Ubuntu & RAID

[Jacob Piotrowski]

Stephen,

Most "hardware" RAID controllers on motherboards are in the end controlled
by software inside of Windows XP and not true hardware RAID controllers. 
I have run into this in the past.  I know there is limited support in
Linux for some of these "hardware" controllers, but support is very
limited and flaky at best.  If you Google the model number on your RAID
controller and Linux you maybe able to see if their is support for it.

Your best bet is to add another drive to your machine (drives are cheap
now anyways), leave it out of your RAID and use that for Linux.  If you
want RAID for your Linux on the cheap, get two small drives and use the
Ubuntu Alternative Install CD.  This will allow you to configure a Linux
software RAID, which in my experience works pretty good!
