I had a an xbox elite 20gb, i then bought the 4gb slim. I took the hdd from the elite and put it in a caddy to slot straight into my slim. The slim recognises it as a flash drive. Can someone please explain (in laymen's terms) how i format it to work in my slim as an internal hdd. I know it can be done as long as the hdd is compatible (which it is as i took from an elite). Really need help guys!
