This started happening a few months ago where the cd drive wouldn't read my discs every time so i would just eject the disc and try again and after a few tries it would work. Then last week i realized it has been taking longer and longer to read the discs and now can take up to 20 minutes. So i decided to buy a new cd-drive and put it in to fix the problem. Today i put it in, but the problem persists. I have the original 20 gb white xbox 360. Any ideas on whats wrong.
