If your on 360 and your game keeps crashing you shouild try installing it to the hard drive, however if your disk is damaged then this might not work, BUT if u just borrow or rent someone else's game you can use that instead to install the game then once u return that just start up the game with your own disk and it will just run from the hard drive.
I highly recommend you try it even if you think ur disk is 100% scratch free.
