I found out the RAID controller was using a Via 6410 chipset, which I
have discovered is the bane of many linux users who ended up in the same
boat.

The place I had build it has swapped the mother board for one with a
Promise controller, which has drivers for RedHat 8 and Suse 9.0.

I am really leaning toward using software RAID, so should I put the two
drives on the same controller?

IDE RAID controllers are bogus, their really pseudo-software
controllers.

Fedora... well, okay, maybe there'd be a reason to stay with RedHat, but
if you go that route you should be using their server line and paying
for a subscription. Otherwise you should just use Fedora.

This probably has something to do with the silly IDE RAID controller.
You can find instructions for bypassing the RAID and then set up linux
software RAID. I'd really recommend that route.

Unless I'm mistaken recent versions of the kernel bypass the RAID stuff
by default on many IDE controllers (because it's not going to work
anyway). Fedora should do this for you... it did for me... I think.

Software RAID is really good though, it has very little overhead and
it's somewhat more flexible. Even hardware RAID (especially fake IDE
RAID) has overhead, so your not missing much there.
<http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html>

Or there's information on getting the IDE RAID to work anyway here:
<http://www.tldp.org/HOWTO/ATA-RAID-HOWTO/index.html>

Also, I wouldn't rule out the possibility of a bad drive, especially if
it's new. Most drives (most anything, really) either fail the first day
or just after the warranty is over.

Another thing: Is it SATA? If it is then try Fedora. Earlier kernels
don't work right with most SATA.
