Does anyone know where I can find the correct software to format an HD to work in an Xbox? My current drives are filling up with all the DLC for Battlefield and Halo 4, and MS no longer sells the non-slim drives. I tried a used one, but the one good 250GB one I found didn't work and I had to return it. I have a 250G, 2.5" SATA drive, but I couldn't find all the software needed to format it. Any help would be appreciated.
