I've had this problem with 500GB WD Blue Caviar drives. It happened for me when i was using a slim and did not have a DVD drive in it all together. I thought doing the DVD check fix would work but it still did the same thing. Popped in an older drive and booted up just fine. I narrowed it down to the hard drive, kinda sucked but i just had to use it in an xbox with a DVD drive. This has happened to me 3 or 4 times with those new WD drives.
ah i see well thanks anyway fiend, and indeed it was a new WD hard drive
