* Reserved for factory use

numerous options controlled by SCSI commands affect the operation of
the drive.) Two of these jumpers, PF, and SS, are reserved for
factory use. However, you might need to change some of the other
jumpers to configure the drive properly. These user-configurable
jumpers include:

   * TE            - Termination Enable Jumper

   * EP            - Enable Parity Jumper

   * WS            - Wait/Spin Jumper

   * A2,A1,A0      - SCSI-Bus Identification Jumpers

   * DS            - Delay Spin

When you change any jumper settin the new setting is in effect the
next time the drive is powered on.

TE Termination Enable Jumper
----------------------------
One of the requirements of the SCSI bus is that it be properly
terminated. If more than one SCSI device is connected to the host,
only the last one must be terminated. The TE (Termination Enable)
jumper, when installed, enables an active termination circuit,
thereby terminating the SCSI bus. With the TE jumper off, bus
termination is disabled.

NOTE
There are no Terminator Resistor packs to remove on Grand Prix
products.

EP Enable Parity Jumper
------------------------
The Enable Parity (EP) jumper controls parity checking of data across
the SCSI bus. With parity checking enabled, the drive performs parity
checking. With parity checking disabled, the drive continues to
generate parity information, but not perform parity checking.

At the factory Quantum configures the Grand Prix XP34301/32151 hard
disk drive with parity enabled; that is, with a jumper installed
across the pins labeled EP. To disable parity checking, remove the
jumper from the EP pins.

WS Wait/Spin Jumper
--------------------
With the Wait/Spin (WS) jumper disabled, at a power on or reset, the
drive motor starts to spin automatically, and the drive prepares
itself to perform read or write operations without the need for a
start command. At a power or reset, with the Wait/Spin jumper
enabled, the host must send a START/STOP UNIT command to activate the
drive motor for read or write operations. In addition, with the W/S
jumper enabled, the drive performs power sequencing to prevent an
overload of the host's power supply due to simultaneous, peak start-
up current demands from multiple devices.

At the factory, Quantum configures the Grand Prix XP34301/32151 hard
disk drive with the Wait/spin jumper disabled; that is, without a
jumper installed across the pins labeled WS. To enable the Wait/spin
jumper, install a jumper across the WS pins.

A2/A1/A0 50-Pin SCSI-Bus Device Identification
-----------------------------------------------
Used in combination, the jumper settings across A2, A1, and A0 de-
termine the Grand Prix XP34301/32151 hard disk drive's SCSI-bus
device identification (SCSI ID). By default, Quantum configures the
drive with a SCSI ID of six; that is, with jumpers installed across
the pins labeled A2 and A1, and no jumper installed across the pins
labeled A0.

 The SCSI bus supports up to eigth devices, including the host system.
 A device's identification number determines its priority and must be
 unique in the system.

Delay Spin Jumper
-----------------
With the Delay Spin (DS) jumper disabled, the drive will start power
up sequence immediately when power is applied. With the DS jumper
enabled, the drive will pause 8 seconds times device I.D.

J13 Alternate Address Connector
-------------------------------
The drive's Alternate Address Connector (J13) is mounted on the back
edge of the PCBA.

When external SCSI ID addressing is used, all jumpers installed
across the pins labeled A2, A1, and A0 at J9 must be removed.

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

Orientation
-----------
The mounting holes on the Grand Prix XP34301/32151S hard disk drive
allow the drive to be mounted in any orientation.

Screws
------
#6-32 UNC screws are recommended. To avoid stripping the mounting-
hole threads, the maximum torque applied to the screws must not
exceed 8 inch-pounds.

Clearance
---------
The printed-circuit board assembly (PCBA) is very close to the
mounting holes. Clearance from the drive to any other surface -
except mounting surfaces - must be 2.6 millimeters (0.10 inches)
minimum. The specified screw length allows full use of the mounting-
hole threads, while avoiding damaging or placing unwanted stress on
the PCBA.

 J3 DC Power Connector

J1 SCSI Connector 50-PIN
-------------------------
The SCSI cable connector (J1) on the Grand Prix XP34301/32151S hard
disk drive is a 50-pin universal header. A key slot on the header
prevents the incorrect installation of the header connector on the
SCSI cable. To prevent the header connector on the SCSI cable from
being plugged in backwards, use only a keyed header connector.

Power
-----
The Grand Prix XP34301/32151S hard disk drive operates from two
supply voltages:

   * +12V   5%
   * + 5V   5%

 The allowable ripple and noise for each voltage is 200 mV peak-to-
 peak for the +12 Vdc supply (60 Hz - 100 MHz) and 100 mV peak-to-peak
 for the +5 Vdc supply (60 Hz - 100 MHz).

