 The drive will operate in all axis (6 directions).


 Recommended Mounting Configuration
 ----------------------------------
 Maxtor 7000 Series drive design allows greater shock tolerance than
 that afforded by larger, heavier drives. The drive may be mounted in
 any attitude using four size 6-32 screws with 1/8" maximum
 penetration and a maximum torque of 5-inch pounds.

 Allow adequate ventilation to the drive to ensure reliable drive
 operation.


 Air Filtration System
 ---------------------
 All 7000 Series drives are designed to operate in a typical
 office environment with minimal environmental control. Over the life
 of the drive, a 0.3 micron filter and breather filter (located within
 the HDA) maintain a clean environment to the heads and disks.


 Read/Write Electronics
 ----------------------
 An integrated circuit mounted within the sealed enclosure (near the
 read/write heads) provides one of four head selection (depending on
 the model), read preamplification, and write drive circuitry.


 Read/Write Heads and Disks
 --------------------------
 Low mass, low force read/write heads record data on two 3.5"
 diameter disks. Maxtor uses a sputtered thin film medium on all
 disks for 7000 Series drives.


 Drive Mechanism
 ---------------
 A brushless DC direct-drive motor rotates the spindle at 4,480 RPM
 (  0.1%). The dynamically balanced motor/spindle assembly ensures
 minimal mechanical runout 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.


 Voice Coil Actuator
 -------------------
 All 7000 Series drives employ a rotary voice coil actuator which
 consists of a moving coil, an E-block or actuator arm assembly, and
 stationary magnets. The actuator moves on a low-mass, low-friction
 center shaft. The low friction generated contributes to fast average
 access time and low power consumption.


 Automatic Headpark and Lock Operation
 -------------------------------------
 Immediately following power-down, dynamic braking of the spinning
 disks delays momentarily and lets the heads move to an inner
 mechanical stop. A small fixed magnet holds the heads in place as the
 disk spin down. The heads are released only when power is again
 applied.


 Dual Drive Support
 ------------------
 Two drives may be accessed via a common interface cable, using the
 same range of I/O addresses. The drives are jumpered as drive 0 or 1,
 and are selected by the drive select bit in the Drive/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: drive 0 is
 the master, and drive 1, the slave. When J20 is closed (factory
 default), the drive assumes the role of master; when open, the drive
 acts as a slave. In single drive configurations, J20 must be closed.

 Cable Select
 ------------
 CSEL (cable select) is an optional feature per ATA CAM 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.

 NOTE
 If the Cable Select jumper (J24) is installed, the Master/Slave
 jumper (J20) will be ignored.


 Sector Address Translation
 --------------------------
 All 7000 Series drives feature a Universal Translate Mode. In an
 AT-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).

 These drives powers-up in the Translate Mode:

 Model     |Cylinders |Heads |Sectors
 ----------+----------+------+-------
 71050A    |  2045    | 16   | 63
 ----------+----------+------+-------
 71626A/AP |  3158    | 16   | 63
 ----------+----------+------+-------
 71260A/AP |  2448    | 16   | 63
 ----------+----------+------+-------
 71084A/AP |  2105    | 16   | 63
 ----------+----------+------+-------
 7541A/AP  |  1052    | 16   | 63


 Interface Connector
 -------------------
 All 7000 Series AT drives have a 40-pin interface connector mounted
 on the PCBA. The drive may connect directly to the host; or it can
 also accommodate a cable connection (maximum cable length: 18
 inches).

 (Striped Edge = Pin 1)


 Buffer Segmentation
 -------------------
 The data buffer is organized into three segments: the read buffer,
 the write buffer, and an micro controller scratch pad. The read
 segment occupies half of the buffer and operates as a circular read-
 ahead buffer. The write segment occupies the other half. During write
 operations, it contains the host write data. Commands ATA Read Buffer
 (E4) and ATA Write Buffer (E8) are implemented per CAM specification
 4a.


 Read-Ahead Mode
 ---------------
 Normally, this mode is active. Following a read request, disk read-
 ahead begins on the first sector and continues sequentially until the
 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.

 Introduction
 ------------
 Maxtor 7000 Series AT disk drives are 1" high, 3.5" random access
 storage devices which incorporate an on-board AT controller. Maxtor
 engineers have applied recent advances in hard drive technology to
 the design and manufacture of these drives. High data transfer rates
 and fast access times make them especially well-suited to desktop and
 workstation applications.


 Defect Management Zone (DMZ)
 ----------------------------
 Each drive model has a fixed number of spare sectors per DMZ:
 71626A/AP = 6,
 71260A/AP = 5,
 71084A/AP = 4 and
 7541A/AP = 2
 all of which are located at the end of each DMZ. Upon detection of a
 bad sector that has been reassigned, the next sequential sector is
 used.

