Recently our hard drive went crazy for no reason. my brother was playing halo reach, he turns off the xbox just like normal, leaving the game, nothing saving, turning off by holding down the xbox jewel. next time we turn it on, about 5 minutes later, the xbox stays on the start up picture that say "xbox 360." when we finally get past that, we don't have any gamer profiles, no downloaded games, no DLC. anything on the xbox memory is fine, but we transferred most of our stuff onto the hard drive, which now says its unformatted. we don't want to try formatting it again, since we have about $50 worth of DLC. we got an update after we tried rebooting it that we downloaded, but it still is unformatted, but the update may have caused the unformatting. any way to fix it without losing everything on the hard drive? PS: its an official Microsoft hard drive as well, and we haven't done any modding or the likes at all.
