generic disk failures ...
- use SMART, enabled in the kernel and in the bios
- disks doesn't fail as often as a power supply
-- hint.. add a nice fan for each disk
none of the "onboard raid" stuff worked in the past ... as far as i'm
concerned
if you use hw raid, you're stuck with the sw they give you to
maintain/watch yoru raid system ...
if you use sw raid, you can do anything you want imaginable
within reason to baby sit your raid box

my test for a "acceptable(working) raid system"
- install raid
- make sure yoou use FD raid partition type
- (1) power down, unplug /dev/hda
- it should boot
- write a 2GB file to the remaining disk
wait for it to finish
- (2) power down, reconnect /dev/hda
- watch it automatically resync the 2GB file
- power down, unplug /dev/hdc
repeat (1)
- power down, reconnect /dev/hdc
repeat (2)
.. repeat for each disk ...
