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 DiamondMax2160 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.

DIAMONDMAX1750INTRODUCTION  
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.

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.

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.

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.

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:

1 Attach an available IDE interface connector to J1 (see Figure 4-8 below) on the Maxtor hard drive.  
This connector is keyed and will only fit in one orientation. Do not force the connector.  
The striped or colored edge of the IDE interface cable indicates pin 1. Pin 1 on the IDE interface cable should  
match pin 1 on the drive connector. On the Maxtor hard drive, pin 1 is closest to the power connector.

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.  
A
Turn the system ON. During the system start-up sequence, run the SETUP (BIOS) program or similar  
commands to access the system BIOS.  
Note: Newer systems will typically display a message (e.g., press DEL to Enter Setup) identifying how to  
access the SETUP (BIOS) program.  
B
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.  
2
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.

based on 109 or 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.  
C
After the drive parameters are entered, follow the SETUP program procedures to save the settings and exit  
the SETUP program. After changing BIOS settings, saving the values and exiting, the SETUP program  
should force the system to re-boot.  
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

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

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:  
I/O PORT

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:

ID Not Found – Either a matching ID field not found, or a CRC error occurred.  
Aborted Com m and – Invalid commands, write fault, no seek complete, or drive not ready.  
Track 0 Error – Track 0 was not found during execution of a Restore command.  
Address Mark Not Found – The Address Mark could not be found after an ID match.  
Fe a t u re s Re g is t e r

HOST SOFTWAREINTERFACE  
S e c t o r Co u n t Re g is t e r  
Holds the number of sectors to be sent during a Read or Write command, and the number of sectors per  
track during a Format command. A value of zero in this register implies a transfer of 256 sectors. A multi-  
sector operation decrements the Sector Count register. If an error occurs during such an operation, this  
register contains the remaining number of sectors to be transferred.  
S e c t o r Nu m b e r Re g is t e r  
Holds the starting sector number for any disk operation. The register is updated as each sector is processed in  
a multi-sector operation.  
Cylin d e r Nu m b e r Re g is t e rs  
Two 8-bit Cylinder Number registers (Low and High) specify the starting cylinder for disk operation.  
De vic e /He a d Re g is t e r  
Used to specify the drive and head number to be operated on during any disk operations. Within the  
context of a Set Parameters command, this register specifies the maximum number of heads on the drive.

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:

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:  
1.  
2.  
3.  
4.  
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:  
1.  
2.  
3.  
DRQ is never set,  
No data is transferred back to the host and  
The long bit is not valid.  
7 – 2  
INTERFACECOMMANDS  
Re a d DMA  
Multi-word DMA  
Identical to the Read Sector(s) command, except that  
1.  
2.  
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  
3.  
The drive issues only one interrupt per command to indicate that data transfer has  
terminated and status is available.  
Ultra DMA  
With the Ultra DMA Read protocol, the control signal (DSTROBE) that latches data from DD(15:0) is  
generated by the devices which drives the data onto the bus. Ownership of DD(15:0) and this data strobe  
signal are given DSTROBE to the drive during an Ultra DMA data in burst.  
During an Ultra DMA Read burst, the drive always moves data onto the bus, and, after a sufficient time to  
allow for propagation delay, cable settling, and setup time, the sender shall generate a DSTROBE edge to  
latch the data. Both edges of DSTROBE are used for data transfers.  
Any unrecoverable error encountered during execution of a Read DMA command terminates data transfer  
after the transfer of all sectors prior to the sector where the error was detected. The sector in error is not  
transferred. The drive generates an interrupt to indicate that data transfer has terminated and status is  
available. The error posting is identical to the Read Sector(s) command.  
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:  
1.  
2.  
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:  
1.  
2.  
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.  
7 – 3  
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.  
7 – 4  
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:  
1.  
2.  
3.  
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.

not executed.  
Id le Im m e d ia t e – 9 5 h /E1 h  
Spin up and do not change time out value. This command will spin up the spin motor if the drive is spun

S t a n d b y – 9 6 h /E2 h  
Spin down and change time out value. This command will spin the drive down and cause the drive to enter  
the STANDBY MODE immediately. If the drive is already spun down, the spin down sequence is not  
executed. A non-zero value placed in the sector count register will enable the Automatic Power Down  
sequence. The timer will begin counting down when the drive returns to the IDLE MODE. A value of zero  
placed in the sector count register will disable the Automatic Power Down sequence.

Spin up and change time out value. This command will spin-up the spin motor if the drive is spun-down.  
If the drive is already spinning, the spin up sequence is not executed. A non-zero value placed in the Sector

Ch e c k P o w e r Mo d e – 9 8 h /E5 h  
This command returns a code in the Sector Count register that determines the current Power Mode status of  
the drive. If the drive is in, going to, or recovering from the STANDBY MODE the drive sets the Sector  
Count register to OOh. If the drive is in the IDLE MODE or ACTIVE MODE, the drive sets the Sector  
Count register to FFh.  
S e t S le e p Mo d e – 9 9 h /E6 h  
This command will spin the drive down and cause the drive to enter the SLEEP MODE immediately. If the  
drive is already spun down, the spin down sequence is not executed.  
Note: The only way to recover from SLEEP MODE is with a software reset or a hardware reset.  
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.

INTERFACECOMMANDS  
When enabling the Automatic Power Down sequence, the value placed in the Sector Count register is  
multiplied by five seconds to obtain the Time-out Interval value. If no drive commands are received from

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.

S e e k  
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.

Note: If a slave drive fails diagnostics, the master drive ORs 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 ORs 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  
Register  
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  
register. The sub-commands and their respective codes are:  
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.

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

Repairs to any DiamondMax™ 2160 drive should be made only at an authorized Maxtor repair facility.  
Any unauthorized repairs or adjustments to the drive void the warranty.  
To consistently provide our customers with the best possible products and services, Maxtor developed the  
Total Customer Satisfaction (TCS) program. Through the ongoing TCS process, Maxtor employees take  
direct responsibility for every customer’s level of satisfaction – with Maxtor technology, price, quality,  
delivery, service and support.  
No Qu ib b le ® S e rvic e  
Another TCS feature is Maxtor’s No Quibble® Service policy. By minimizing paperwork and processing,  
No Quibble Service dramatically cuts the turnaround time normally required for repairs and returns.  
Here’s how it works:  
1. Customer calls 1-800-2MAXTOR for a Return Material Authorization (RMA) number  
and provides a credit card number,  
2. Maxtor ships a replacement drive within 48 hours, and  
3. Customer returns the original drive and credit card draft is destroyed.
