 J6  Master/Slave
 ----------------
     Pins 1-2   OPEN    Only drive in single system
                        Master in dual drive system
                CLOSED  Slave in dual drive system

 The Master/Slave Jumper is used to configure the drive as a Master
 or Slave. If the jumper is removed, the drive is a Master. If the
 jumper is installed, the drive is a Slave. For single drive systems,
 the jumper should be removed.


 J6  Drive Active
 ----------------
     Pins 3-4   OPTIONAL One drive in single drive system
                OPTIONAL Master in dual drive system
                OPTIONAL Slave in dual drive system


 The Drive Active jumper is used to provide a current DASP (pin 39) of
 the interface to indicate drive activity. If the jumper is installed,
 current will be supplied when the drive is active. If the jumper is
 removed, no current is supplied (the DASP line is a "wired OR".


 J6  Slave Present
 -----------------
     Pins 5-6   OPEN     One drive in single drive system
                         Master in dual drive system
                OPTIONAL Slave in dual drive system


 The Slave Present jumper is used by the slave to indicate its
 presense. It should be installed on the slave drive only. This
 jumper is not necessary if both drives are Maxtor LXT drives.


 J6  Two Drive System
 --------------------
     Pins 7-8   OPEN     One drive in single drive system
                CLOSED   Master in dual drive system
                OPEN     Slave in dual drive system


 The Two Drive System jumper is used by the master drive to indicate
 the presense of a slave drive. This jumper is not installed by the
 slave drive or if only one drive is used.


 J6  Sync Spindle Pulse Source
 -----------------------------
     Pins 9-10  OPEN     If receiving the pulse
                CLOSED   If transmitting the pulse

 This jumper may be installed in only one drive in an array.

 The Sync Spindle jumper is used to indicate which drive will supply
 the sync index pulses. Only one master in the disk drive array should
 have this jumper installed. This jumper should be removed in all
 other cases.


 The drive is shipped configured for use in a single drive system.


 J4  Service Connector
 ---------------------
 Connector J4 is a ten-pin service connector provided for serial
 input, synchronous spindle, and the LED source current. Its mating
 connector is a Berg 6976410 part or Dupont part number 69764-010.

      7  | N/C
      8  | SPDL Pulse Ref
      9  | +5V
     10  | -LED DRV

 When an LED is connected to pins nine and ten, it functions in the
 same manner as the LED which is mounted on the disk drive's face-
 plate. This is typically used in cases when the drive is mounted in
 a position where the LED is not visible or the faceplate is removed.

 Pins two through four are the RS-422 lines used to down load firm-
 ware updates to the microprocessor which are then stored on the disk.
 Pins three (transmit data) and four (receive data) are the main
 communication lines. Pin two is used to debug the processor and for a
 non-maskable interrupt. Pins five and six are signal ground lines.
 Pin eigth is used to transceive sync pulses for multi-drive spindle
 synchronization.

 When using the service connector for a synchronized spindle
 configuration, J4 pins 6 and 8 of each drive should be connected by a
 twisted pair of wire. One end of this "daisy chain" should have a 2K
 ohm resistor between J4 pins 8 and 9, while the other end will supply
 the pulse source.

   |                 |
   +-----------------+

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


 Mounting
 --------
 The drive may be mounted in any position. Certain switching power
 supplies may emanate electrical noise, which can degrade the
 specified read error rate. For best results, orient the drive so that
 the PCB assembly is not adjacent to these noise sources.

 Twelve mounting holes, four on the bottom and four on each side, are
 provided for mounting the drive into an enclosure. The size and
 location of these holes, are identical to industry standards.

 Caution: Mounting screw lengths must be chosen so that no more than
 0.125 inch of the screw is available to enter the frame mounting
 hole. The screw length, if incorrect, will damage the PCB during
 installation and void the warranty. The torque applied to the
 mounting screws should be between 9 and 12 inch-pounds.

 The faceplate is clipped to the front of the HDA and may be removed
 in installations that do not require it. Lift up on the faceplate
 clips and unplug the LED cable from the PCB.


 Air Flow Requirements
 ---------------------
 It is recommended that air flow over the drive PCBA be a minimum of
 25 cubic feet per minute.

 The maximum temperature of the HDA cover (measured at a point
 centered on the cover beneath the PCB), should not be greater than
 11* C above the ambient temperature (measured 1/8 inch away from the
 PCB). For some installations 200 LFM of air flow may be required to
 maintain the temperature specified.


 Installation Requirements
 -------------------------
 The LXT ATA drives must operate in a temperature range between 41*F
 and 122*F (5*C and 50*C). The drive should be installed in
 applications where temperature extremes outside of this range are
 avoided.

 Caution: These requirements must be met to ensure proper functioning
 of the drive. If they are not met, data loss and/or permanent damage
 to the drive may result.

 The faceplate is screwed to the front of the HDA in some LXT models,
 and clipped to the front in others. The faceplate may be removed in
 installations that do not require it.


 Shipping
 --------
 At power down, the heads are automatically positioned over the
 dedicated landing zone (nondata) on each disk surface. The automatic
 shipping look solenoid is also engaged at this time. Maxtor ships the
 drive in single and multipack shipping containers. Users can ship the
 drive installed when the nonoperating shock and vibration limits are
 not exceeded.


