2.1 PRODUCT DESCRIPTION

Maxtor drive leadership continues wit the DiamondMax Plus 8 drive - the first singlehead, single platter, 7200RPM product. DiamondMax Plus 8 drives combine performance and value making a perfect choice for mainstream consumer or commercial/business desktop users.

DiamondMax Plus 8 drives use the Ultra ATA/133 interface, the fastest desktop interface with maximum data transfer rates of 133MB/second.

Fluid dynamic bearing (FDB) motors minimize drive acoustics, allowing the drive to operate with low sound output. DiamondMax Plus 8 is designed for higher reliability. The drive’s inner diameter load/unload ramp locks the recording head into a protective carrier to cradle the head during shipment and any other time the drive is not in operation.

DiamondMax Plus 8 drives deliver high reliability and data integrity using Maxtor developed Shock Protection System (SPS) and Data Protection System (DPS). SPS and DPS give the user enhanced protection against both operating and non-operating shock and verify essential functions in seconds to minimize costly drive returns.

4.3.1 Cable Select (CS) Jumper

When a Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drive and another ATA hard disk drive are daisy-chained together, they can be configured as Master or Slave either by the CS or DS jumpers. To configure the drive as a Master or Slave with the CS feature, the CS jumper is installed (1). The drive's position on the 80 conductor Ultra ATA data cable then determines whether the drive is a Master (Device

0) or a Slave (Device 1). If the drive is connected to the end of the Ultra (cable Select) data cable the drive is a Master. If the drive is connected to the middle connection it is set as a Slave.

Once you install the CS jumper, the drive is configured as a Master or Slave by the state of the Cable Select signal: pin 28 of the ATA bus connector. Please note that pin 28 is a vendor-specific pin that Maxtor is using for a specific purpose. More than one function is allocated to CS, according to the ATA CAM specification (see reference to this specification in Chapter 1). If pin 28 is a 0 (grounded), the drive is configured as a Master. If it is a 1 (high), the drive is configured as a Slave. In order to configure two drives in a Master/Slave relationship using the CS jumper, you need to use a cable that provides the proper signal level at pin 28 of the ATA bus connector. This allows two drives to operate in a Master/Slave relationship according to the drive cable placement.

The Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drives are shipped from the factory as a Master (Device 0 - CS jumper installed). To configure a drive as a Slave (Device 1- DS scheme), the CS jumper must be removed. In this configuration, the spare jumper removed from

4-6 DiamondMax Plus8 20/30/40GB AT

the CS position may be stored on the PK jumper pins.

4.3.2 Drive Select (DS) Jumper

You can also daisy-chain two drives on the ATA bus interface by using their Drive Select (DS) jumpers. To use the DS feature, the CS jumper must not be installed.

To configure a drive as the Master (Device 0), a jumper must be installed on the DS pins.

Note: The order in which drives are connected in a daisy chain

has no significance.

4.3.3 Master Jumper configuration

In combination with the current DS or CS jumper settings, the Slave Present (SP) jumper can be implemented if necessary as follows:

Note: The CS position doubles as the Slave present on this

drive.

• When the drive is configured as a Master or CS jumper installed, and the Cable Select signal is set to (0), adding an additional jumper (both jumpers DS and CS now installed) will indicate to the drive that a Slave drive is present. This Master with Slave Present jumper configuration should be installed on the Master drive only if the Slave drive does not use the Drive Active/Slave Present (DASP–) signal to indicate its presence.

Installation

(DS jumper installed

4.3.4 Jumper Parking (PK) Position

The PK position is used as a holding place for the jumper for a slave drive in systems that do not support Cable Select. The pins used for the parking position are vendor unique.

4.3.5 Alternate Capacity (AC)

For user capacities below 66,055,248 sectors (32GB), inserting the AC jumper limits the Number of Cylinders field 1 to a value of 16,383, as reported in IDENTIFY DEVICE data word. This allows software drivers to determine that the actual capacity is larger than indicated by the maximum CHS, requiring LBA addressing to use the full capacity.

CAUTION: The PCB is very close to the mounting holes. Do not exceed the specified penetration for the

mounting screws. The specified screw penetration allows full use of the mounting hole threads, while avoiding damaging or placing unwanted stress on the PCB. Figure 4-7 specifies the minimum clearance between the PCB and the screws in the mounting holes.

