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.   Ma n u a l Org a n iza t io n   This hard disk drive reference manual is organized in the following method:   ❏ Section 1 – Introduction   ❏ Section 2 – Description   ❏ Section 3 – Specifications   ❏ Section 4 – Installation   ❏ Section 5 – AT Interface   ❏ Section 6 – Host Software Interface   ❏ Section 7 – Interface Commands   ❏ Section 8 – Service and Support   ❏ Appendix – Glossary   Ab b re via t io n s   ABBRV DESCRIPTION   ABBRV DESCRIPTION   ATA AT attachment   bpi bits per inch   MB megabyte   Mbits/sec megabits per second   CHS cylinder - head - sector   db decibels   MB/sec megabytes per second   MHz megahertz   dBA decibels, A weighted   DMA direct memory access   ECC error correction code   fci flux changes per inch   ms millisecond   MSB most significant bit   mV millivolts   ns nanoseconds   G acceleration   PIO programmed input/output   RPM revolutions per minute   tpi tracks per inch   GB gigabyte   Hz hertz   KB kilobyte   UDMA ultra direct memory access   µsec microsecond   LBA logical block address   LSB least significant bit   mA milliamperes   V volts   W watts   1 – 1   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.   1 – 2   SECTION 2   P ro d u c t De s c rip t io n   Maxtor DiamondMax™ 2160 AT disk drives are 1-inch high, 3.5-inch diameter random access storage devices   which incorporate an on-board Ultra DMA/ ATA controller. High capacity is achieved by a balanced   combination of high areal recording density and the latest data encoding and servo techniques.   Maxtor's latest advancements in electronic packaging and integration methods have lowered the drive's power   consumption and increased its reliability. Advanced magneto-resistive read/ write heads, an state-of-the-art head/   disk assembly using an integrated motor/ spindle design allow up to four disks in a 3.5-inch package.   Exceptionally high data transfer rates and < 9.7 ms access times make these performance series disk drives   especially well-suited to high speed desktop and server applications.   Dia m o n d Ma x 2 1 6 0 Ke y Fe a t u re s   ANSI ATA-4 compliant PIO Mode 4 interface (Enhanced IDE)   Supports Ultra DMA Mode 2 for 33 MB/ sec data transfers   256 KB buffer with multi-adaptive cache manager   < 9.7 ms seek time   Zone density and I.D.-less recording   High reliability with > 500,000 hour MTBF   Outstanding shock resistance at 150 Gs   High durability with 50K constant start/ stop cycles   Advanced multi-burst on-the-fly Error Correction Code (ECC)   Extended data integrity with ECC protected data and fault tolerant servo synchronization fields   Supports EPA Energy Star Standards (Green PC Friendly) with ATA powering savings commands   Auto park and lock actuator mechanism   Low power consumption   S.M.A.R.T.

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:   MODEL   CYLINDERS   16,278   13,395   8,930   HEADS   16   15   15   15   SECTORS   CAPACITY   8,400 MB   6,480 MB   4,320 MB   3,240 MB   2,160 MB   88400D8   86480D6   84320D4   83240D3   82160D2   63   63   63   63   63   6,697   4,465   15   2 – 2   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.   On -t h e -Fly Ha rd w a re Erro r Co rre c t io n Co d e (ECC)   10 bits, single burst, guaranteed   S o ft w a re ECC Co rre c t io n   64 bits, single burst, guaranteed   28 bits, double bursts, guaranteed   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.   2 – 3   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.   2 – 4   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.   M ic r o p r o c e s s o r   The microprocessor controls the following functions for the drive electronics:   Command execution   Cache management   Data correction and error recovery   Diagnostic execution   Data sequencing   Head positioning (including error recovery)   Host interface   Index detection   Spin speed control   Se e ks   Se rvo   S.M.A.R.T.   2 – 5   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.

