriptors that follow the Defect List Header. Table 5-8 does not include these cases.

5.6 SCSI COMMAND DESCRIPTIONS

The SCSI command descriptions that follow this page contain detailed information about the SCSI commands that are supported by the drive. Each description provides a Data Format and Field Descriptions for the Command Descriptor Block for the described command.

The commands are presented in alphabetic order, and each command starts on a new, odd-numbered page.

Common Fields

Several fields that are common to many commands are described here, rather than being repeated throughout the descriptions. These fields include:

Reserved – Reserved bits, fields, bytes, and code values are set aside for future standardization and must be set to 0. If the drive receives a command that contains non-0 bits in a reserved field or a reserved code value, the command is terminated with a CHECK CONDITION status and the sense key set to ILLEGAL REQUEST. However, there are some fields that are not checked for compatibility with older SCSI initiators.

Control – The Link Bit and Flag Bit are supported.

RelAdr – Not supported; must be 0.

5.7 CHANGE OPERATING DEFINITION (40h)

The CHANGE DEFINITION command shown in Table 5-9 and Table 5-10 set the SCSI compliance for disk drives with parallel SCSI interfaces to one of four different levels: SCSI-1, SCSI-1/CCS, SCSI-2 or SCSI-3.

5.8 FORMAT UNIT Command (04h)

The FORMAT UNIT command formats the disk's storage media into initiatoraddressable logical blocks according to initiator-defined options. This command ensures that the disk storage media is formatted so that all data sectors are accessible. Any data residing on the disk before this command is invoked is lost. This command repairs damage left by previous WRITE LONG commands. The WRITE LONG command allows the initiator to deliberately corrupt a sector's ECC or EDC.

The FORMAT UNIT command updates the defective sector list, referred to as the Grown Defect List, that is maintained by the drive. As described below, the drive gives the initiator considerable control over this list. If certification is enabled, all initiatoraddressable logical blocks are verified, and bad sectors are reassigned and added to the Grown Defect List.

Note: During FORMAT UNIT command processing, the drive ig-

nores the Read/Write AWRE and ARRE bits (from Error Recovery Mode page) and does auto-revectoring as needed.

The drive is physically formatted when it leaves the manufacturing facility. Therefore, it is not necessary to reformat the drive before using it. If the logical sector size of the drive is changed using the Block Descriptor of the MODE SELECT Command, it is recommended (but not necessary) to reformat the drive.

The Immed bit that can be included in the FORMAT UNIT command parameter list allows the initiator to control whether the drive returns completion status either after fetching and validating the Command Descriptor Block and parameter list or after the FORMAT UNIT command completes. The FORMAT UNIT command parameters are described in Table 5-11 and Table 5-12

The time required for the FORMAT UNIT command to format the disk primarily depends on the capacity of the drive. The number of defects detected and the number of defects already in the Primary and Grown Defect Lists also influence the time required to format the drive. If the Disable Certification bit is set to 1, formatting time is reduced.

Defective sectors on the drive are managed through two lists: the Primary Defect List and the Grown Defect List. The Primary Defect List is created when the drive is manufactured and is the drive's initial defect list. The Primary Defect List is not affected by the FORMAT UNIT command. Sectors listed in it are revectored by the drive. The Grown Defect List contains a list of the sectors that have gone bad since the drive's primary list was generated.

Defects are communicated in a data structure referred to as a Defect Descriptor. The SCSI specification defines several Defect Descriptor formats. The FORMAT UNIT command recognizes defect descriptors in Block format, Bytes From Index format, and Physical Sector format. (There is one exception: a value of FFFFFFFFh in either the defect Bytes From Index field or the Defective Sector Number fields is ignored).

When the Complete List value is 0, the drive adds initiator-supplied and newly found defective Logical Block Numbers to the existing Grown Defective List.

The Defect List Format value specifies the defect descriptor passed by the initiator to the drive when the Format Data value is 1. Acceptable values are: 000b (Block [or Sector] Format) 100b (Index Format) 101b (Physical Sector Format)

5.8.1 Five Forms of FORMAT UNIT Commands

Five different forms of the FORMAT UNIT command are supported through different combinations of the Format Data bit, Complete List bit, and the information in the Defect List Length field. (Refer to FORMAT UNIT Defect Header List for a description of the Defect List Length field.) The different command forms give the initiator control over the contents of the Grown Defect List. Table 5-13 describes the contents of the Grown Defect List after FORMAT UNIT command execution.

All sectors found to be bad, but not listed in the Primary Defect List or Grown Defect List, are added to the Grown Defect List.

The existing Grown Defect List is discarded. A new Grown Defect List is generated, containing All sectors found to be bad, but not listed in the Primary Defect List.

