Check the DS jumpers and the cable. Sounds like the controller thinks both are
A:, or the cable is reversed. The end with the "twists" (pins 10-16 I think)
should be on the A: drive, not on the controller. I've found a few "bad" machines
that supposed experts have worked on done in reverse. Also a foam swab and
denatured alcohol on the heads cleans them up rather well.
