I tried the delete the game data for GT5, but instead of disappearing, it changed to 'Corrupted File'. When I try to delete this, it just says 'The system storage cannot be accessed.' When I try any of the options in safe mode, it just says 'Preparing...' forever. When I try to back it up to an external hard drive, it says 'Preparing' and then throws up an error message. Everything else works fine. Please help!
