Hey I used to have a Xbox 360 Pro with the original 20GB HDD. It broke and I got a new arcade system and switched over my HDD from the Pro, but now I am out of hard drive space. I was wondering if I could backup my games and then replace the 20GB drive in the enclosure with a WD 2.5" 250GB SATA 5400rpm hard drive and would it work on my 360 arcade?