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.   Ca n a d ia n Em is s io n s S t a t e m e n t   This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set   out in the radio interference regulations of the Canadian department of communications.   Le present appareil numerique n'emet pas de bruit radioelectriques depassant les limites applicables aux   appareils numeriques de Class B prescrites dans le reglement sur le brouillage radioelectrique edicte par le   ministere des communications du Canada.   Ra d ia t e d Ma g n e t ic Fie ld Em is s io n s   Minimum of VDE Class B and MIL-STD-461/ 462, Method RE01 (stand-alone test configuration).   Ra d ia t e d Ele c t ro m a g n e t ic Fie ld Im m u n it y   IEC 801-3, Class 2 compliance.   Ra d ia t e d Ma g n e t ic Fie ld Im m u n it y   Per MIL-STD-461/ 462, Method RD01(15 Hz to 100 kHz, stand-alone test configuration).   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.   S a fe t y Re g u la t o ry Co m p lia n c e   All Maxtor DiamondMax™ 2160 drives comply with relevant product safety standards such as CE, CUL, TUV   and UL rules and regulations.

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:   ESD Program Element   Management   Chief coordinator   Multi-department committee   Employee training   ESD Program Function   Institute and maintain   Organize and enforce   Evaluate and improve   Educate and inform   ESD program supplies typically include: wrist- and foot-worn grounding straps; counter-top and floor antistatic   matting; wrist strap testers; ESD video and training materials.

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.   2 Connect an available power connector to J2 (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.   Striped/colored edge is pin 1   Figure 4 - 8   IDE Interface and Power Cabling Detail   IMPORTANT: After attaching the IDE interface cable and the power cable to the Maxtor hard drive, verify   that all other cables connected to other devices, the mother board or interface cards are   correctly seated.   4 – 6   INSTALLATION   At t a c h in g S ys t e m Ca b le s   Attachthe40-pinIDEinterfacecablefromtheMaxtorharddrivetotheIDEconnectorontheIDEinterfacecard.   Figure 4 - 9   System Interface Card Cabling   OR   Attach the 40-pin IDE interface cable from the Maxtor hard drive to the IDE connector on the mother board.   Figure 4 - 10   System Mother board Cabling   4 – 7   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.   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.   1 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.   4 – 8   INSTALLATION   Drive P aram te rs   MODEL   CYL   HD   16   15   15   15   15   SPT   63   63   63   63   LZone   (*)   (*)   (*)   (*)   WPcom CAPACITY   88400D8   86480D6   84320D4   83240D3   82160D2   16,278   13,395   8,930   6,697   4,465   (*)   (*)   (*)   (*)   (*)   8,400 MB   6,480 MB   4,320 MB   3,240 MB   2,160 MB   63   (*)   (*) The fields LZone (Landing Zone) and WPcom (Write Pre-comp) are not used by the Maxtor hard drive   and the values may be either 0 or the values set by the BIOS. All capacities listed in the parameters table are   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   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:   1 Turn the system OFF.   Ma s t e r Devic e   S lave Devic e   J50 J48 J46 J44 J42   J50 J48 J46 J44 J42   EIDE Interface Connector J 1   Power Connector J 2   J50 – Master/Slave   J48 – Cable Select   J46 – 4092 Cylinder Limitation   J44 – Factory Reserved   J42 – Factory Reserved   4 – 9   INSTALLATION   2 3 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.   1 2 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.

