DIAMONDMAX1750–INTRODUCTION

SECTION 1

In t ro d u c t io n

Ma xt o r Co rp o ra t io n

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.

P r o d u c t s

Maxtor’s products meet those demanding storage capacity requirements with room to spare. They feature

proven compatibility and reliability. While DiamondMax™ 2160 is the latest addition to our family of high

performance desktop hard drives, the DiamondMax™ 1750 and CrystalMax™ 1080 series hard drives deliver

industry-leading capacity, performance and value for many PC applications.

S u p p o r t

No matter which capacity, all Maxtor hard drives are supported by our commitment to total customer

satisfaction and our No Quibble^®Service guarantee. One call – or a visit to our home page on the Internet

(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.

DIAMONDMAX1750–INTRODUCTION

Co n ve n t io n s

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

Ke y Wo rd s

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).

N u m b e r in g

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.

S ig n a l Co n ve n t io n s

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.

PRODUCTDESCRIPTION

P ro d u c t Fe a t u re s

Fu n c t io n a l / In t e rfa c e

Maxtor DiamondMax™ 2160 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.

Zo n e De n s it y Re c o rd in g

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.

Re a d /Writ e Mu lt ip le Mo d e

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.

Ult ra DMA - Mo d e 2

Maxtor DiamondMax 2160 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.

Mu lt i-w o rd DMA (EIS A Typ e B) - Mo d e 2

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

S e c t o r Ad d re s s Tra n s la t io n

All DiamondMax 2160 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 2160 drives power-up in a translate mode:

PRODUCTDESCRIPTION

Lo g ic a l Blo c k Ad d re s s in g

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

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

(1)

(2)

where

HSCA = Host Sector Address, HHDA = Host Head Address

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.

De fe c t Ma n a g e m e n t Zo n e (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.

Au t o m a t ic P a rk a n d Lo c k Op e ra t io n

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.

PRODUCTDESCRIPTION

Ca c h e Ma n a g e m e n t

Bu ffe r S e g m e n t a t io n

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.

Re a d -Ah e a d Mo d e

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, read-

ahead mode continues without interruption and the host transfer begins immediately.

Au t o m a t ic Writ e Re a llo c a t io n (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.

Writ e Ca c h e S t a c k in g

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.

PRODUCTDESCRIPTION

Ma jo r HDA Co m p o n e n t s

Drive Me c h a n is m

A brush-less DC direct drive motor rotates the spindle at 5,200 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.

Ro t a ry Ac t u a t o r

All DiamondMax™ 2160 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.

Re a d /Writ e Ele c t ro n ic s

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.

Re a d /Writ e He a d s a n d Me d ia

Low mass, low force 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 2160 drives.

Air Filt ra t io n S ys t e m

All DiamondMax 2160 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 2160 drives are designed to operate in a typical office

environment with minimum environmental control.

PRODUCTDESCRIPTION

S u b s ys t e m Co n fig u ra t io n

Du a l Drive S u p p o rt

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.

Ca b le S e le c t Op t io n

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.

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.

Ra d ia t e d Ele c t ro m a g n e t ic Fie ld Em is s io n s - EMC Co m p lia n c e

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.

S t a n d a rd Te s t Me t h o d s

Traditional hard drive specifications are open to incorrect interpretation, but MIL-STD test methods accurately

measure how products perform in real-world conditions. These methods have gained worldwide acceptance

since they reflect actual environments, have well-defined test requirements, are easily understood and provide

repeatable results. They objectively demonstrate to our customers the reliable, durable design of Maxtor hard

drives. Each MIL-STD specification provides the basic method and condition information needed for reference

by a knowledgeable Test and Qualification Engineer.

Acoustic specifications such as sound pressure are misleading because the test methods used are not controlled

by recognizable standards. The sound pressure measurement itself is the least meaningful indicator of noise

emissions as it relates to the human ear. The specification of sound power, loudness and sharpness are

considered the most accurate acoustic measurement methodologies recognized by the leading acoustic

measurement experts. ISO 7779, sound power, ISO 532B, loudness and sharpness (proposed ANSI standard by

Eberhard Zwicker) are repeatable test methods providing results reproducible in any properly equipped

acoustic lab.

P re -fo rm a t t e d Drive

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

Im p o rt a n t No t ic e

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.

Ha rd Drive Ha n d lin g P re c a u t io n s

◆ 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.

◆ 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.

Ele c t ro -S t a t ic Dis c h a rg e (ES D)

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:

INSTALLATION

S ys t e m S e t u p

The following procedures are designed for systems using the DOS 5.0 (or higher) or Windows 95 operating

systems. For other operating systems (e.g., OS2^®, UNIX^®, LINUX and Novell NetWare^®), refer to the

operating system user’s manual for the BIOS setting and other installation requirements

S e t t in g t h e BIOS (CMOS )

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 hard drive. To do this, run the system SETUP (BIOS) program.

The SETUP (BIOS) program identifies the system configuration information (e.g., floppy disk drives, hard disk

drives, video, etc.) used by the computer during system boot. This includes the information about what kind

and how many hard drives are attached to the system.

If you are unsure of how to access the system BIOS and/ or program the BIOS settings, refer to the computers

user’s manual for detailed instructions.

WARNING: When entering the settings for the new Maxtor hard drive, be careful not to change any of

the other BIOS settings, or other parts of the system may not work correctly.

