I Have Only Played Halo 3 A Couple Of Times. But My Xbox Already Gave It A Big Ass Scratch Along The Outer End Of The Disc. My Xbox Can Still Read It But When I Goto Load A Map It Says That "I Failed To Load The Content." I Have Turned Off My Xbox. Tryed Multiple Maps. But Still No Luck. So I Was Wondering If I Installed It To The HDD Then Would It Possibly Work?