The Grown Defect List contains: Original Grown Defect List All sectors found to be bad, but not listed in the Primary Defect List. A list of sectors supplied by the initiator. These sectors are passed in defect descriptors in the data-out buffer transfer that occurs as part of the FORMAT UNIT command.

Same as the case above, except that the current Grown Defect List is discarded before formatting begins.

5.8.2 FORMAT UNIT Parameter List

The FORMAT UNIT Parameter List (Table 5-14) consists of a Defect List Header (Table 5-15) followed by one or more Defect Descriptors. Descriptors are either four bytes or eight bytes in length.

5.8.2.1 FORMAT UNIT Defect List Header

The FORMAT UNIT Defect List Header (Table 5-15) provides several optional format control bits to give the initiator more control over the defect lists. Table 5-16 provides descriptions of the data fields in the Defect List Header

The Format Options Valid bit indicates that the remaining option bits in this byte are valid. If this bit is not set, the remaining bits, except Immed, are ignored.

The Disable Primary bit specifies whether the drive should ignore the Primary Defect List during the format to identify defective areas on the media. The drive's default is 0, indicating that the drive should replace sectors found in the Primary Defect List during the format.

The Disable Certification bit specifies whether the drive should certify the media during the format. The drive’s default is 0, indicating that the drive should certify the media.

The Stop Format bit specifies the error conditions under which the drive is to terminate the format. The state of the bit is ignored and the drive acts as if this bit is set. If either the Grown Defect List or the Primary Defect List is not found, the format operation terminates with a CHECK CONDITION status and a sense key of MEDIUM ERROR

The Initialization Pattern bit signals the drive that the FORMAT UNIT Parameter List contains initialization pattern information. An Initialization Pattern bit of 1 indicates that an initialization pattern descriptor (Table 5-

17) is included in the FORMAT UNIT parameter list immediately following the Defect List Header. An Initialization Pattern bit of 0 indicates that an initialization pattern descriptor (Table 5-

17) is not included in the FORMAT UNIT parameter list, and the drive will use its default initialization pattern of all zeros.

The Disable Saving Parameter prohibits the drive from preserving MODE SELECT parameters received while the Format is in progress. This bit is ignored, and the drive acts as if it were set.

When the Immediate bit is 0, the drive returns a status after the format operation completes. If the disconnect privilege is granted in the accompanying IDENTIFY message, the drive disconnects from the bus after fetching and validating the Command Descriptor Block and the FORMAT UNIT Parameter List. If the disconnect privilege is not granted, the drive stays connected to the bus during the entire FORMAT UNIT command. When the Immediate bit is set to 1, the drive returns a status after the Command Descriptor Block and FORMAT UNIT Parameter List have been fetched and validated. In this case, the drive ignores the IDENTIFY message's disconnect privilege bit and remains connected to the bus while it validates the Command Descriptor Block and Parameter List. It returns the completion status before it disconnects. The drive then proceeds with the format.

Gives the length in bytes of the Defect Descriptors that follow. A value of 0 is valid and means that no Defect Descriptors follow. A CHECK CONDITION status is returned if this value is not a multiple of the defect descriptor size. The Defect List Length is equal to four times the number of defect descriptors if Block format is used, or eight times if Bytes From Index format or Physical Sector format is used.

5.9 INQUIRY Command (12h)

The INQUIRY command allows the initiator to determine the kind of SCSI devices attached to its SCSI bus. It causes a device that is attached to a SCSI bus to return information about itself. The drive identifies itself as a Direct Access Storage Device that implements the applicable interfacing protocol. The drive does not need to access its storage medium to respond to the inquiry. The INQUIRY commands are described in Table 5-22 and Table 5-23.

The drive can provide two categories of data in response to an INQUIRY command: Standard Inquiry Data and Vital Product Data. Standard Inquiry Data contains basic data about the drive, and Vital Product Data comprises several pages of additional data. Each Vital Product Data page requires a separate INQUIRY command from the initiator.

An INQUIRY command is not affected by, nor does it clear, a Unit Attention condition.

5.11 LOG SENSE Command (4Dh)

Note: Log Sense data pages require special interpretation and also are

subject to change. For assistance with the Log Sense data pages, contact your Maxtor Applications Engineer.

The drive collects operational information and stores these statistics as log data. Log data are grouped by category into log pages. The LOG SENSE command allows an initiator to retrieve the stored log data. The LOG SENSE command is a complementary command to the LOG SELECT command.

Table Table 5-40 lists the log pages supported by the drive. Contact your Maxtor Applications Engineer for more information.

