I recently formated my external hard drive by mistake and now I'm re transfering my games back to my hard drive. Overall is going good but my super smash bros brawl cd is soo scarched I can't backup or play it freezes all the time. I was wondering what was the diffence from the backup which is 7.09gb to the 4.38gb that anyone can get online. Since I play brawl a lot will getting the 4.38gb effect the gameplay?