The host accesses each register   by the I/ O port address shown in this Task File register map:   I/O PORT   1F0h   1F1h   1F2h   1F3h   1F4h   1F5h   1F6h   1F7h   READ   WRITE   Data Register   Error Register   Sector Count   Sector Number   Cylinder Low   Cylinder High   Drive/Head (SDH)   Status Register   Data Register   Features Register   Sector Count   Sector Number   Cylinder Low   Cylinder High   Drive/Head (SDH)   Command Register   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:   7 0 6 5 0 4 3 0 2 1 0 ECC   IDNF   ABRT   TK0   AMNF   Interface   CRC   Data   ECC Error   Not   Used   ID   Not   Used   Aborted   Command   Track 0   Error   Address   Mark Not   Found   Not Found   Interface CRC – An interface CRC error occurred during an Ultra DMA transfer.   Data ECC Error – An non-correctable ECC error occurred during a Read Sector command.   Firm w are Problem – Indicates a firmware problem was detected, (e.g., invalid interrupt, divide overflow).   ID Not Found – Either a matching ID field not found, or a CRC error occurred.   Aborted 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   Enables or disables features through the Set Features command.   6 – 1   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.   Bit definitions follow:   7 1 6 5 1 4 3 2 1 0 LBA   DRV   HS3   HS2   HS1   HS0   Drive   Head   Select   Head   Select   Head   Select   Mode   Select   Select   Select LBA Mode – Enabling this bit for commands not supported by LBA mode will abort the selected command. When set,   the Task File register contents are defined as follows for the Read/Write and translate command:   CONTENTS   Sector Number   Cylinder Low   Cylinder High   Drive/Head   LBA BITS   0 - 7   8 - 15   16 - 23   24 - 27   Drive Select – Set to 0 to select the master drive; set to 1 to select the slave drive.   Head Select – Specifies the binary coded address of the head to be selected.   S t a t u s Re g is t e r   Contains results of the last command executed, and the drive’s status. The other seven Task File registers may   be read only when bit 7 (BUSY) of the Status register is low. Reading any of the Task File registers when   BUSY is high returns the value of the Status register. Reading the Status register also clears any interrupt   request to the host. Bit definitions follow:   7 6 5 4 3 2 0 1 0 0 BUSY   DRDY   DF   DSC   DRQ   ERR   Error   Controller   Busy   Device   Ready   Device   Fault   Device Seek Data   Complete Request   Controller Busy – Goes active when a command is written to the Command register, indicating controller task   execution. After a command, this bit resets.   Device Ready – Indicates that the drive is ready for commands. If drive ready is not present, all commands abort.   Device Fault – Indicates the drive’s detection of a write fault condition, causing all commands to abort.   Device Seek Com plete – Signifies a seek completion, and that the drive is on track.   Data Request – Indicates that the drive’s sector buffer is ready for data transfer.   Error – The Error bit sets when the previous command has completed with a non-recoverable error.   6 – 2   HOST SOFTWAREINTERFACE   Co m m a n d Re g is t e r   Contains code for the command to be performed. Additional command information should be written to the   task file before the Command register is loaded. When this register is written, the BUSY bit in the Status   register sets, and interrupt request to the host clears; invalid commands abort.

All three   cause the interface processor to initialize itself and the Task File registers of the interface. A reset also causes a   set of the Busy bit in the Status register. The Busy bit does not clear until the reset clears and the drive   completes initialization. Completion of a reset operation does not generate a host interrupt.   Task File registers are initialized as follows:   Error   1 1 1 0 0 0 Sector Count   Sector Number   Cylinder Low   Cylinder High   Drive/Head   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.   6 – 6   SECTION 7   In t e rfa c e Co m m a n d s   The following section describes the commands (and any parameters necessary to execute them),   as well as Status and Error register bits affected.   Re a d Co m m a n d s   Read Sector(s)   Read Verify Sector(s)   Read Sector Buffer   Read DMA   Multi-word DMA   Ultra DMA   Read Multiple   Set Multiple   Writ e Co m m a n d s   Write Sector(s)   Write Verify Sector(s)   Write Sector Buffer   Write DMA   Multi-word DMA   Ultra DMA   Write Multiple   S e t Fe a t u re Co m m a n d s   Set Features Mode   P o w e r Mo d e Co m m a n d s   Standby Immediate   Idle Immediate   Standby   Idle   Check Power Mode   Set Sleep Mode   Default Power-on Condition   In it ia liza t io n Co m m a n d s   Identify Drive   Initialize Drive Parameters   7 – 1   INTERFACECOMMANDS   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.   7 – 5   INTERFACECOMMANDS   S e t Fe a t u re Co m m a n d s   S e t Fe a t u re s Mo d e   Enables or disables features supported by the drive. When the drive receives this command it:   1. Sets BSY,   2. Checks the contents of the Features register,   3. Clears BSY and   4.

