I work at a game store that fixes problems with newer systems. The xbox has a problem with the lazer burning out around now i have had to replace no less the 20 this week. something that can help with it not scratching your disks is to lay it flat and not to stand it up this help vent out he heat also to avoid the red ring. I will say that sooner or later your going to burn out the lazer its only a matter of time. Most of the drives are synced with the motherboard so if you do try to replace it only replace the lens or it wont work. as of the game viewtuful joe dante and zero seems to be the team im best with but i like the faster people anyway.
