I try to install disc 2 and a pop up comes up saying "Unable to write to your gamer profile. Please make sure it is not on a removed storage device or on a storage device with low space" Well, I got a new hard drive planning on installing all my games, so I have space available. But then the gamer profile, should that be saved on my xbox memory space or on the hard drive? At one point, it was installing, but a fourth of a way in the pop up appears again. The game is used, does that have any importance?
