Unable TO READ HALO 4 DISC

Myself along with several others get an error message when loading up halo 4. It always occurs during the title sequence and it says disc unreadable and sends me back to dashboard. All of my other games work fine and the halo 4 disc works on the my brothers xbox. What should I do. I’ve cleaned the system cache and done everything I could to fix it including talking to a support specialist. And lastly I can load the game up with out a hardrive but with it I cannot.

I am having the same problem. I am very frustrated, I have been looking forward to playing for a long time. If you find any answers please let me know.
