my xbox 360 has a problem. The disk drive opens immediately after being closed. I even tried closing it and then turning it off, but when I turn it on it opens again. I searched for an answer to this problem, and found the issue most users are having is inside their disk drive the magnet became dislodged, causing an error. I opened up my xbox and had a look, and the magnet was still in place. is there anything else that could be causing this?