 The first spare sector makes up for the loss of sector 3, and so
 maintains the sequential order of data, with 3 spare sectors still
 allocated for that cylinder. This push down method assures maximum
 performance.

 In the rare occurrence that the number of reassigned bad sectors
 exceed the number of spare sectors allocated for that cylinder, an
 alternate track area in Zone 6 of the disk is used. All models
 have five (5) alternate tracks per surface.


 Error Correction Code
 ---------------------
 On-the-fly Hardware ECC
 -----------------------
 41 bits, single burst, guaranteed
 17 bits, double burst, guaranteed

 Software ECC Correction
 -----------------------
 113 bits, single burst, guaranteed
 17 bits, five burst, guaranteed


 Zone Density Recording
 ----------------------
 The disk capacity is increased with bit density management - common
 with Zone Density Recording. Each disk surface is divided into 10
 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.


 Execute Drive Diagnostics
 -------------------------
 Commands the drive to implements the internal diagnostics 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.

 This table presents the codes and their descriptions:

 Note that the value in the Error register should be viewed as a
 unique 8 bit Code.

  +-----------+----------------------------------+
  |Error Code | Description                      |
  +-----------+----------------------------------+
  |    01     | no error detected                |
  +-----------+----------------------------------+
  |    02     | formatter device error           |
  +-----------+----------------------------------+
  |    03     | sector buffer error              |
  +-----------+----------------------------------+
  |    04     | ECC circuitry error              |
  +-----------+----------------------------------+
  |    05     | controller microprocessor error  |
  +-----------+----------------------------------+
  |    8x     | slave drive failed (Note)        |
  +-----------+----------------------------------+
                Note: If a slave drive fails diagnostics, the master
                drive OR's 80 hex with its own status, and loads that
                code into the Error register.

                If a slave drive passes diagnostics (or a slave is
                absent), the master drive OR's 00 with its own status
                and loads that code into the Error register.


 EISA Type "B" and Type "F" DMA Modes
 ------------------------------------
 Direct Memory Access (DMA) transfers improves system performance by
 significantly improving troughtput.


 Physical Configuration Sectors per track
 ----------------------------------------
 Zone 1 = 156    Zone 2 = 154    Zone 3 = 150
 Zone 4 = 140    Zone 5 = 132    Zone 6 = 126
 Zone 7 = 120    Zone 8 = 108    Zone 9 = 100
 Zone 10 = 90


 Data transfer rate (MBytes per second)
 --------------------------------------
 To from media

 Zone 01 = 8.10    Zone 06 = 6.50
 Zone 02 = 8.02    Zone 07 = 5.94
 Zone 03 = 7.68    Zone 08 = 5.55
 Zone 04 = 7.18    Zone 09 = 5.08
 Zone 05 = 6.80    Zone 10 = 4.61


 Logical Block Addressing
 ------------------------
 The Logical Block Address (LBA) mode can only be utilized into
 systems that support this form of translation. The cylinder, head and
 sector geometry of the drive, as presented to the host, differs from
 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)+HHDAxHSPT+HNHDxHSPTxHCYA  (1)
        = (HSCA-1)+HSPTx(HHDA+HNHDxHCYA)     (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 the data stored
 on the disk and other drive related operations.


 Installation Steps
 ------------------
 Warning!
 Pre-loaded Software on Drive
 This Maxtor hard drive is factory configured with a 112MB partition
 containing Max Blast Disk Manager installation software by Ontrack
 Systems. Please leave this partition intact until you choose the
 appropriate installation option.

 As a precautionary measure, Maxtor recommendeds that you download a
 copy of the MaxBlast software to a blank diskette even if you choose
 an alternate high-level formatting method.

 Install a 40-pin ribbon connector. The striped edge of this cable
 represents pin 1 and must be oriented towards pin 1 at the drive
 connector and at the host connector.

 Install a DC power connector...

 If AT BIOS supports user programmable parameters, program System BIOS
 with one of these default Parameters.

 Model      Cylinders   Heads    Sectors   Capacity
 71262AP    3158        16       63        1,626 MB
 71260AP    2632        16       63        1,260 MB
 71084AP    2105        16       63        1,084 MB
  7813AP    1579        16       63          813 MB
  7541AP    1052        16       63          541 MB

 If AT
 BIOS does not support programmable drive type, choose parameters that
 closely match, but do not exceed, the drive's formatted capacity.

 The drive is now ready for partitioning and high-level formatting
 with any operating system. For example:

          Partition the drive using the FDISK command from MS-DOS
          version 3.3 of higher.
          High level format the drive using the FORMAT command from
          MS-DOS version 3.3 or higher.

 Secure the drive in a suitable drive bay with 6-32 x 1/4" screws.

 NOTE
 WPC and Landing Zone BIOS entries do not need a specific number for
 proper operation. Maxtor AT interface hard drives will ignore and
 override any numbers programmed.
