What to do about a scratched copy of Black Ops?

Solution 1:

When installing games to a 360's hard drive it doesn't copy down the game's ID or anything. I've had a scratched copy of crackdown that I got working by installing a friend's copy of crackdown. We were then both able to play multiplayer together. If you can't get your disc replaced then just use your friends copy of Black Ops to install the game and then try to use your disc to run it.

Solution 2:

• It's worth trying the shop that sold it to you, but don't hold your breath; they may decide you caused the damage and refuse a refund.
• But if that happens, deal with Microsoft directly. One consequence of the legal notion that software and music companies sell licenses, not goods, is that they have to replace your media for a nominal fee, since the bulk of what you paid was for the license, not the media. So you should be able to send your damaged disc to Microsoft and get a replacement for fairly cheap.
