Possibly a drive select issue. Some drives had jumpers or switches,
some cables have flipped-around wires so the connectors are specific to
one drive or another. If your cabling is straight-through with no funny
business at the connectors, set the drive to DS0. If the cable has
split out and flipped-over sections, DS1 should be set in the jumpers
--but then it depends on which connector is used. ...I think, anyway,
it's been a few years since I've had to use a 5.25.

None that I've seen.
