I have a new MSI K7N2 Delta-ILSR mobo with onboard Promise 20376 raid controller. The board has two SATA plugs, and supports 2 seperate IDE 133.
I've setup the new machine to use two WD SATA Raptor 10000rpm, 76gb drives for RAID 0, using the built in Promise controller. The setup is not done in the bios itself, but in the automatic utility that follows on every bootup.
I installed the system fine, set up the array, and installed a fresh copy of windows XP smoothly.
The problem is that the raid array randomly goes offline, usually after a few hours of use and a couple reboots. Sometimes it will occur after a winxp system crash (not sure what's crashing, if it's the raid or another issue-- it's a blue screen of death and automatic reboot).
On reboot, the raid is offline, and in the raid uliity it shows one of the two drives still in the array, and one of the drives is marked as "FREE". They should be be in the array for it to work. The only known solution I have now is to delete and recreate the array and reintall XP, which is obviously not possible every few hours.
Since the machine and all parts are new I would like to think it isn't the hardware. Is anyone familiar with this problem or a solution?
Thanks for any insight.
