My problem is this:


My XP Pro OS (SP3) can no longer access my raid1 drive.


In the disk manager, it shows it as a foreign disk.


When I right click to reactive, the disk window wants to change it to simple. I said okay, but it bounces back saying no can do. Upon looking into the system event log it says” INTERNAL Error - A disk group with the specified name already exists (C100007A).”

I need to be able to access this drive from both OS's, How do I fix it? (This is my first time with dual booting.) So I'm a newbie I really could use some help, please?


Background: I have been running my XP pro for years on this Hard disk with a raid 0 no problems. I just set up a dual booting system by adding Vista 64 on a separate hard drive.

I change the raid from a raid 0 to a raid 1 using new drives before loading Vista.( Raid drivers were already loaded and working on XP) Then I loaded the Intel raid matrix storage driver(64bits) on Vista during install.(F6fpy6488 )

All drives are available on Vista and working normally, but now the raid 1 drives (two 1TB drive mirrored) are no longer accessible by XP.


System:
Asus P5B deluxe bios 1238 Sata set to Raid
Cpu intel E8400
4gigs ram
XP Pro SP3 and Vista Ultimate 64 SP2 each on separate 250gb seagate hard drive.
Intel matrix storage 8.8
Boot manager is working fine.
