Ok, I have a WD740 74 gb hard drive that I got from a friend after he parted off his computer. The problem is that this hard drive was in raid 0 (stripping), so that now when I connect it to my motherboard, bios recognizes it, when I go to check hard drives on my computer in windows 7 it also recognizes it has a 70gb harddrive, however when i try to install a fresh copy of windows 7 on it, it doesnt even appear on the list of hard drives? I dont know what to do to get it to work, if anyone can help please do!!!
