I recently flashed my hitachi 78fk drive and bought a pioneer 111d drive. I'm trying to use the hotswap method but so far it hasn't worked. When I try to use Wxripper and find the magic number, it says error: no media loaded, even though the 360 disc is in there. Is it absolutely necessary to have an 8+ gb disc, because the biggest one I've used has been 7.8?
