Xbox 360 unreadable disc

Some video stores offer to re surface discs or you could rent/borrow a copy and download game to harddrive this usually will allow play with an unreadable disc

your game is not right downloaded because probably is a piece of the game but i think is not the full game so try to download it somewhere other website and try it again.I hope it helps

find out which dvd drive you have, hitachi, samsung, phillips, etc...then buy a 20 dollar replacement same brand, switch the little green board from yours to the new one, new drive no errors...hope it helps...

Could you tell us more? Are these burned games?

Some game are compatible with the new xbox 360. They are called backwards compatible and you do need to flash upgrade the OS on the new xbox 360 system.

You need to go to the xbox website and go to support and download the flash update then burn it to disk and put it on the xbox to update the software. Again not all old games are compatible with the new xbox system. If your buying used games like I do make sure it says bc next to the title before buying them.
Here is the link to the upgrade

I had the same problem but i sent it in. They said it was the eye reader error. Or the thing that reads the disc. Try buying a brand new game and try playing it. Alot of times when i have disc read errors i put the disc in where the xbox 360 part at the top goes in facing the xbox. Try that to see if it helps.

Try And clean it breath on itand wipe with your tshirt

use PLEDGE spray can on it to fix the scratches

i reccomend if ur a live member download some multiplayer demos (i personnaly play bf badcompany) sicne they dont work and clean ur disc(s) with a cloth if that doesnt work it might be scrachted so i reccomend goin to game stop and trade it for a better game or pay to get it fixed

my xbox360 live service is dont work