The actuator is parked and some circuits are powered off.   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.   Id le – 9 7 h /E3 h   Spin up and change time out value. This command will spin-up the spin motor if the drive is spun-down.   If the drive is already spinning, the spin up sequence is not executed. A non-zero value placed in the Sector   Count register will enable the Automatic Power Down sequence and their timer will begin counting down   immediately. A value of zero placed in the Sector Count register will disable the Automatic Power Down   sequence. The actuator is parked and some circuits are powered off.   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.   7 – 7   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   the host within the Time-out Interval, the drive automatically enters the STANDBY mode.

The drive will always be in the translate mode because   of Zone Density Recording, which varies the number of sectors per track depending on the zone.   Through setting the Sector Count Register and Drive Head Register, this command lets the host alter the   drive's logical configuration. As a result, the drive can operate as any equal to or less than capacity drive type.   Do not exceed the total number of sectors available on the drive:   When this command is executed, the drive reads the Sector Counter Register and the Drive Head Register   (and so determines the number of the logical sectors per track and maximum logical head number per   cylinder and will calculate the number of logical cylinders.)   Upon receipt of the command, the drive:   1. Sets BSY,   2. Saves the parameters,   3. Resets BSY and   4. Generates an interrupt.   To specify maximum heads, write 1 less than the maximum (e.g. write 4 for a 5 head drive). To specify   maximum sectors, specify the actual number of sectors (e.g. 17 for a maximum of 17 sectors/ track).   The sector count and head values are not checked for validity by this command. If they are invalid, no error   will be posted until an illegal access is made by some other command.   Moves the read/ write heads from anywhere on the disk to cylinder 0.   When this command is received, the drive:   1. Sets BSY and   2. Issues a seek to cylinder zero.   The drive waits for the seek to complete, then the drive:   1. Updates status,   2. Resets BSY and   3. Generates an interrupt.   If the drive cannot reach cylinder 0, the Error bit is set in the Status register, and the Track 0 bit is set in the   Error register.   NOTE: If a maximum head and sector number is selected – such that the number of cylinders will exceed 65,535 – then   the maximum cylinder value will be reduced to 65, 535.   7 – 12   INTERFACECOMMANDS   S e e k , Fo rm a t a n d Dia g n o s t ic Co m m a n d s   S e e k   Initiates a seek to the track, and selects the head specified in the Command block.   1.

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.

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.   7 – 13   INTERFACECOMMANDS   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.   D3h   D4h   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.   DBh   Enable/Disable Automatic Off-Line   To enable this feature, set the Sector Count register to F1h or 0 to disable.   7 – 14   SECTION 8   S e rvic e a n d S u p p o rt   S e rvic e P o lic y   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.

Customer returns the original drive and credit card draft is destroyed.   S u p p o rt   Te c h n ic a l As s is t a n c e   Highly-trained technicians are available 6 a.m. to 6 p.m. (Mountain Standard Time) Monday through Friday   to provide detailed technical support.   U.S. and Canada   Language support: English, Spanish   800-2MAXTOR, press 1 (800-262-9867)   303-678-2260   Voice   E-mail   Fax   Outside U.S. and Canada   303-678-2015   Europe   Voice   E-mail   Fax   Language support: English, French, German   + 353 1 204 11 11   + 353 1 286 14 19   Asia/ Pacific   Voice   Contact your local Maxtor Sales Office for assistance   Language support: English   E-mail   Ma xIn fo S e rvic e   Use a touch-tone phone to listen to technical information about Maxtor products and the top Q&A’s   from our 24-hour automated voice system.   U.S. and Canada   800-2MAXTOR (800-262-9867)   Press 1, wait for announcement, press 1.   303-678-2015, press 1   Outside U.S. and Canada   8 – 1   SERVICEANDSUPPORT   Ma xFa x™ S e rvic e   Use a touch-tone phone to order Technical Reference Sheets, Drive Specifications, Installation Sheets and   other documents from our 24-hour automated fax retrieval system.
