After fixing my Xbox 360 after trying to perform the Kazekami Hack. I noticed that some games make a loud screeching noise, and the game will lock up..needless to say it doesn't sound healthy at all. I backed up my copy of Sonic Generations to do a comparison of a burnt copy to the original. And the original disk runs just fine...however the burnt copy sounds almost like someone taking a knife to a chalkboard..I am using verbatim 2.4x with the Extreme Burner using Imgburn.

With the same type of disk, Halo Anniversary works just fine.

Any ideas? (Installing the game to the hard drive doesn't do anything, for some reason it still loads from the disk...believe me you can hear it lol)
