My halo 3 won't work on xbox 360?!?!?

Question

A blank "green" screen comes up and then it says "unreadabledisc". I bought the game 5 months ago and it seems to work fine till 2 days ago because i asked my cousin to put the disc in. And i wonder if he put the disc in correctly or part of the disc was sticking out? Then i look at the disc and it has some lines but im not sure if therescratches but the lines are on the edges... My question is wat do i do?!?

Answer 1

Might be something wrong with your 360. Did you try putting another game in and see if it reads it?

Could just be your disc then. That sucks. It happened to my friend's halo 3 disc also. We were in the middle of a game on live then it just stopped working for him and he kept getting that message to.It started working again out of nowhere for him one day though when he put it in.

Answer 2

i've read that sometimes the 360 disk tray can sometimes mark the disk in a 'O' shape around the center.

hmmm...
