Hey, Having a weird problem with my V 0078fk drive. Its not flashed. Right when i put my "backup" dvd in it made a serious grinding noise and then said "unplayable disc" I opened the drive ip to find: Bear with me this is hard to explain. Right you know on an xbox 360 drive their is the sticker explaining what drive it is. Above that theirs like a cirle. Underneath that cirle there was a white cirle thing with a magnet thing on it loose and wobbling around. Could this be the problem? If so how do i refix it? P.s just tightened the screws and when trying to play the dvd again it still grinds but works after a few secs of grinding. Any help would be much appreciated!
