Re-seated those connecters a few times, with no results. However, after
swapping the two drives, I got them both working again. I'm thinking I
should replace that ribbon cable as soon as I get a chance... but I'm just
happy to have both drives working again. :)

For future reference, I'm pretty knowedgeable about electronic hardware,
have a 10MHz scope and other 'basic' tools, and the common sense to put
the disk in right-side-up (well, most of the time anyways :).
