In Gran Turismo 6, replay data, ghost data, photo data etc. are stored in your game data, not in your save data. If you do not have enough space on your Hard Disk Drive (HDD), you may not be able to record, save, or access this data.
If you delete your Gran Turismo 6 game data using the PlayStation®3 system's XMB™'s Game Data Utility option, your replay data, course data, photo data etc. will be erased, so please be careful.
You can copy your Gran Turismo 6 save data to external media, such as USB drives.
