The other day i turned on my Xbox 360 and no profiles were found, So i went to settings then memory and it says my hard drive was unformatted. So i entered my serial number and formatted my hard drive. After i did that i restarted my xbox and went back into memory and it still says unformatted. I repeated the formatting process mutiple times now and it still says unformatted any ideas on how to fix my hard drive???
