My nephews 360 has just started displaying this error message. Anyone had any experiences with it? It RRODed a few months back, sent it in for repair and it's been working great ever since until this popped up this evening when he switched it on. I've read what it means and it sounds like the DVD drive has gone maybe, according to the docket he got back from MS they replaced the drive. Is it a bad repair maybe? edit : Nvm, he unplugged everything then set it up again and it's working fine.
