Ive got an xbox 360 premium which came with a 20GB hard drive. its been fine but now that a year has passed its pretty full. i want one of those 120GB HDDs but there $180(seriously WTF?????) and now im wondering if its possible to crack open the hdd case unplug the 20gb and plug in a new one. That seems like it would work but microgay being microgay they probably put some gay file that you have to have or they formatted it in some weird way. anyone know if this is possible?
