I'm guessing you're talking about a ps2 game. Backing that one up might be a little difficult from what i've read here: http://www.ps2nfo.com/ If you go into the " ps2 dvd rip chat" forum you'll find a thread that has over 100 replies, so good luck with that one. From what i've read if you don't have the whole game on one disk you won't be able to finish the game. If you're not backing up a ps2 game ignore all of this.
