Internal hard disk drive (40GB) (for PlayStation®2) (HDD) installation will change the way you store and manage saved game data on the PlayStation®2 computer entertainment system. The biggest change is the addition of folders that can be used to store saved game data on the HDD. The HDD also changes the options you have for handling data on a memory card (8MB) (for PlayStation®2).
NOTE: Deleting saved game data will completely erase it from your HDD or from a memory card (8MB) (for PlayStation®2). Proceed with caution as it might not be possible to recover saved game data after it has been deleted.
