So I just got my Xbox 360 slim hard drive (I have had Reach before I got it) and plugged it in. Co-op play works fine and everything but when I try to access theater, file share, or my temporary history, it says that I don't have a hard drive (when I obviously do!). I've seen other people's posts about how the problem is about your privacy or parental controls, I tried that anyway but that's not problem. Can anyone help?
