If you look at the sig you'll see that I had a 640gig WD SATA HDD on the way. Well I've just gotten it and it doesn't show up under My Computer. All connections are good and Bios sees it. This is my first HDD that I bought and it's just confusing ya know? If it helps, also, it's a bare drive. Do I need to put something on there before I can use it or should it just be like a plug-and-play deal?
