"Lurn to Reed, Part Too"
"Two weeks back, we spoke out about a small number of users experiencing Disc Read Errors and described what they could do to get their Xbox 360 back into fighting shape. The resolution path hasn’t changed. If you are one of the unfortunate few experiencing issues with your Xbox 360 failing to read discs, you need to contact 1-800-4-MY-XBOX for assistance. There are no Title Updates or software patches capable of resolving this issue. Replacing the disc will also not resolve this issue. It is hardware related.
We had hoped that the resolution would have been much the same as it had been for users experiencing similar hardware issues around the launches of Halo 3 and Halo 3: ODST, but it appears that those players who find themselves outside of warranty will be responsible for getting their Xbox 360's up and running again.
We apologize for the delays getting word out on this front. We build these games so you can play them and we wanted to make sure we’d explored all avenues for those affected before we delivered the hard and fast news"
