sorry dude but no you cannot. the reason is because xbox games are written with bad secters that cannot be read or duplicated by any dvd drive that you can get ahold of. some games will read in your pc, but it will be in a dvd movie format because dome games are dual layer and one side is the movie of the game, and the other side is the real game. a normal dvd reader cant read that other layer sorry. ur out of luck. if the xbox doesnt read the disc, there is NO way you can back them up
