Out In = Drive supplies power to its own terminators if used. (default)
In Out = Drive supplies power to SCSI bus; not to own terminators.
In In = Drive supplies power to own terminators and SCSI bus.
Out Out = Drive supplies no power.
Pin 2 to Pin 4 = Drive gets term power from SCSI bus.
Seagate ST39205LW and ST318203LW:
1 Out = Drive supplies no power to SCSI bus. (default)
In = Drive supplies power to SCSI bus.

NOTE 1: The drive may be installed in one of five
orientations, either PCB down or on any
NOTE 2: For a Compaq drive, the spin up delay for
each drive is 10 sec x SCSI ID setting. Therefore, if any
of these drives are configured for SCSI ID 2 or higher,
you will need to insert a SLEEP command just prior to
the SCZDSP command to delay execution of the
SCZDSP command long enough for these drives to
spin up.
