I guess Ubuntu has moved to libata, and so all disc devices are now /dev/sd*
devices, even if they're EIDE/PATA.

Showing us what your new fstab looks like would help if you want guidance
here. Red Hat and Fedora use filesystem labels in their fstab by default. I
guess UUIDs are a bit more foolproof, if one connects multiple volumes with
the same filesystem label.

Eh? That makes no sense, unless you're keeping your drivers in non-standard
places. If so, this is why fitting in with your distro's standard locations
is a Good Idea.

Check the output of 'mount' and you'll be able to see how your other
partitions are mounted. My guess is that your data partition is /dev/sda5,
but your previous mount point naming convention is bizarre and confusing.
