Particularly in this sort of situation, it can be very handy to mount
things by LABEL or UUID instead of by partition.  On the system I'm
currently sitting at, I see both in my fstab:

UUID=412768f8-9f7c-4e37-955e-a627798677a6 / ext4 defaults 1 1
LABEL=AML_BACKUP /mnt/backup ext3 noauto 0 0

This takes some of the stress out of figuring out exactly which disk is
which (although Grub isn't quite as flexible).