Note: Most of the systems with newer BIOS’ (typically with a date of July 1994 or newer), support large

capacity hard drives. It is necessary to determine if the system provides support for large capacity hard drives

before entering the settings, as this affects how to correctly set the BIOS parameters for the Maxtor hard drive.

S e t t h e BIOS (CMOS ) p a ra m e t e rs a s fo llo w s :

IMPORTANT: 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 apeearance of the information on the screens and the location of parameters

within the BIOS. Refer to the system or BIOS manufacturers documentation for the correct procedure to

enter the BIOS setup program for your system.

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.

OncetheSETUP(BIOS)programisactive,dooneofthefollowingtosettheharddriveBIOSparameters.

If the SETUP program provides an “AUTO DETECT” capability, use this feature to detect the

Maxtor hard drive.

Note: After the SETUP program has detected the hard drive, verify that the Logical

Block Addressing (LBA) mode is enabled for this drive.

If the SETUP program does not provide an “AUTO DETECT” capability, set the drive

parameters as defined in step 2).

Comment: When LBA is enabled, some BIOS programs 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 does not change the capacity of the 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). Select the appropriate UDT for the Maxtor

hard drive and set the cylinder, head and sector values for the model being installed from the

table below.

and the values may be either 0 or the values set by the BIOS. All capacities listed in the parameters table are

based on 10⁹or one million bytes.

Only the values for cylinders, heads and sectors listed in the table must be entered. All other values may be

zero (0). Set the LBA mode to enabled for this drive. 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.

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.

Note: Each BIOS manufacturer uses different methods of identifying the UDT. Newer BIOS’ from all

manufacturers will usually include an entry called “User” or “User 1.” Older BIOS’ vary in the

method used to identify the UDT: AMI = Type 47, Award = Type 47 and Phoenix = Type 48.

S ys t e m Ha n g s Du rin g Bo o t

If the system hangs 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 with capacities larger than

2.1 GB. If this happens, do the following:

INSTALLATION

Install the cylinder reduction jumper (J46) on the drive using the spare jumper shipped across pins J46 and

J48; or, if the drive is installed as a Slave, store the spare jumper across J42 and J44.

If the BIOS was set to AUTO DETECT, boot the system with the MaxBlast installation software diskette

to complete the hard drive installation. If other BIOS settings were used, access the system BIOS SETUP

program and set the BIOS parameters to a User Definable Type with 4,092 cylinders, 16 heads and 63

sectors per track for the Maxtor hard drive. Then boot the system with the MaxBlast installation software

diskette to complete the hard drive installation.

IMPORTANT: When jumper J46 is installed, the Maxtor hard drive must be prepared using the

MaxBlast installation software.

Ha rd Drive P re p a ra t io n

To complete the Maxtor hard drive installation, the drive must be partitioned and formatted.

Boot the system to the bootable MaxBlast software installation diskette received with the hard drive and

proceed to step 2.

The MaxBlast installation software will load and the first screen of the program will display. Complete the

information in the System Configuration Information table and follow the on-screen prompts to complete

the hard drive installation.To complete the installation of the Maxtor hard drive, the drive must be

partitioned and formatted.

S ys t e m /Drive In fo rm a t io n

The first time MaxBlast installation software is run, it will display information in a format similar to the System

Configuration Information table. Subsequent executions start at the main menu and allow the user to

optionally display this information.

The information in the System Configuration table must be completed for your records. This information

will be requested by the Maxtor Technical Assistance representative in the event that you call for assistance.

The Maxtor hard drive model number and serial number are also located on the top cover label of the hard

HOST SOFTWAREINTERFACE

SECTION 6

Ho s t S o ft w a re In t e rfa c e

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.

Ta s k File Re g is t e rs

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:

Da t a Re g is t e r

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.

Erro r Re g is t e r

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:

Re s e t Ha n d lin g

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

In t e rru p t Ha n d lin g

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.

Re a d Co m m a n d s

Re a d S e c t o r(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:

The data field is read into the sector buffer.

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

The DRQ bit is set.

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.

Re a d Ve rify S e c t o r(s )

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

DRQ is never set,

No data is transferred back to the host and

The long bit is not valid.

INTERFACECOMMANDS

Re a d DMA

Multi-word DMA

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

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

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

and

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.

Re a d Mu lt ip le

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:

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

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:

Before the Set Multiple Mode command has been executed, or

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.

INTERFACECOMMANDS

S e t Mu lt ip le Mo d e

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.

Writ e Co m m a n d s

Writ e S e c t o r(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.

Writ e Ve rify S e c t o r(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.

Writ e S e c t o r Bu ffe r

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.

INTERFACECOMMANDS

Writ e Mu lt ip le

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.

Writ e DMA

Multi-word DMA

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

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

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

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.

De fa u lt P o w e r-o n Co n d it io n

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.

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

In it ia lize Drive P a ra m e t e rs

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.

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.

Fo rm a t Tra c k

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.

Exe c u t e Drive Dia g n o s t ic

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.

DESCRIPTION

No error detected

Master drive failed

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.

S .M.A.R.T. Co m m a n d S e t

Exe c u t e 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

4Fh

C2h

Cylinder Low (1F4h)

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 sub-

command-specific code to the device’s Features register before writing the command code to the command

D0h

D1h

D2h

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

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

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

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

Enable/Disable Autosave

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.

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

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.
