I purchased a 120gb harddrive from Gamestop to go along with my Arcade Xbox and the harddrive only showed up as 16gb, I took it to gamestop, they gave me a new one, same problem, I called Xbox, and they told me I needed a newer model Xbox. And today, about 7 months later, I buy a Slim, and same problem after formating and everything. Is there anything I can do? I looked everywhere, the only tools I have at my disposal are a Transfer Cable and a set of Torx screwdrivers.
