Well I think it was COD4. I've just installed it, having been unable to wait for Santa tomorrow. At the beginning of the second mission, the game locked up (no error message or anything, just froze) and I restarted my pooter. Upon coming back into Windows, I seem to have lost my D: drive, which is my second SATA hdd. The BIOS doesn't recognise it either, but it takes a while (much longer than usual) to decide what HDs I do have. Any ideas?
