The consensus was that I was probably out of luck, and this turned out to
be the case. I was never able to read the drive again. Suggestions included
attempting an fsck, gently tapping the case to loosen possibly stuck heads,
letting it cool, and replacing the logic board. I wasn't able to attempt the
last suggestion, though I may yet do so if I can locate a cheap one. (Anyone
have one? The is the old Quantum RZ28-E, Rev J01, from an RZ28-VA) In the
end I replaced the drive and started over, a sadder but wiser man. I'll be
buying that UPS shortly, and I'm making sure my backups are usable, too.
