I think I ran for about 2 weeks on a dead drive. Thankfully it wasn't a
production system, but notification isn't quite as "out of the box" as it
needs to be just yet.

First, do you have ANY log messages from anything other than RAID indicating
a failed disk? Since these are IDE drives, I'd expect some messages from
the IDE subsystem if the drive really had died (my SCSI messages went pretty
wild when I had a disk fail). To check and see if the drive is actually in
good condition, grab the diagnostic utility from the support site of your
drive manufacturer, boot from a DOS floppy, and run diagnostics on the
drive. In order for them to replace my drives, I've had to do "write"
testing, which destroys all data on the drive, so you may want to disconnect
power from one of the drives before you play around with that. If the disk
is good, then you're all set. If not, get it replaced. I've seen drives
fail very quickly before, it's always been a manufacturing defect of some
kind. HTH,
