Okay, I just bought a premodded Xbox from a friend, to complement my first one, both of which have Chameleons. Mine has a blue LED, and his has a red LED, though both work... kind of weird. However -- I currently have a 200 GB HD in my Xbox, and it works fine, my old HD was an 80 GB WD800, which doesn't work in his Xbox. At the same time, I just plugged it into mine, and it works fine. With his, it gives me error 06, saying the HD cannot be unlocked. I'm going to try to lock it with ConfigMagic on mine, so I can stick it in his and see what happens, but does anyone else have any suggestions?
