that used to happen to me and i tipped my xbox back while reading the disc a few times and it was fixed. did you happen to be jumping around alot while the disc was in the tray. you might have a circle scratch.

ring up microsoft and send it to them, they will replace the cd drive with a new one.

i found a way it worked with me but it deepends how deep the scratch is follow these steps :-:

1.Get your scratched disk facing up (so the scratch is facing up)

2. Get a tub of toothpaste and run the tooth paste over every part of the the disk (make sure the toothpaste is only a thin layer but not to thin)

3.Leave for about 5 minutes

4.Now put water over your fingers and slowly rub the toothpate of gently .

5.Now leave to dry for another minute


NOTE : Any other water just rub gently of


Thanks if this did help please +REP

Sorry mis understood the question try see if the laser is in the right possition

spit on your disc and dry it with your T-shirt
