   +-----------------+

 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.

MAXTOR    IDE INSTALLATION

            INSTALLATION PROCEDURE FOR AN IDE DRIVE
            ---------------------------------------
 1. Install a 40 pin Data Cable ensuring that pin 1, which can be
    identified by the striped edge of the cable, is closest to the
    power connector on the drive.

 2. Install a DC power cable to the back of the drive.

 3. Verify the jumper configurations for Master/Slave operation
    (Note:  Master will be the bootable drive. The slave will not
    be bootable.) Also make sure the existing C: drive is jumped
    to be the Master in a two drive system, not the only drive in
    the system.

 4. Apply power to the computer.

 4a. When memory test is complete go into your system's Standard
     CMOS set-up.
     (Note: There are various ways to get into CMOS set-up, please
     refer to system's manual for instructions.)

 4b. If your system's BIOS supports a user programmable drive
     type, program the BIOS with the default parameters of your
     drive. If your system does not support a user programmable
     drive type choose parameters that closely match but do not
     exceed the drives MegaByte capacity. Escape from set-up
     then choose write to CMOS and exit.

 5. Boot from a DOS diskette that has FDISK.EXE and FORMAT.COM on
    it. At the A> prompt type in FDISK. At the menu options select
    option 1 to create a DOS partition. Another menu will appear
    and from those options choose 1 to create a Primary DOS
    partition. Select yes to make 1 large partition and it will
    automatically become active. Then escape from FDISK.

 6. At the A> prompt type in FORMAT C:/S This does a high-level
    format on the drive and transfers the system files in order for
    the drive to be bootable. (Note: IDE drives are low-level
    formatted from the manufacturer and only need a high-level
    format).

    To configure the drive as a slave drive repeat steps 1-4 and
    proceed with steps 5a. and 6a. as follows:

  5a. At the C> prompt type in FDISK. When the menu options appear
      select option 5 to switch to the second drive. Enter fixed
      disk drive number 2. Then choose option 1 to create a DOS
      partition, then select option 1 again to create a Primary DOS
      partition or option 2 to create an Extended DOS partition.
      (Note: C and D drives will always be the Primary partitions
      but only the Primary partition on C: will have a status of
      active).

  6a. Proceed with a high-level format on the drive by typing FORMAT
      D: (Note: Make sure the correct drive letter has been selected
      for format).

 7. The drive is now bootable. As a test remove the DOS diskette
    from A and press reset to reboot the computer,  a  C> should be
    displayed, the drive is now ready for operation.
