So i just bought Dragon Age. One day, I wanted to inspect the beauty of my paintjob (Since i painted my xbox), and i titled my xbox while the disc was inside.spinning.God im stupid!! I heard a horrible chainsaw like sound and i opened the disc tray as fast as i could. The once flawless disc has a scratch that runs around 3/4 of the circumfrence of the disc. I throw it into my box and it begins to load, then starts creating this grinding sound that pulsates every 1 second or so. Anybody have any ideas on how to fix this problem? I tried shampoo and trutle wax, neither has worked.
