Actually if I remember, the original question was more along the lines
He has a server running in another room somewhere, and on that server he's
using a RAID 1 (mirror) using the built-in RAID controller of the MB.
Somewhere down the road, IF one of the HD's in the RAID 1 array dies, the
system itself will continue to run off the remaining HD, but, how will he
ever know that one of the HD's has failed, leaving the RAID 1 array running
in a degraded state.
I believe he was asking if there was some feature of either the hardware on
the MB (RAID controller) or of whatever OS he installs, that he could make
use of to be able tell that a HD has failed and needs to be replaced.
of course this all depends on the features of the RAID controller itself and
possibly of the OS.
at the very least, you should be able to inspect the event logs (If it's a
Windows OS) to check for logged events indicating the RAID array has been
degraded due to a HD failure.
the server is in another room, so he can't see any error lights that may or
may not be flashing on the hardware itself.
RAID arrays DO 'fail'. They just allow for redundancy in various forms
(except RAID 0) , so that if one component (HD) fails, the system will
continue to operate with no data loss until such a time as you can replace
the failed component.

You're right; I was thinking about if the RAID itself failed, which isn't
outside the realm of possibility, especially with only 2 drives in the

Just a couple of thoughts...
Write a batch file/script that tries to hit the RAID array every so
and if it fails, have it send you an e-mail
Isn't the whole point of RAID ( mirroring ) that it *doesn't* fail ?
Your idea just fell at the first hurdle.
