[PLUG] Hard drive crazy?

My Ubuntu work station (10.04 LTS) stopped recognizing the PATA CD/DVD burner yesterday.
The system also has a CD/DVD reader [PATA] and two hard drives [SATA]

I wanted to burn a DVD and I JUST HAPPENED to have a OEM SATA CD/DVD Burner still in the factory wrapping sitting on the floor.  I shut the computer off, pulled the old burner and put in the new SATA burner.

SURPRISE!!! the system would not boot.

perl -e 'print "[EXPLETIVE DELETED]\n" x 10E2 '

=======================================================
  Gave up waiting for root device.  Common problems:
   - Boot args (cat /proc/cmdline)
     - Check rootdelay= (did the system wait long enough?)
     - Check root= (did the sytem wait for the right device?)
   - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/disk/by-uuid/6ff716ef-308f-4103-a538-7aa61708f781 does not exist - Dropping to a shell!
======================================================

I unplugged the SATA burner and was able to get to the GRUB boot menu but it would not boot from the "normal" kernel selection so I selected "recovery" and told it to fix GRUB.  Now, it booted and here I am... a bootable system with no CD/DVD burner.

When I look at the /dev/disk/by-uuid directory the "missing" drive is there...

lrwxrwxrwx 1 root root 10 2011-10-31 20:59 /dev/disk/by-uuid/6ff716ef-308f-4103-a538-7aa61708f781 -> ../../sdb2

I thought that identifying hard drives by UUID meant the order of the devices/connectors is irrelevant!?

Okay, so what's the "secret sauce" for adding/moving/removing drives in a modern Linux system?

I miss IDE0, IDE1, primary, and secondary - and little jumpers.