 Interface
 ---------
 This chapter describes the interface requirements of the LXT ATA
 drives, which are compatible with the AT-BUS. Data is transferred in
 a 16-bit wide parallel data path from the host to the drive. Data
 transfer is controlled by commands sent from the host. The drive
 performs all operations necessary to write data to or read data from
 the medium. Data read from the medium is placed in a buffer prior to
 being transferred to the host.

 This allows two drives to be connected to the host. The primary drive
 is designated as the master drive and the secondary drive is
 designated as the slave drive.

 The maximum cable length connecting the host and the drives is
 twenty four inches (0.61 meters).


 Interface Connector
 -------------------
 The interface connector is a 40-pin dual-row header connector. A key
 for the mating cable connector is provided by the removal of pin 20.
 The corresponding hole on the cable connector should be plugged. The
 cable connector should be keyed to prevent the possibility of
 installing it upside down.

 Recommended part numbers for the mating connector and cables are
 shown below. Equivalent parts may be used.

 Connector         3M-3417-7000 (Strain Relief 3448-2040, AMP P/N
                   1-499506-0)
 Cable             Flat Cable (Stranded AWG 28) 3M-3365-40
 Shielded Cable    Flat Cable (Stranded AWG 28) 3M-3517-40



 J3  Power Connector
 -------------------
 The four-pin DC power connector J3 is similar to AMP's MATE-N-LOOK
 connector, part number 350543-4, however, is surface mounted to the
 PCB rather than freehanginng as the AMP part is. Part numbers for the
 recommended mating connector and contacts are shown below.

 Connector         AMP 1-480424-0
 Contacts          AMP 61173-4 (Loose Piece), AMP 350078-4 (Strip)


 Buffer Access
 -------------
 The LXT products use zone density recording. This recording technique
 varies the number of bytes per track (Mbytes/sec) which must be read
 or written.

 The LXT ATA drives are manufactured with either 32K or 64K of buffer
 RAM. To confirm the buffer size of your drive, execute the IDENTIFY
 command.


 Translate Mode
 --------------
 The drive always operates in the translate mode because it uses
 zoned recording techniques. The drive firmware translates logical
 sector requests from the host into corresponding physical sector
 requests.

 Because the host communicates with the drive using physical drive
 parameters, a mapping address translation is needed to fully utilize
 the capacity of the drive. This also makes selecting a drive type
 from the BIOS tables easier. The drive type selected should have a
 capacity equal to or less than the formatted capacity of the drive.


 Note: To achieve full memory capability of the LXT-535A drive, an
 advanced BIOS must be used. The standard BIOS allows for only 1,024
 cylinders (1,024 x 16 x 63 x 512 = 528 MB).


 Air Filtration System
 ---------------------
 The disks and read/write heads are assembled in a Class 100
 environment and then sealed within the head disk assembly (HDA).
 The HDA contains an absolute filter, mounted inside the casting, to
 provide constant internal air filtration.


 J4 Service Connector LXT-200A
 -----------------------------
 Connector J4 is a service connector providing the RS-232 interface
 and the ability to carry the LED signal beyond the drive. The RS-232
 is used to load new firmware updates to the drive. The service
 connector is a ten-pin part. The mating connector is a Berg 6976410
 part.

 When an LED is connected to pin nine (+) and pin ten (-), that LED
 functions in the same manner as the LED which is mounted on the
 drive's faceplate. This is typically used in cases where the drive is
 mounted in a position where the drive's LED is not visible and the
 faceplate is removed.

 Pins two through four are the RS-232 lines used to down load firmware
 updates to the microprocessor which are then stored on the disk.
 Pins three (transmit data) and four (receive data) are the main
 communication lines. Pin two is used to debug the processor and for
 a non-maskable interrupt. Pins five and six are signal ground lines.


 Ground Connector
 ----------------
 Logic ground and chassis ground are tied together and an insert
 description lug is provided for connection to system ground.

 Defect Management
 -----------------
 A complicated flaw scan process to generate the defect list is done
 at the factory for every drive. As shipped from the factory, the
 drive is pre-formatted with all defects reassigned to spare sectors.
 When reassigning defect sectors, the track is laid out again so that
 the defect area is skipped. One-to-one interleave and skewing factors
 are rearranged to maintain the streaming performance. The drive is
 assumed to be error-free after formatting.


 Synchronized Spindle
 --------------------
 The LXT ATA drives are able to synchronize their spindles together
 for use in disk drive arrays.

 This is accomplished by having all drives in the array synchronized
 to a common pulsed signal. This sync signal can be provided by either
 an external source or one of the drives. The sync signal can be
 transceived on either the service connector (J4 pin 8) or the ATA bus
 (J1 pin 28). However, at the time this manual was printed,
 synchronized spindle was not available on J1 pin 28.

 If the sync pulses are to be generated by an external source, the
 sync pulses should be a negative going TTL pulse with a minimum width
 of 2  sec and a frequency of 60 Hz +/- 0.5%.


 Power-Up Sequence
 -----------------
 DC power (+5V and +12V) may be supplied in any order. Both power
 supplies must be present and within the tolerances of the power
 sensing circuit, before the spin motor will spin up. When the spindle
 reaches full speed, the actuator lock automatically disengages. The
 drive spins up and becomes ready within 8 seconds. The drive
 executes its recalibration sequence whenever power is applied.

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.
