Thanks for the response, this helps me a lot... My answers are inline:

I figured as much, which is why I'm going to re-build the whole array with a
new drive, etc... Fortunatly I got all my data off ok without any issues.

Yes, and when I re-build it with will be RAID-5 rather than just RAID-0

Actually the only thing that was on the array was a DB, so I think the
failure may have been causing MySQL to go nuts, and cascading up.

Of course I have backups!! Never work without them. I'm going to re-build
with RAID-5 this time.

I wasn't aware 5.x could do this. My next question is how are my existing
apps going to be affected by upgrading to 5.x? I have some builds of
packages that were done by a company that is no longer in operation. I
haven't fully figured out how they built the software yet so I can't
re-build under 5.X yet. If I try to put the elf binaries and the other
builds from 4.X on 5.X are they going to run ok or do I just need to give it
a try? Would you suggest going all the way to 6.x or sticking with the 5.x

Yes, this would help a lot!!!
>How old are the drives, if you know?
They're less than 2 years old, and still under warranty. This is the second
drive to fail and it's driving me nuts.
They're Maxtor DiamondMax Plus 9 6Y250P0 250 GB PATA drives... Never had a
problem with that particular drive until this batch.
Can anyone suggest some good 250GB PATA drives for me to use? I might as
well swap them all out since I'm starting over. The 6000 series Escalade
card I'm using doesn't support anything more than 250 GB.
Thanks all again!!!