The Maxtor hard drive design allows greater shock tolerance than that afforded by larger, heavier drives. The drive may be mounted in any attitude using four size 6-32 screws with 3 mm maximum penetration and a maximum torque of 5-inch pounds. Allow adequate ventilation to the drive to ensure reliable operation.

On the Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drives, the ATA bus interface cable connector (J1, section C) is a 40-pin Universal Header, as shown in Figure 4-7.

To prevent the possibility of incorrect installation, the connector has been keyed by removing Pin 20. This ensures that a connector cannot be installed upside down.

See Chapter 5, “ATA Bus Interface and ATA Commands,” for more detailed information about the required signals. Refer to Table 5-1 for the pin assignments of the ATA bus connector (J1, section C).

4.6 FOR SYSTEMS WITH A MOTHERBOARD ATA ADAPTER

You can install the Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drives in an AT-compatible system that contains a 40-pin ATA bus

4-12 DiamondMax Plus8 20/30/40GB AT

connector on the motherboard.

To connect the drive to the motherboard, use a 40 conductor ribbon cable (80 conductor ribbon cable if using Ultra ATA/66/100 or /133 drive) 18 inches in length or shorter. Ensure that pin 1 of the drive is connected to pin 1 of the motherboard connector.

4.7 FOR SYSTEMS WITH AN ATA ADAPTER BOARD

To install the Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drive in an AT-compatible system without a 40-pin ATA bus connector on its motherboard, you need a third-party IDE-compatible adapter board.

4.7.1 Adapter Board Installation

Carefully read the manual that accompanies your adapter board before installing it. Make sure that all the jumpers are set properly and that there are no address or signal conflicts. You must also investigate to see if your AT-compatible system contains a combination floppy and hard disk controller board. If it does, you must disable the hard disk drive controller functions on that controller board before proceeding.

Installation

Once you have disabled the hard disk drive controller functions on the floppy/hard drive controller, install the adapter board. Again, make sure that you have set all jumper straps on the adapter board to avoid addressing and signal conflicts.

Note: For Sections 4.7 and 4.8, power should be turned off

on the computer before installing the drive.

DiamondMax Plus8 20/30/40GB AT 4-13

Installation

4.7.1.1 Connecting the Adapter Board and the Drive

Use a 40-pin ribbon cable to connect the drive to the board. See Figure 4-8. To connect the drive to the board:

1. Insert the 40-pin cable connector into the mating connector of the adapter board. Make sure that pin 1 of the connector matches with pin 1 on the cable.

2. Insert the other end of the cable into the header on the drive. When inserting this end of the cable, make sure that pin 1 of the cable connects to pin 1 of the drive connector.

3. Secure the drive to the system chassis by using the mounting screws, as shown in Figure 4-9.

4.8 TECHNIQUES IN DRIVE CONFIGURATION

4.8.1 The 528-Megabytes Barrier

Older BIOS that only support Int 13 commands for accessing ATA drives through DOS based operating systems will be limited to use only 1024 cylinders. This will reduce the effective capacity of the drive to 528Mbytes.

Whenever possible the Maxtor DiamondMax Plus8 20/30/40GB AT drive should be used on systems that support LBA translation to ensure the use of the entire capacity of the disk drive. If that is not possible the following are some techniques that can be used to overcome this barrier.

DiamondMax Plus8 20/30/40GB AT 4-15

Installation

• Use a third party software program that translates the hard

drive parameters to an acceptable configuration for MS-DOS.

• Use a hard disk controller that translates the hard drive

parameters to an appropriate setup for both MS-DOS and the computer system’s ROM-BIOS.

• Insert the Alternate Capacity (AC) jumper on the drive (see

Section 4.3.5).

4.8.2 The 8.4-Gigabytes Barrier

Newer BIOS’s allow users to configure disk drives to go beyond the 528MB barrier by using several BIOS translation schemes. However, while using these translations the BIOS using Int 13 functions are limited to 24 bits of addressing which results in another barrier at the

8.4GB capacity.

To overcome this barrier a new set of Int 13 extensions are being implemented by most BIOS manufacturers. The new Int 13 extension allows for four words of addressing space (64 bits) resulting in 9.4 Terrabytes of accessible space.

Whenever possible the Maxtor DiamondMax Plus8 20/30/40GB AT drive should be used on systems with BIOS that support Int 13 extensions. If that is not possible the following are some techniques that can be used to overcome this barrier: Use a third party software that supplements the BIOS and adds Int 13 extension support.

• Obtain a BIOS upgrade from the system board manufacturer.

