With my thinkpad, I find a utility called "idectl" usefull. The
expansion tray can take an extra ide device which is helpfully on the
second IDE channel - idectl can turn that channel on off (ie force
detection or drop a detected drive) allowing me to suspend and
change/add/remove the tray or drive.

Can of worms that. I just make sure nothing is mounted and that ide-scsi
/ ide-cd are not loaded when I do 'idectl 1 off' and suspend.
