Sean, Casey, and Derek:

Thanks for the replies so far.

Yeah, I stay away from things that say "Initialize", "Delete Array",
etc :). Part of my concern came from the fact that I got a kernel
panic the last time I tried to boot into FreeBSD, but that may have
been because one of my disks was disconnected and the bzero attempt
was polling some address out of range (I was attempting to
troubleshoot the issue at the time).

I'm pretty fed up with Intel's ICH9R interface too so I'm hoping
(crosses fingers) that I'll be able to afford an Adaptec card of some
flavor that's compatible with -CURRENT. For that I'll ask for advice
on current@ later on which card to get...

It looks like my figuring out what to do in solving this issue will
only be solved by grabbing another drive and replacing the dead one.
Oh well, here goes for an RMA...

TIA,
-Garrett

If you are looking to move up, look at the 3ware RAID cards. Not sure which models work with FreeBSD, but these card do perform very well.

I'm happy with my HighPoint RocketRAIDs. HPT's site has the drives and they work in 7.
