It sounds like pin 34 on that drive has been disconnected.  There's a
jumper on some drives (I think TEAC labels it XT) that must be connected
for the drives to work on the UNIXpc (or a PC/XT).  If you can't find the
appropriate jumper and you have a multimeter, set it for resistance,
place one lead on pin 34 (this is on the card-edge connector - back of
the drive), and test the jumper pins until you find one with no resistance.
Jumper this one.  If there are three pins, move the jumper to connect
the middle pin to the one connected to pin 34.

If you're still having problems after this, let me know.
