Have you tried the Floppy cable the other way round on this drive?
Maybe it does not have standard i/o - worth a try.

James,

Is that really safe? I don't know the pinouts on the floppy cables, but
I'm
leery of turning it around. I've never heard of anything like that. Have
you
done it? Did it make a failed floppy work? Did it make a working floppy
fail? Did it have no effect?

Do not reverse the smaller power connector. If the data connector is
reversed and is wrong the light on the floppy will stay on. OUtside of
maybe some bent pins it will not cause any harm to the drive or computer.
Some cables did not have a hole for a pin near the middle of the connector.
