one other thing I tried, which didn't help: I used a Windows XP CD

Read Error.

Backup your files on this machine and zero out the drive using the
manufacturers disk for this purpose. Reinstall and this time use a
smaller partition for the other OS and the standard four for
linux /boot / /swap and /home. Make sure /boot is below sector 1024 as
you had to do under lilo.

I tried reformatting all partitions and doing a complete reinstall. And I
still got the read error!

But now I have a hunch of what is going on, yet to be verified. You might
remember that I commented that the problems started after I had moved the
guts of the machine (motherboard and drives) to a new case. That didn't seem
relevant at the time. I also noted that the results of root (hd0,6) were
inconsistent, which strongly suggests that hardware is involved.

Putting all of this together, the most likely cause is that the hard drive
cable is not well seated in the connectors. I haven't yet opened up the box
to reseat the IDE cable (it really is an 80-pin one) but I shall do so
shortly. One intermittent connection and one missing connection could well
account for everything I have seen.

I've checked out the drive itself quite thoroughly -- but I don't know how to
check out the cable other than inspecting it visually. Any ideas?

I'll report back if I have more success once I've tried reseating the cable.
