FS corruption is no fun (I once spent two days recovering data
after bad RAM corrupted an ext2 fs... I ended up with every file I had
in lost+found). But the particular failure I mentioned was drive
hardware, no doubt about it. Lots of low-level IDE errors in
/var/log/messages. Couldn't fsck it, couldn't get any raw
data out of it with "dd if=/dev/hdb", nothing.
I didn't have any warning, either... no funny noises, no
problems or errors the last time I mounted it. *shrug*
+1 on the UPS idea, I've had one for years.
