 Jumper Setting
 ==============

 GoDrive 40/80AT hard disk drives can be configured as a master or a
 slave drive, using either the jumper blocks on the drive's controller
 board or by grounding certain lines on the interface connector.

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


 There are two sets of jumper pins. The SP is labeld "SP" for slave
 present. The other set (three jumper pins) has two labels "CS" and
 "DS" for Cable Select and Drive Select. The center pin is common to
 both the CS and the DS positions.

 When a jumper block is on the center pin and the pin nearest the
 interface connector, DS is enabled. When a jumper block is on the
 center pin and the pin furthest from the interface connector, CS is
 enabled.


 NOTE
 Jumper blocks can be placed in a storage position by locating them on
 one jumper pin as shown in the following Figure.

 Master Drive Configuration
 --------------------------
 GoDrive 40/80 AT hard disk drives are configured at the factory as a
 master drive as defined by the CAM (Common Access Method). This
 configuration is shown in the following figure.

 Master Drive with Slave Present
 -------------------------------
 When GoDrive 40/80 AT hard disk drives are configured as a master
 drive, the drive looks for a slave drive by monitoring the PDIAG/DASP
 lines.

 Some hard disk drives when configured as a slave do not indicate
 their presense on these two lines (GoDrive does). To indicate that a
 slave is present for these drive (when using GoDrive as a master),
 the slave present (SP) pins on GoDrive master must be jumpered as
 shown.

          +----+Jumper            +----+Jumper


 Cable Selection
 ---------------
 The drive can be configured such that its status as a master or slave
 drive can be determined by the cabling from the host system.

       ++++++Pins           +++++++++ Pins

          +----+Jumper         +----+Jumper

 NOTE
 This is extremely helpful when GoDrive 40/80 AT is used as a
 removable subsystem where it can be either master drive or a slave
 drive depending upon the cable to which is connected.

 When the GoDrive is configured for cable selection, as shown in the
 Figure below, it is the master drive if Pin 28 is grounded and a
 slave if Pin 28 is not grounded.

 For systems that do not use Pin 28 for another purpose (e.g., Address
 Latch Enabled), the host system can tie Pin 28 to ground. Then the
 cable connecting the host to the master has Pin 28 enabled (i.e., a
 circuit exists), while the cable connecting the slave to either the
 host or the master has the Pin 28 line servered.

 Systems that use Pin 28 can use the cable selection method by
 performing the following:

   1. Connect the system cable in the following order
      host <--> slave <--> master.

   2. Cut the Pin 28 line between the slave and the master. This
      allow Pin 28 to operate normally (an open - served connection)
      between the host and the slave.

   3. Tie Pin 28 (within the master drive header) to a nearby ground
      (Pin 30, for example).

 This process will allow the master drive to have Pin 28 grounded
 while allowing the Pin 28 to be open between the host and slave
 drive.

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

 Dimensions and Mounting
 -----------------------
 The drive can be mounted in any orientation. Maximum screw length is
 3mm with three minimum full threads. The maximum mounting torque for
 these screws is 120 inch-ounces.

 NOTE
 If the bottom mounting holes are used, the mating surface of the
 assembly that attaches to the bottom must have a flatness of 0.076mm
 (0.003 inches) or better.


 Ventilation
 -----------
 GoDrive 40/80AT hard disk drives can operate without a cooling
 fan, provided the ambient air temperature des not exceed 55*C
 (131*F). Any user-designed cabinet must provide adequate air
 circulation to prevent the maximum temperature from being exceeded.


 Cable Connector
 ---------------
 GoDrive 40/80AT hard disk drives have a single 2 x 22 connector (on
 2mm centers) for both power and data. The connector also includes
 four pins which are reserved for factory test points.

 The recommended system mating connector is a Dupont part number
 69764-044 or equivalent. The maximum cable length is 18 inches. To
 assure that the system cable connector is installed with the proper
 orientation, plug the Pin 20 hole on the system connector.

 Power Sequencing
 ----------------
 GoDrive 40/80AT hard disk drives require no power sequencing.
 Applying or removing power during drive operation does not cause data
 to be lost or corrupted. Although the drive requires no power
 sequencing, Quantum recommends that is a controlled power dwon is
 available from the system (e.g., in a system with an auto resume
 feature), a Standby command should be issued to the drive prior to
 the removal of power.

 CAUTION
 Data may be lost or corrupted in a sector being written at the time
 of a power loss.

 During power-on or power-off, the drive can sustain an open or a
 short circuit on either the voltage or the return line.


 Electrical Interface
 --------------------
 All signals are TTL-compatible. A logic one is greater than 2.0 volts
 and less than 5.25 volts. Logic zero is greater than 0.0 volts and
 less than 0.7 volts. The drive requires no terminating resistors.

 General Description
 -------------------
 Quantum's GoDrive 40AT and GoDrive 80AT hard disk drives are part of
 a family of high performance, 2.5-inch form factor hard disk drives
 manufactured to meet the highest product-quality standards.

 GoDrive 40/80AT hard disk drives feature an embedded AT drive
 controller and uses AT commands to optimize system performance. Be-
 cause the drive manages media defects and error recovery internally,
 these operations are fully transparent to the user.

 Note: The GoDrive 40/80AT does not include a faceplate!


 Features
 --------

 - Low-profile, optimized for number of disks

 - Data-transfer rate of up to 4.0 megabyte per second, using
   programmed I/O

 - Proprietary 32K, look-ahead, programmable DisCache with WriteCache
   (8K on the GoDrive 40AT)

 - 112-bit Reed Solomon Error Correction Code (ECC), with 48-bit
   double burst correction

 - Automatic retry on read errors

 - Transparent media-defect mapping

 - High performance, in-line defective sector skipping

 - Reassignment of defective sectors discovered in the field, without
   reformatting

 - Automatic actuator shipping lock and dedicated landing zone

 - Emulation of IBM PC/AT task file register and all AT fixed-disk
   commands

 - Ability to daisy-chain two drives on the interface

 Error Reporting
 ---------------
 At the start of a command's execution, GoDrive 40/80AT hard disk
 drives check the COMMAND register for any conditions that would lead
 to an abort command error. The drive then attempts execution of the
 command. Any new error causes execution of the command to terminate
 at the point at which it occurred. The following table list the valid
 errors for each command.

 TK0NF = Track zero not found error
 UNC   = Uncorrectable data error

 The format for GoDrive 40/80AT allocates one sector per cylinder
 as a spare. In the factory, the media is scanned for defects. If a
 sector on a cylinder found to be defective, the sector's address is
 added to the drive's defect list. Sectors physically subsequent to
 the defective sector are assigned logical block addresses such that
 a sequential ordering of logical blocks results. This in-line sparing
 technique is employed in an attempt to eliminate throughput reduction
 resulting from a single defective sector on a cylinder.