Many system board manufacturers allow their BIOS to be upgraded in the field using special download utilities. Information on BIOS upgrades can be obtained on the System Board Customer Service respective web sites on the Internet.

• Insert the Alternate Capacity (AC) jumper on the drive (see

Section 4.3.5).

4.8.3 Operating system limitations

Most popular operating systems available today have additional limitations which affect the use of large capacity drives. However, these limitations can not be corrected on the BIOS and it is up to the operating system manufacturers to release improved versions to address these problems.

The most popular operating systems available today, DOS and Win 95, use a File Allocation Table (FAT) size of 16 bits which will only support partitions up to 2.1GB. A newer release of Win 95 called OSR2 with a 32 bit FAT has been released to system manufacturers only. This new FAT size table will support partitions of up to 2.2 Terrabytes.

4.9 SYSTEM STARTUP AND OPERATION

Once you have installed the Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drive, and adapter board (if required) in the host system, you are ready to partition and format the drive for operation. To set up the drive correctly, follow these steps:

1. Power on the system.

2. Run the SETUP program. This is generally on a Diagnostics or Utilities disk, or within the system’s BIOS. Some system BIOS have an auto-detecting feature making SETUP unnecessary.

3. Enter the appropriate parameters.

The SETUP program allows you to enter the types of optional hardware installed—such as the hard disk drive type, the floppy disk drive capacity, and the display adapter type. The system’s BIOS uses this information to initialize the system when the power is switched on. For instructions on how to use the SETUP program, refer to the system manual for your PC.

Installation

During the AT system CMOS setup, you must enter the drive type for the Maxtor DiamondMax Plus8 hard disk drives. The drive supports the translation of its physical drive geometry parameters such as cylinders, heads, and sectors per track to a logical addressing mode. The drive can work with different BIOS drive-type tables of the various host systems.

You can choose any drive type that does not exceed the capacity of the drive. Table 4-3 gives the logical parameters that provide the maximum capacity on the Maxtor DiamondMax Plus8 family of hard disk drives.

Table 4-3 Logical Addressing Format

MODELS CYL HD SPT MAX LBA CAPACITY

6E020L0 40,395 16 63 40,718,160 20GB

6E030L0 59,582 16 63 60,058,656 30GB

6E040L0 79,656 16 63 80,293,248 40GB

Note: *Capacity may be restricted to 8.4GB (or less) due to

system BIOS limitations. Check with your system manufacturer to determine if your BIOS supports LBA Mode for hard drives greater than 8.4GB. Default logical cylinders is limited to 16,383 as per the ATA-4 specifications.

To match the logical specifications of the drive to the drive type of a particular BIOS, consult the system’s drive-type table. This table

DiamondMax Plus8 20/30/40GB AT 4-17

Installation

specifies the number of cylinders, heads, and sectors for a particular drive type.

You must choose a drive type that meets the following requirements:

For the 20, 30 and 40 GB:

Logical Cylinders x Logical Heads x Logical Sectors/Track x 512 = 8,455,200,768

4. Boot the system using the operating system installation disk— for example, MS-DOS—then follow the installation instructions in the operating system manual.

ATA BUS INTERFACE AND ATA COMMANDS

This chapter describes the interface between DiamondMax Plus8 hard disk drives and the ATA bus. The commands that are issued from the host to control the drive are listed, as well as the electrical and mechanical characteristics of the interface.

5.1 INTRODUCTION

Maxtor DiamondMax Plus8 hard disk drives use the standard ATA/ATAPI interface. Support of various options in the standard are explained in the following sections.

5.2 MECHANICAL INTERFACE

5.2.1 Signal Cable and Connector

The Maxtor DiamondMax Plus8 hard disk drive contains a 40-pin unitized connector for both signal and power connections as well as configuration jumpers. The dimensions and specifications of the unitized connector comply with Annex. A in the ATA/ATAPI standard.

The Maxtor DiamondMax Plus8 drives require the use of an 80 conductor cable (ATA/ATAPI-6, Annex. A, Figure A.4 and description) to support the drive’s Ultra DMA capability.

5.3 ELECTRICAL INTERFACE

5.3.1 ATA Bus Interface

5.3.1.1 Electrical Characteristics

Signals on the ATA interface are assigned to connector pins according to Annex. A in the ATA/ATAPI-6 standard for the 80 conductor cable assembly. The signaling protocol complies with clause 9 and signal timing complies with clause 10 of the standard.

