It's a hardware RAID controller, transparent to the OS. I don't know
precisely what model off the top of my head, but considering it's a Dell
rack-mount server, it's probably a Dell OEM device of some kind.
Server OS is Windows 2003 Server R2 Enterprise.

Replace the batteries on the RAID controller.

You think failing batteries would cause one partition on the RAID volume
to persistantly suffer NTFS corruptions, but the other (much busier)
partition on the same logical volume works correctly?
Hmm, I wonder how much money Dell want for a new battery? ;-)

It may not read and write the same number of bytes, but as far as the
number of IO requests go, the system partition is probably as busy as
the other user data volumes. Event viewer logs, DLLs loading, swap file
usage, etc...

I don't know about Dell RAID controllers, but on the ones I've seen
(Compaq (back in the mesozoic era), HP and IBM) they were standard
batteries that you can find in most electronic stores (e.g. Radio Shack
in North America)
