Ok, I had to put a new hard drive in a RAID 1 array where one had died. Seems simple enough right? I put it in, booted into windows, and rebuilt the array with Intel Matrix Storage Manager. It said that it rebuilt fine. Everything was working. I rebooted the computer, and windows would not boot. It kept saying that major system files were corrupt. Tried running chkdsk, it ran forever saying it was repairing, did not fix anything though. I took the original drive out and copied all the data that I needed to another location, it is not corrupted as far as I can tell, I can use all the apps just fine. I figured the raid array was F'ed and I would just start from scratch though. I made sure the bios was set to raid, created a raid volume in the Intel ROM, installed windows. When I try to boot into windows I get a BSOD saying unknown hard error. Have tried this multiple times! I have called Intel to make sure I am using the correct drivers. I can install windows to one drive and run off it just fine. Could someone please help me?