The Maxtor DiamondMax Plus8 hard disk drives support all Ultra DMA Data Transfer modes (0 - 5) defined in the ATA/ATAPI-6 standard. In addition, these drives support Mode 6, and can send and receive data at the full 133MB/s transfer rate.

Hosts may assert the RESET- signal for longer than the minimum. When power is applied with RESET- asserted, the Maxtor DiamondMax Plus8 disk media will not begin to spin up until RESET- is negated. This may reduce maximum current

GLOSSARY

ACCESS – (v) Read, write, or update

information on some storage medium, such as a disk. (n) One of these operations.

ACCESS TIME – The interval between the time a request for data is made by the system and the time the data is available from the drive. Access time includes the actual seek time, rotational latency, and command processing overhead time. See also seek, rotational latency, and overhead.

ACTUATOR – Also known as the positioner. The internal mechanism that moves the read/write head to the proper track. The Maxtor actuator consists of a rotary voice coil and the head mounting arms. One end of each head mounting arm attaches to the rotor with the read/write heads attached at the opposite end of each arm. As current is applied to the rotor, it rotates, positioning the heads over the desired cylinder on the media.

AIRLOCK (all Maxtor drives).

ALLOCATION – The process of assigning particular areas of the disk to particular files. See also allocation unit.

ALLOCATION UNIT – An allocation unit, also known as a cluster, is a group of sectors on the disk that can be reserved for the use of a particular file.

AVERAGE SEEK TIME – The average time it takes for the read/write head to move to a specific location. To compute the average seek time, you divide the time it takes to complete a large number of random seeks all over the disk by the number of seeks performed.

BACKUP – A copy of a file, directory,

or volume on a separate storage device from the original, for the purpose of retrieval in case the original is accidentally erased, damaged, or destroyed.

AIRLOCK – A patented Maxtor feature that ensures durable and reliable data storage. Upon removal of power from the drive for any reason, the read/write heads automatically park and lock in a non data area called the landing zone. AIRLOCK allows the drive to withstand high levels of non-operating shock. When power is applied to the drive, airflow created from the spinning disks causes the AIRLOCK arm to swing back and unlock the actuator, allowing the heads to move from the landing zone. Upon power down, the AIRLOCK swings back to the locked position, locking the heads in the landing zone. A park utility is not required to park the heads on drives equipped with

BAD BLOCK – A block (usually the size of a sector) that cannot reliably hold data because of a media flaw or damaged format markings.

BAD TRACK TABLE – A label affixed to the casing of a hard disk drive that tells which tracks are flawed and cannot hold data. The listing is typed into the low-level formatting program when the drive is being installed. Because Maxtor disk drive’s defect-management scheme handles all such flaws automatically, there is no need to concern yourself with bad track tables.

BIT – Abbreviation for binary digit. A binary digit may have one of two values—1 or 0. This contrasts with a

Maxtor DiamondMax Plus8 20/30/40GB AT G-1

Glossary

decimal digit, which may have a value from 0 to 9. A bit is one of the logic 1or logic 0 binary settings that make up a byte of data. See also byte.

BLOCK – A sector or group of sectors. By default, a block of data consists of 512 bytes.

BPI – Abbreviation for bits per inch. A measure of how densely information is packed on a storage medium. Flux changes per inch is also a term commonly used in describing storage density on a magnetic surface.

BUFFER – An area of RAM reserved for temporary storage of data that is waiting to be sent to a device that is not yet ready to receive it. The data is usually on its way to or from the disk drive or some other peripheral device.

BUS – The part of a chip, circuit board, or interface designed to send and receive data.

BYTE – The basic unit of computer memory, large enough to hold one character of alphanumeric data. Comprised of eight bits. See also bit.

CACHE – Random-access memory

used as a buffer between the CPU and a hard disk. Information more likely to be read or changed is placed in the cache, where it can be accessed more quickly to speed up general data flow.

CAPACITY – The amount of information that can be stored on a disk drive. The data is stored in bytes, and capacity is usually expressed in megabytes.

CDB – Command Descriptor Block. The SCSI structure used to communicate requests from an initiator (system) to a target (drive).

CLEAN ROOM – An environmentally

controlled dust-free assembly or repair facility in which hard disk drives are assembled or can be opened for internal servicing.

CLUSTER – A group of sectors on a disk drive that is addressed as one logical unit by the operating system.

CONTROLLER – Short form of disk controller. The chip or complete circuit

that translates computer data and commands into a form suitable for use by the disk drive.

