There is a message up on abit's site telling to backup all drives before usind new bios. Well when I updated the bios it wasn't there, and after using it for a week suddenly my raid 0 array disappeared. I was able to create a new raid arry and used fdisk /mbr to get back my c drive, but ended up scratching that and just doing a complete fresh install. Why did it happen after a week of more? Anyone else have this problem?
