One thing to watch for are the little 20-way Apple
ribbon cables that
link these drives to the mainboard. They are not what they seem -- in
particlar 1 ro 2 wries are not wires at all, but solid plastic, so those
pins of the connectors are not linked. If they are, then all sorts of odd
things happen (Eject motor runs continuously???)
I beelive there are at least 2 versions of the calbe (for double sided
and high density drives>?, with different coloured pin 1 tracers. A Mac
enthusiast may know more.
I don't remember all the details. I do remember that there is a cable
with a yellow stripe on pin 1 and another version of the cable with a red
stripe. If you install the wrong cable (can't remember whether it's red
for yellow or yellow for red) the eject motor does indeed run
continuously.
It doesn't seem to damage the drive; I never let it run more than a few
seconds. So it's easy enough to identify and correct.
