Reply:If it said "Disc is unreadable" then its most likely isolated to the Halo 3 disc. My dear friend, the X360 is notorious for scratching discs (see source) and unfortunately, Microsoft does not have any way of rectifying this on already sold consoles.





However, if you've started seeing the "To play this disc, put it in an XBox 360 console" message, chances are your disc drive is dying. One fine day, it will completely stop working and keep throwing the same message for every damn disc that you have. If you are covered by the regular 1 year warranty period, you can get your unit replaced (takes anywhere from 2 weeks to a month's time for the replacement to happen, depending on where you are).
Reply:even the smallest scratches on an xbox 360 disc can affect the way the game plays...there is a solution to get these scratches removed, try a discstation.com.au, they're running a free xbox 360 disc scratch repair offer at the mo,
