Summary for me after reading and researching is: Halo Reach 'disc unreadable' happens while almost all other games discs work (Halo 3, ODST etc).The Xbox will provide 'disc unreadable' error REGARDLESS of the condition of the disc surface. XboX Support will NOT tell you why, they will only walk you through some fixes which WILL NOT resolve problem. In the end they will offer to repair it, for those with warranty for free (?), for those without 100-120$. It feels like a corporate strategy to force die hard gamers to RE-BUY new consoles as Xbox moves into its twilight years. This way peeps who want to play the last generation of games are forced to purchase new consoles, letting M$ milk enthusiastic gamers for profit. Will the NEW HALO CE have the same problem? Probably. Things I have tried that did not work: -Removing Hard Drive and trying to playing game. -Disconnecting from Wireless/wired network connection and trying to play game. -Clearing systems cache, and doing the 'real' clearing of systems cache (the LB, RB, X, -blam!-) and trying to play game. -Jimmy's stupid magnetizing trick. -Installing games on HDD and trying to play game. I have not talked to Bungie about this problem. I have talked to Microsoft about this problem, and they blame this problem on your console which is illogical because of two reasons. First, if something was wrong with the consoles all games should be affected (i.e. laser prob, disc tray prob etc..). Second, Halo Reach DID WORK on my console when I first bought it. It was not until some months later this year, after Xbox sent out new updates, that the 'disc unreadable' problem began. As such, it seems the new updates have had the effect of invalidating older consoles from playing Halo Reach. That this happens, and with Xbox's flagship series most recent game is absolutely disrespectful to Halo fans. For all these people out there who just want to play the game I feel for you. Halo, for many, is the only redeeming aspect of 360, and to be UNABLE to play ONLY this ONE GAME is a slap in the face to xbox supporters. This will certainly be the end of my ten year relationship both with Bungie and M$. [Edited on 10.20.2011 2:42 PM PDT]