CONTROLLER CARD – An adapter holding the control electronics for one or more hard disks, usually installed in a slot in the computer.

CPU – Acronym for Central Processing Unit. The microprocessor chip that

performs the bulk of data processing in a computer.

CRC – Acronym for Cyclic Redundancy Check. An error detection code that is

recorded within each sector and is used to see whether parts of a string of data are missing or erroneous.

CYLINDER – On a disk drive that has more than one recording surface and heads that move to various tracks, the group of all tracks located at a given head position. The number of cylinders times the number of heads equals the number of tracks per drive.

DATA SEPARATOR – On a disk drive

that stores data and timing information in an encoded form, the circuit that extracts the data from the combined data and clock signal.

DEDICATED SERVO – A surface separate from the surface used for data that contains only disk timing and positioning information and contains no data.

DEFECT MANAGEMENT – A method that is implemented to ensure long

G-2 Maxtor DiamondMax Plus8 20/30/40GB AT

Glossary

term data integrity. Defect management eliminates the need for user defect maps. This is accomplished by scanning the disk drives at the factory for defective sectors. Defective sectors are deallocated prior to shipment. In addition, during regular use, the drive continues to scan and compensate for any new defective sectors on the disk.

DISK – In general, any circular-shaped data-storage medium that stores data on the flat surface of the platter. The most common type of disk is the magnetic disk, which stores data as magnetic patterns in a metal or metal-oxide coating. Magnetic disks come in two forms: floppy and hard. Optical recording is a newer disk technology that gives higher capacity storage but at slower access times.

DISK CONTROLLER – A plug-in board, or embedded circuitry on the drive, that passes information to and from the disk. The Maxtor disk drives all have controllers embedded on the drive printed-circuit board.

DISKWARE – The program instructions and data stored on the disk for use by a processor.

DMA – Acronym for direct memory access. A process by which data

moves directly between a disk drive (or other device) and system memory without passing through the CPU, thus allowing the system to continue processing other tasks while the new data is being retrieved.

DRIVE – Short form of disk drive.

DRIVE GEOMETRY – The functional

dimensions of a drive in terms of the number of heads, cylinders, and sectors per track. See also logical format.

information encoded along with the disk data. The controller uses the extra information to check for data errors, and corrects the errors when possible.

EMBEDDED SERVO – A timing or location signal placed on the disk’s surface on the tracks that also store data. These signals allow the actuator to fine-tune the position of the read/write heads.

ENCODING – The protocol by which particular data patterns are changed prior to being written on the disk surface as a pattern of On and Off or 1 and 0 signals.

EXTERNAL DRIVE – A drive mounted in an enclosure separate from the PC or computer system enclosure, with its own power supply and fan, and connected to the system by a cable.

FAT – Acronym for file allocation table.

A data table stored on the outer edge of a disk that tells the operating system which sectors are allocated to each file and in what order.

FCI – Acronym for flux changes per inch. See also BPI.

FILE SERVER – A computer that provides network stations with controlled access to shareable resources. The network operating system is loaded on the file server, and most shareable devices (disk subsystems, printers) are attached to it. The file server controls system security and monitors station-to-station communications. A dedicated file server can be used only as a file server while it is on the network. A non dedicated file server can be used simultaneously as a file server and a workstation.

ECC – Acronym for error correction

code. The recording of extra verifying

FLUX DENSITY – The number of magnetic field patterns that can be stored in a given length of disk surface. The number is usually stated as flux

Maxtor DiamondMax Plus8 20/30/40GB AT G-3

Glossary

changes per inch (FCI), with typical values in the thousands.

FLYING HEIGHT – The distance between the read/write head and the disk surface caused by a cushion of air that keeps the head from contacting the media. Smaller flying heights permit more dense storage of data, but require more precise mechanical designs.

FORMAT – To write onto the disk surface a magnetic track pattern that specifies the locations of the tracks and sectors. This information must exist on a disk before it can store any user data. Formatting erases any previously stored data.

FORMATTED CAPACITY – The amount of room left to store data on the disk after the required space has been used to write sector headers, boundary definitions, and timing information generated by a format operation. All Maxtor drive capacities are expressed in formatted capacity.

FORM FACTOR – The physical outer dimensions of a device as defined by industry standard. For example, most Maxtor disk drives use a 3 1/2-inch form factor.

