I think there are ways that drives can fail that would make them not be detected
at all - and for an autodetected raid member in a system that has been rebooted,
not leave much evidence of where it was when it worked. If your slots are all
full you may still be able to figure it out but it might be a good idea to save
a copy of the listing when you know everything is working.