The Parameter Pointer Control bit controls the type of parameters that can be requested from the drive. This bit must be 0, indicating that all log parameters for the specified page (subject to the allocation length specified) are returned to the initiator.

The Save Pages bit specifies whether the parameters are to be saved. This bit must be 0, indicating that no parameters are to be saved and are reset at power-on or by a TARGET RESET.

The Page Control field defines the type of parameter values to be selected. The field must be 01b indicating that the current values are to be returned. Mode 11b (return default values) is not supported because all counters have a default value of 0.

The value specified as the Page Code determines the page to be returned. Table 5-40 contains a list of supported log pages and their page codes.

This specifies the number of bytes of data that the drive is allowed to pass during the DATA IN phase. The requested page is truncated if its length exceeds the number of bytes specified in this field.

Maxtor Atlas 10K V 5-31

5.11.2 LOG SENSE Log Pages

The log pages that are returned from the drive have a common format that is shown in Table 5-43. Each page contains a 4-byte header followed by one or more log parameters. Refer to Table 5-44. Table 5-45 contains the format for the Generic Log Parameter and Table 5-46 describes the fields.

Threshold Met Comparison. This parameter is always 0. The drive does not use thresholds for any of its parameters.

List in Binary. This bit only valid if LP = 1. If LP = 1 and LBIN = 0, then the List Parameter is a string of ASCII graphic codes (code values 20h through 7Eh). If LP = 1 and LBIN = 1, then the parameter is a list of binary information.

List Parameter. When 0, indicates that the parameter value for this parameter is a numeric value. When LP is a 1, it indicates that the parameter value is an alphanumeric ASCII-string list. This parameter is always 0.

Contains the parameter’s current value when the PC field of the LOG SENSE command is 01b.

Note: The DU, DS, TSD, ETC, TMC, LBIN and LP fields are collec-

tively referred to as the Parameter Control Byte. This byte generally has a value of 0; however, if the page is non-volatile but the drive is not spun up or the GLTSD bit is set in Mode Page 0Ah, then the value would be 20h. If the page is volatile, then the value is 60h.

5.12 MODE SELECT (6) Command (15h)

SCSI refers to the drive’s operational parameters as its mode parameters. SCSI groups the mode parameters by function into a set of data structures referred to as mode pages. The MODE SELECT (6) command allows the initiator to modify some of these mode pages and thereby control some of the drive’s operational characteristics. The Save Page (SP) option in the Command Descriptor Block makes the changes permanent. The new mode parameters are then stored in the drive’s non-volatile memory. The MODE SELECT CDB is described in Table 5-47 and a description of the fields in Table 5-48.

Table 5-48 MODE SELECT (6) Command Field Descriptions

Data Field Description

Page Format. The drive ignores the content of this field and produces a mode parameter list that contains a mode header optionally followed by a sector descriptor and one or more pages that conform to the format shown here.

Save Pages. When SP = 0, the drive performs the specified MODE SELECT operation and does not save any pages. When SP = 1, the drive performs the specified operation and stores all savable pages, (PS =1 on MODE SENSE return) including any sent during the data-out buffer transfer. The changes made when SP = 1 become permanent changes to the drive’s SCSI setup.

This field tells the drive how many bytes of Mode Parameters to fetch in the data-out buffer transfer. A CHECK CONDITION status is returned if this value truncates a page.

5.12.1 Initiator-Changeable Mode Pages

Table 5-49 lists the mode pages that are supported by the drive. An initiator can change these pages by supplying them, with the desired changes included, in the MODE SELECT command’s data-out buffer transfer.

The initiator should first use a MODE SENSE command to read the appropriate pages and leave non-changeable values as read when the initiator subsequently writes the changeable pages with the MODE SELECT command. If a non-changeable field contains an invalid value, the drive returns a CHECK CONDITION status.

5.12.2 Mode Page Types

The drive maintains three distinct sets of mode pages. They are the current page, the default page, and the saved page. The drive also reports a fourth set of changeable pages.

The page types are defined in Table 5-50.

Table 5-50 Mode Page Types

Page Type Definition

The current mode page set applies to all initiators and defines the drive’s mode. The SCSI-2 specification states that a drive can maintain Mode parameters on a per-initiator basis if it so chooses. The Drives do not support this option.

The current mode page set contains the values supplied in the last MODE SELECT command re-

Current

Default

Saved

Changeable

ceived from an initiator. If no initiator has sent a MODE SELECT command since the drive was last reset or powered up, the current pages contain

• Saved values if saved pages exist (from a previous MODE SELECT command SP parameter).

• Default values if pages have never been saved.

The drives generate a Unit Attention condition for all initiators (except for the one that was the source of the MODE SELECT command) whenever one initiator modifies the Mode parameters.

