I have a 20GB hard drive but I can't get it to format. I can get it to load up the 360 dashboard with the hard drive in but it literally takes over 2 minutes to boot the dashboard, the hard drive shows up and says how much memory is left but when I click on it, it temporarily freezes and after it finally loads is says 0KB has been used for anything. I've tried to format it but after a minute or so it says it can't be formatted. It's a Hitachi. I also have another drive that just tries to spool up over and over but it doesn't get anywhere. This one is a Fujitsu. Any ides on how to fix either of these problems?
