Clarification:
If I ever DO have to use the backup (because the "main" IDE goes bad),
the IDE disk in the USB enclosure (/dev/sda while in the USB enclosure)
will be removed and placed in the main box thus becoming /dev/hda !  So,
what I need to do is to insure that it will be bootable as a regular IDE
disk when that happens.
