That's not what I mean by a full RAID failure. I've had plenty of disks 
fail and subsequent successful rebuilds. I'm saying on one occasion 
(because of an oversight) I ended up with an unrecoverable RAID 5 
because of disk failures.

Of course, this wasn't a serious problem because I also had backups.
