In cases like this, I go to a friendly disti for data.  Try calling Arrow,
they distribute Seagate (and thus Imprimis/whatever)

pin 1 

SCSI ID is binary, factory default is drive 1.

If drive is not to be terminated, remove SIP resistor packs (3).  If drive
is terminated, insert a jumper in position 1 or 2 as shown near pin 1
above.  1 (vertical) means terminator power comes from drive.  2 (horiz.)
means power comes from cable.

Unmarked pin is reserved.

Yes, I realize there are only 8 jumpers shown here.  This is from the
manual I have and it doesn't quite match the drive.  I believe that one of
the end pins is reserved.  You'll have to orient yourself by way of
knowing what the factory default jumpering is.
