My cron runs this, once a day:

#!/bin/sh
# Set clock
ntpdate tick.jrc.us
/sbin/hwclock --systoh
# E-mail when a raid drive fails
cat /proc/mdstat | grep '1/2' | mail name at domain

If I receive a non-empty e-mail, I know one of my two raid drives is 
in distress. If both fail, well, I find that out soon enough... The 
file also resets my hardware clock.

Your mileage may vary :-)

Joe.
