I just bought a 20gb xbox360. When I start the console, however, I cannot create a new gamer profile as it keeps prompting me to select a memory unit. I try to press continue but the screen stays there and the console cannot detect the hard drive. I've already attached the hard drive to the console time and again but it just won't work. Now I can't play my Mass Effect and Lost Odyssey because I won't be able to save. Please help a desperate gamer : (

Any help would be appreciated.
