A friend of mine was wondering if this is possible. He was wanting to put a 300GB drive in a 360, but he wasn't sure if it was doable. Is it possible? I realize it would probably be some kind of warranty violation, but since MS always asks you not to include the HD when you send a 360 in for repairs, I thought it may not matter.
If it is possible, are there any consequences of doing so? Does MS have a way of knowing? Does it harm your Live subscription (didn't know if MS probed for this kind of thing)? What kind of HD would he need?