The default mode page set contains the factory default values that are listed in each page’s description.

The saved mode page set contains values preserved in the drive’s non-volatile memory by a previous SP-modified MODE SELECT command.

The changeable mode page set provides a means for an initiator to determine which pages it is allowed to change and the specific bits within those pages that it is allowed to change. This page set is read-only and is fetched with a MODE SENSE command.

5.12.3 Mode Parameter List

Table 5-51 shows the format of the Mode Parameter List that is passed by the initiator to the drive during the command’s data-out buffer transfer. Table 5-52 describes the fields. Table 5-53 and Table 5-54 provides a description of the data format and fields of the Mode Parameter Header. Table 5-55 and Table 5-56 describe the format and field descriptions for the Mode Parameter Block Descriptor.

affect the drives processing. The drive uses the value in the field and, if the SP bit is set, preserves the new value of the field in non-volatile memory on the drive. (The PS bit must have been set when the mode page was returned with a MODE SENSE command.)

Ignored

A value in this field is never used or validated; it is never looked at by the drive. Ignored fields are not underlined in the Mode Parameter Pages’ figures or tables and are not described in the Field Description tables.

5.12.5 Unit Attention Condition Page (00h)

Automatic Write Reallocation Enable. When the value is 1, it causes the drive to automatically reallocate bad sectors encountered during a write operation. If it succeeds in replacing the bad sector, the drive adds the revectored sector’s Logical Block Number to the Grown Defect List.

When AWRE is 0, the drive does not automatically reallocate bad sectors encountered during a write operation.

Automatic Read Reallocation Enable. When the value is 1, it causes the drive to automatically reallocate bad sectors encountered during a read operation. If it succeeds in replacing the bad sector, the drive adds the revectored sector’s Logical Block Number to the Grown Defect List. Reallocation is done only when the drive is able to recover the sector’s data unless the Reallocate Uncorrected Errors bit of the Maxtor (Vendor) Special Function Control Page is set.

When ARRE is 0, the drive does not automatically reallocate bad sectors encountered during a read operation. See also Maxtor-Unique Page 39h (RUEE).

Transfer Block. When the value is 1, the drive sends best-guess information to the initiator when it encounters a defective sector whose data cannot be fully recovered.

When the value is 0, data that cannot be fully recovered is not returned to the initiator.

Read Continuous. When the value is 0, the drive attempts error recovery when it encounters an error. When the value is 1, the drive suppresses error recovery. The drive ignores any val-

ue placed in this field.

Post Error Recovery. When the value is 0, the drive returns a GOOD status in cases where error recovery is invoked and successful.

When the value is 1, the drive returns a CHECK CONDITION status for recovered errors, sets the sense key to RECOVERED ERROR, and posts the appropriate additional sense key.

Disable Correction. When the value is 0, ECC correction is applied as a means of recovering erred data. On write operations, a valid ECC is written to each data sector regardless of the value in the DCR bit.

When the value is 1, Firmware ECC correction only is disabled (but not retries or reads), and ECC errors greater than hardware correctable cannot be corrected.

4 Specifies the number of retries attempted for a failed read operation.

value less than the default value can cause an otherwise correctable error to be reported as uncorrectable. If the initiator specifies a value larger than the default value, the drive automatically rounds down the number to the default value. A value of 0 causes the drive to use the default value. The drive ignores any value placed in this field.

The Buffer Full Ratio indicates how full the buffer should be prior to requesting an interconnect tenancy. Applies to READ operations only. The default of 0 indicates to the drive that it should use its default ratio.

The Buffer Empty Ratio indicates how full the buffer should be prior to requesting an interconnect tenancy. Applies to READ operations only. The default of 0 indicates to the drive that it should use its default ratio. Not supported by the drive.

The Bus Inactivity Limit indicates the maximum duration of any interconnect tenancy during which no data is transferred. Not supported by the drive.

The Disconnect Time Limit specifies the minimum time, in 100 microsecond increments, that the drive waits after releasing the SCSI bus before reselecting. The drive supports a maximum value of 0xFF. Values greater than 0xFF are treated as 0xFF. The default value of 0 indicates that the drive can reslect immediately after releasing the bus.

The Connect Time Limit indicates the maximum duration of a single interconnect tenancy. Not supported by the drive.

The Maximum Burst Size specifies the maximum amount of data that the drive will transfer during a data phase before disconnecting from the bus, assuming it was given the disconnect privilege. This value is expressed in increments of data sectors (that is, a value of 1 indicates 512 bytes, a value of 2 indicates 1024 bytes). The default value of 0 indicates that there is no limit on the amount of data transferred per connection. This

field is reserved for the SCSI-1/CCS operating mode.
