They both started with a Redhat5.1 disk, and have had lots of package
upgrades since. They are now running 2.2.14 kernel and helix-gnome.

root of all this....I'm an idiot who didn't update the symlink from
/dev/cdrom when I was swapping the drives around before the move. This
one's OK now. The CDRW is still not working....../dev/cdrom is linked to
/dev/hdc and the drive is secondary master. I have the modules sg, ide-scsi
and scsi_mod loaded.
