I haven't followed all of this thread but looking at the info on the
ST31230N I would say that you need a jumper on j2 pin 15/16 to enable
the terminators, and also pin 3/4 to enable term power from the drive.
The big question is what to do with "PE" the parity option. Parity
needs to be turned off which in my experience usually means adding a
jumper to disable it. But that's not clear in the documents. So I'd try
it both ways, but I'd expect it to be jumpered.
The other big point is .... so this is NOT an Apple-rommed drive? If
not them you will not get the standard Apple hard disk s/w to intialize
the drive. You'll need the "patched" version from Gambas web site....

There are some extra settings on the HD i am unsure off.
for example:
A set of jumpers for terminaton power.
TP TP
Off Off-No terminator power is connected to drive terminators
or SCSI bus I/O pin 26.
On Off-Drive supplies its own terminator power only. Jumper
on this position is factory default for "N" models only.
Off On-Drive supplies power to I/O pin 26 of SCSI bus;
none to internal terminators. When drives have
differential I/O circuits, a jumper on the right TP
position may be needed to power external terminators
On On-Drive supplies terminator power to itself (internal
connection) and to I/O pin 26 of SCSI bus. This is
a legal jumper setting.
