We have heard some reports earlier today that some Xbox 360 users have been receiving emails from Microsoft, regarding an issue where they were unable to play any Xbox 360 games. It should be worth noting that this is unrelated to the upcoming release that has been in beta and is not tied to one “version†of Xbox 360.
If you think you have been affected, make sure to check your emails, and/or feel free to reach out to Xbox Support. More information from Microsoft is quoted below.
Following a recent update to our system software, we have become aware of an issue that is preventing a very small number of Xbox 360 owners from playing retail game discs. This issue manifests itself as a unique “disc unreadable†or “disc unsupported†error on the screen and is unrelated to our recent public beta. We are also able to detect this issue over Xbox LIVE and are proactively reaching out to customers that may be impacted to replace their console. Any Xbox 360 owners receiving this error are encouraged to contact us at www.xbox.com/support/contact so we can verify if the console has been impacted.
This disc read error message is tied to a change in the disc reading algorithms in a recent software update and is not specific to older or newer versions of Xbox 360.
If you have this error, we recommend you reach out immediately, as you may be able to get a new console, and possibly a year of Xbox LIVE for free (according to what some other users are reporting).
