hey so I have an older xbob probably like 2 years but lately I have been noticing it is scratching my discs. On the furthest inside ring on the back of the disc there are small cuts that go from the start of the ring to the beggining of the next ring. My black ops disc had this start happening to it recently and I couldnt figure out what was happening and then it happened to my battlefield bad co 2 disc tonight both are playable to a point but they will just sort of randomly stop working and this is consistently happening. My xbox is always horizontal by the way and I havent changed anything about its set up for a year and the problem just started recently. Is there a way to fix this or is my xbox just screwed?