HARD DISK – A type of storage

medium that retains data as magnetic patterns on a rigid disk, usually made of an iron oxide or alloy over a magnesium or aluminum platter. Because hard disks spin more rapidly than floppy disks, and the head flies closer to the disk, hard disks can transfer data faster and store more in the same volume.

HARD ERROR – A repeatable error in disk data that persists when the disk is reread, usually caused by defects in the media surface.

HEAD – The tiny electromagnetic coil and metal pole piece used to create and read back the magnetic patterns (write and read information) on the media.

HIGH-CAPACITY DRIVE – By industry conventions typically a drive of 1 gigabytes or more.

HIGH-LEVEL FORMATTING – Formatting performed by the operating system’s format program. Among other things, the formatting program creates the root directory and file allocation tables. See also low-level formatting.

HOME – Reference position track for re-calibration of the actuator, usually the outer track (track 0).

GIGABYTE (GB) – One billion bytes (one thousand megabytes).

GUIDE RAILS – Plastic strips attached to the sides of a disk drive mounted in an IBM AT and compatible computers so that the drive easily slides into place.

HALF HEIGHT – Term used to describe

a drive that occupies half the vertical space of the original full size 5 1/4-inch drive. 1.625 inches high.

G-4 Maxtor DiamondMax Plus8 20/30/40GB AT

HOST ADAPTER – A plug-in board that forms the interface between a particular type of computer system bus and the disk drive.

INITIALIZE – See low level formatting.

INITIATOR – A SCSI device that

requests another SCSI device to perform an operation. A common example of this is a system requesting data from a drive. The system is the initiator and the drive is the target.

INTERFACE – A hardware or software protocol, contained in the electronics

Glossary

of the disk controller and disk drive, that manages the exchange of data between the drive and computer.

INTERLEAVE – The arrangement of sectors on a track. A 1:1 interleave arranges the sectors so that the next sector arrives at the read/write heads just as the computer is ready to access it. See also interleave factor.

INTERLEAVE FACTOR – The number of sectors that pass beneath the read/write heads before the next numbered sector arrives. When the interleave factor is 3:1, a sector is read, two pass by, and then the next is read. It would take three revolutions of the disk to access a full track of data. Maxtor drives have an interleave of 1:1, so a full track of data can be accessed within one revolution of the disk, thus offering the highest data throughput possible.

INTERNAL DRIVE – A drive mounted inside one of a computer’s drive bays (or a hard disk on a card, which is installed in one of the computer’s slots).

JUMPER – A tiny box that slips over

two pins that protrude from a circuit board. When in place, the jumper connects the pins electrically. Some board manufacturers use Dual In-Line Package (DIP) switches instead of jumpers.

touching the surface in data areas upon power down, adding to the data integrity and reliability of the disk drive.

LATENCY – The period of time during which the read/write heads are waiting for the data to rotate into position so that it can be accessed. Based on a disk rotation speed of 3,662 rpm, the maximum latency time is 16.4 milliseconds, and the average latency time is 8.2 milliseconds.

LOGICAL FORMAT – The logical drive geometry that appears to an AT system BIOS as defined by the drive tables and stored in CMOS. With an installation program like Disk Manager, the drive can be redefined to any logical parameters necessary to adapt to the system drive tables.

LOOK AHEAD – The technique of buffering data into cache RAM by reading subsequent blocks in advance to anticipate the next request for data. The look ahead technique speeds up disk access of sequential blocks of data.

LOW-LEVEL FORMATTING – Formatting that creates the sectors on the platter surfaces so the operating system can access the required areas for generating the file structure. Maxtor drives are shipped with the low-level formatting already done.

LOW PROFILE – Describes drives built to the 3 1/2-inch form factor, which are only 1 inch high.

KILOBYTE (Kb) – A unit of measure

consisting of 1,024 (210) bytes.

LANDING ZONE – A position inside the

disk’s inner cylinder in a non data area reserved as a place to rest the heads during the time that power is off. Using this area prevents the heads from

Maxtor DiamondMax Plus8 20/30/40GB AT G-5

MB – See megabyte.

MEDIA – The magnetic film that is

deposited or coated on an aluminum substrate which is very flat and in the shape of a disk. The media is overcoated with a lubricant to prevent damage to the heads or media during head take off and landing. The media is where the data is stored inside the disk in the form of magnetic flux or polarity changes.

MEGABYTE (MB) – A unit of measurement equal to 1,024 kilobytes, or 1,048,576 bytes except when referring to disk storage capacity.

1 MB = 1,000,000 bytes when referring to disk storage capacity.
