Ive had my xbox for about 2-3 years now.. and very recently it just started not accepted certain games.. I recently re bought Gears of War 2 and it runs the game and then states "Open Tray". So i thought the disc was unreadable so i took it back, and i got the same response. I searched up everything and went to the support and tried everything. It only works if the hard drive is out.. but the doesn't make sense because I'm able to play almost every other game with the hard drive in. So do i need to be a new hard drive or am i able to buy a refurbished one. Or is there a way i can fix this? Thanks in advance.
