In this case, I installed a fresh firmware image on the drive, didn't 
lose a byte, but the UUID was changed, discovered when amanda couldn't 
find its virtual tapes drive after the reboot. I checked the fstab, then 
ran blkid, and it had changed. So I applied a label to the partition, 
edited fstab, and its been 69,600 or so spinning hours since. I've 
updated the system from ubuntu hardy to debian wheezy, no change.

One of these days I need to convert it to 64 bit. Probably by putting 
most of that stuff on the amandatapes partition, putting in a fresh 1T 
drive, and installing a 64 bit jessie. Once thats running, I have a 2T 
drive that I'll format for amanda and swap this one out. Nothing wrong 
with it, but I keep adding more machines to the disklist. 7 now.
