This drive uses a Centronix 50-pin connector, doesn't it? So you are converting
a 50-pin device all the way to a 50 (or possibly even 68-pin) connector?
If so, I'm sure your problems likely stem from that. That, in conjunction with
your other CD errors, leads me to believe you've got a serious termination
problem. Go over all your devices and make sure cable lengths and termination
is properly set.
If your still having problems, or sick of pulling your hair out, spend a few
bucks on an additional cheap IDE or even PCI controller to drive your external
devices.. Works beautifully.
