FTP everything from HDD0 to the PC. Thats what I've done. I will be updating my HDD very soon. It's only a 250GB and its full. I have to keep deleting older games installed data just to play new games.
Does this work for PSN games too? I got all of them backed up but if I FTP them back to the new HDD will they be playable? If they cant then I might as well just wait till a CFW comes out with PSN access then update the normal way and re-download everything from PSN.
