I was recently given an original Xbox by a friend of mine. The console was rather dirty when I received it, so I took it apart and cleaned it all out and wiped down the lens etc. The system has been working great and playing any game that I've thrown at it for the past month. Fast forward to about a week ago when I went to go play a copy of Baldur's Gate: Dark Alliance I purchased off eBay. I throw in the disc and immediately get the "disc is dirty or damaged" message. I figure it was probably the disc since it had some visible scratches on the surface that were quite deep, so I sent it back. I quickly get in a second copy, throw it in the Xbox, and same thing. This disc also had some pretty bad scratches so I figure it's probably just my luck with sellers on eBay. I decide to purchase a third copy and sure enough I get the same message as before. Yet this disc is near flawless. So I'm a bit puzzled now as to why my system won't read this particular game. I've played close to 10 different games since I've had the Xbox and have yet to experience any other problems. The only thing I had happen was Jade Empire froze once during a long session of playing. Is my disc drive to blame? Thanks in advance!
Edit: It sounds like it could be a laser calibration issue. I'll try the "pot tweak" fix and update once again.
