Somehow my xbox put 4 small radial cracks around the center ring of my disc, and then somehow made a few tiny scratches on the surface of the disc itself. First I noticed black lines mixed in with the textures of the walls/floors of the maps. Now I keep getting the disc unreadable error. FML, FML a lot. I doubt they are going to do anything but Microsoft is going to get a very angry email about this!
