+---------+-----------+-------------------------------------------+
SS Self-Seek Jumper
--------------------
The self seek test continuously exercises the actuator of the drive.
To enable the self-seek test, install a jumper across the SS pins.
Alternatively, the host can initiate a self-seek test by issuing a
SEND DIAGNOSTIC command, with the self-seek bit set to one.
When power is applied to the drive with the self-seek test enabled,
the drive initiates a self-seek test. The SCSI-bus device
identification (SCSI ID) currently selected determines the self-seek
test performed.
- If the SCSI ID is set to 6 (factory default), the drive will
perform random seek patterns, verifying target ID's after every
seek. The pattern will repeat as long as power is applied to the
drive or until an error has occurred.
- If the SCSI ID is set to any value other than 6, the drive will
perform a bufferfly seek pattern, beginning with a single track
seek at the middle cylinders and extending out to a full stroke
seek. The pattern will repeat as long as power is applied to the
drive.
NOTE
The self-seek test continously exercises the drive actuator until
the jumper is removed from the SS jumper pins.
ProDrive 40/80/105S drives are shipped from the factory with jumper
SS not installed (self test disabled).
EP Enable Parity Jumper
------------------------
The EP jumper option controls the checking of parity across the
SCSI bus. When this jumper is installed, parity generation and
parity checking of data across the SCSI bus is enabled. With this
jumper removed, parity checking is not performed, although parity is
still generated.
ProDrive 40/80/105S drives are shipped from the factory with jumper
EP installed (parity enabled).
WS Wait/Spin Jumper
--------------------
The WS jumper controls the Wait/Spin option. When a jumper is
installed on the WS pins, the ProDrive 40/80/105S motor will not spin
on power-up until the host sends the START/STOP UNIT command across
the SCSI bus. This permits power sequencing so that the system power
supply is not overloaded by multiple devices demanding peak start
current at the same time. Once the drive receives the Start/STOP UNIT
command, it will be ready within 15 seconds. When the WS jumper is
not installed, the motor will automatically start spinning upon
power up and be ready within 15 seconds.
ProDrive 40/80/105S disk drives are shipped from the factory with
jumper WS not installed (Wait/Spin option disabled).
A2/A1/A0 SCSI-Bus Device Identification
----------------------------------------
The SCSI bus can support up to eight devices, including the host
system. The identification number of each device determines its
priority level. Prior to installing the ProDrive 40/80/105S hard
disk drive, you must choose its SCSI-device identification number.
Jumpers installed across three pair of jumper pins - A2, A1 and A0 -
in various combinations permit the assignment of the drive's
identification number. These three pairs of jumper together comprise
a 3-bit binary number, in which A2 is the most-significant bit and A0
is the least significant bit. With a jumper installed, a pair of pins
represents a 1; with no jumper installed a 0. Thus, with jumpers
installed across all of the pins, the device identification is 7;
with no jumpers installed, the device identification is 0.
Quantum ships the ProDrive 120/170/210S hard disk drive from the
factory with the A2 and A1 jumpers installed - that is, the drive's
default SCSI-device identification is 6. If the jumpers are changed,
the new device identification takes effect at the next power on.

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.
