had to fix my xbox 360 myself, stopped reading disks, disk errors from hell, called microsoft, but they told me it was not covered and it would cost me $99 and take weeks, so i went to google and youtube, found out how open it up myself, only to find the the problem was the little magnetic ring on top of the dvd drive which should have been glued into place, had come off because it was not glued at all just shoved into place, so i simply got some crazy glue, glued it nicely into place and everything worked. they should have called it crap box 360. or all around crap box.
