Disk Management Missing SYSTEM Drive (Disk 0)

Running XP Pro, fresh installation (3 times) on a new computer. Gigabyte
GA-P35-DS3R motherboard, two Seagate SATA 500GB drives configured in RAID1.

Several days after successfully configuring and loading XP on this computer,
the System drive (DISK 0) DISAPPEARS from Disk Management! The computer
continues to boot fine, C: is visible and accessible from My Computer, but
not Disk Management. Strangely enough, Computer Management | Disk
Defragmenter still sees and can access Disk 0, but Computer Management | Disk
Management cannot.

Additional information: Three other volumes on the same RAID array continue
to show fine in Disk Manager as Disk 1, 2, and 3. Device manager shows the
System dirive with the correct volume name and says it is working properly;
however, if I go to the Volumes tab, it cannot populate that information
(Disk: unknown, Type: unknown, Status: unreadable, Partition Style: not
applicable).

I have Norton SystemWorks 2007 installed, and when I first put it on, it
sees C: fine and can back it up. Later, after this drive disappears from
Disk Management, Norton Save and Restore can no longer see that drive either.
Norton Utilities continue to see and access the drive just fine.

I have tried to use System Restore to roll back any MS patches and utilities
I have installed, but all restore points fail.

Any ideas? Thanx!

System Restore is most likely suffering from interference from Norton.

Is Windows XP the only operating system on the computer?

Hope this helps.
