I have a 80GB PS3 that I got for Christmas in 2006. Over the years I got like over 30 games, 130 songs, and 4 movies on it. A couple of weeks ago I wanted to downloaded the Starhawk Beta but got a message that my PS3 does not have enough memory on it so I went to check the the storage capacity and only had 631MB’s left. I did delete a bunch of old games and useless stuff and did had enough to download the beta but then the MW3 map packs came out and the same message came up again. So is there any way to get more memory for my PS3 and how to back up my hard-drive to a storage device? Please help me out I want those map packs but don’t want to delete more stuff.
