The SS jumper enables the self seek function. Install a jumper and the drive
will execute butterfly seeks endlessly or until an error occurs. This is a
test jumper.

The EP jumper enables parity checking by the drive. Note that most scsi
devices generate parity. The jumper option offered to you is to check or
not to check. 

The WS jumper enables the wait spin function. With a jumper installed the
drive waits for a software command before spinning up. With no jumper in
the drive spins up when power is applied.
