Basically, we flashed our Xbox 360 with a Samsung Toshiba MS28 drive using IXtreme 1.4 Firmware. We burnt off a game (Mirrors Edge) using the Xbox Hack Pack. We also tied an elastic band on the railing that the laser runs along to prevent it reading the center of the disk (To check if its an xbox disk or not) But unfortunately when we put in the copied Mirrors Edge disk in the Xbox it constantly gives the error "Play DVD" then "This is not an Xbox 360 Game etc.." It plays most normal games first time, other games that arent copies it sometimes gives the same error but eventually plays the disk if you open and close the tray repeatedly to make sure it re-reads the disk. It'd be good if i can get feedback from anyone that has experienced this problem before and if anyone knows what exactly the problem is. I think it might well be a ****ty old disk drive that needs replacing or may of Flashed the firmware slightly wrong. Anyways thanks in advance.