 Power Sequencing
 ----------------
 You can apply the power in any order or manner, or short or open
 either the power or power-return line with no loss of data or damage
 to the disk drive. However, data might be lost in the sector being
 written at the time of power loss. The drive can withstand transient
 voltages of +10% to -100% from nominal while powering up or down.

Air Filtration
--------------
Grand Prix hard disk drives are Winchster-type drives. The heads fly
very close to the media surface, at a nominal flying height of 0.3
microinches. Therefore, it is essential that the air circulating
within the drive be kept free of paticles. Quantum assembles the
drive in a Class-100, purified-air environment, sealing the drive
mechanism under a metal cover. When the drive is in use, the rotation
of the disks forces the air inside the drive through an internal
filter.

Disk Caching
------------
The Grand Prix XP34301/32151S hard disk drive incorporates DisCache,
a 512K disk cache, to enhance drive performance. 256KB are allocated
to the Read Cache and 128 KB are allocated to the Read Cache and 128
KB are allocated to the write cache. This integrated feature can
significantly improve system throughput. Read and write caching can
be enabled or disabled using the MODE SELECT command.

  | Operating Mode  | Measured Noise |
  +-----------------+----------------+
  | Idle On Track   | < 4.5 bels     |
  +-----------------+----------------+
  | Seeking  Random |   4.8 bels     |
  +-----------------+----------------+

Automatic Actuator Lock
-----------------------
To ensure data integrity and prevent damage during shipment, the
Grand Prix XP34301/32151S uses a dedicated landing zone and Quantum's
patented AIRLOCK. The AIRLOCK holds the headstack in the landing zone
whenever the disks are not rotating. It consists of an air vane
mounted near the perimeter of the disk stack and a locking arm that
restrains the actuator arm assembly.

When power is applied to the motor and the disk stack rotates, the
rotation generates an airflow on the surface of the disk. As the flow
of air across the air vane increases with disk rotation, the locking
arm pivots away from the actuator arm, enabling the headstack to move
out of the landing. When DC power is removed from the motor, an
electric return mechanism automatically pulls the actuator into the
landing zone, where the AIRLOCK holds it in place.

Ventilation
-----------
The rack, cabinet, or drawer environment for the Grand Prix XP34301/
32151S hard disk drive must provide cooling of the electronics and
head and disk assembly (HDA). It is recommended that the drive be
oriented or air flow be directed so that the least amount of airflow
resistance is created while providing air flow to the electronics
and HDA.

Product Overview
----------------
Quantum's Grand Prix XP34301/32151 hard disk drives are part of a
family of high-performance, 1.6-inch-high, hard disk drives
manufactured to meet the highest product quality standards. Grand
Prix hard disk drives use nonremovable, 3 -inch hard disks.

Grand Prix hard disk drives feature an embedded SCSI drive controller
and use SCSI commands. The drive manages media defects and error
recovery internally, so these operations are transparent to the user.

Formatted Capacity
------------------
At the factory, the Grand Prix XP34301/32151 receives a low-level
format that creates the actual tracks and sectors on the drive.

 Reliability
 -----------
 Mean Time Between Failures (MTBF): 800,000 Power On Hours (POH),
                                    typical usage

Preventive Maintenance (PM): None

Mean Time To Repair (MTTR): 30 minutes

Start/Stop: 20,000 cycles (minimum)

Defect Management
-----------------
The Grand Prix XP34301/32151 allocates four sector per cylinder as
spares. In the factory, the media is scanned for defects. If a sector
on a cylinder is found to be defective, the address of the sector is
added to the drive's defect list. Sectors located physically
subsequent to the defective sector are assigned logical block
addresses such that a sequential ordering of logical blocks results.
This inline sparing technique is employed in an attempt to eliminate
slow data transfer that would result from a offline defect sparing.

If more than four sector is found defective on a cylinder, the inline
sparing technique is applied only to the first sector. The remaining
defective sectors are replaced with the nearest available spare
sectors on nearby cylinders. Such an assignment of additional
replacement sectors from nearby sectors rather than having a central
pool of spare sectors is an attempt to minimize the motion of the
actuator and head that otherwise would be needed to find a replace-
ment sector. The result is minimal reduction of data throughput.

Spindle Motor
-------------
The Grand Prix XP34301/32151 spindle motor is a three-phase motor and
is responsible for spinning the disks at a rotational speed 7200
0.1%.

Back-EMF communication technology (Hall-less design) is used to drive
the motor. The spindle motor is Y-wound, with the center tap
(neutral) brought out. The motor contains 12 poles and operates as a
three-phase device.

Hardware Requirements
---------------------
Grand Prix XP34301/32151 hard disk drives are compatible with host
computers and controllers that provide a SCSI, SCSI-2 or SCSI-3
interface.
