Does anybody know if you play ur back up games on ur xbox 360 modded will ruin or mess the lens faster than using the original ones ? I'm asking this cause i noticed my xbox makes a lot of noice while reading, and also sometimes it makes like a little crick crick noise, somthing pretty weird, has anyone else had this ¨problems¨ too? If it is a problem! thanks!! nice question cause it will make you think about using the back up copies instead of the originals!Ignacio
