Model numbers that end in "WD" have differential I/O
circuits and these drives and "WC" model drives have
no provisions for terminators on the drive PCB. The
system manufacturer must provide some external
means of I/O line termination. The Hawk 1LP family
"W/WD" model drives can provide power for external
terminators if the TP jumper is installed on the last
position on the right end of J2. See Figure 3a.
Read/Write head auto-park
Seagate disc drives described herein mentioned in this
drive park the heads automatically at power off. This
feature requires no operator intervention.
Optional parity bit enable
Some systems require parity bit checking. Consult the
system documentation for the specific requirements.
See figure 3a for location of Parity Bit enable jumper.
Jumper-installed enables parity reporting by the SCSI
bus.
Write precompensation and reduced write
current
Not required on Seagate SCSI Interface drives covered
by this manual.
