Disk unreadable but its a downloaded game

Hey all. I recently downloaded Forza Horizon from the market place. It'll load up to the main menu, ill select a mode and then during loading, the window will pop up saying disk unreadable. I have tried deleting and re-downloading, tried deleting, downloading
something else then redownloading it, and I've even checked other games on the harddrive, but still, it doesn't work. My hdd can't be busted cus other games work, blantently not a faulty disk, seems as there is no disk. What can I do to get it to work? I got
it to play with my friends and have fun racing but I can't, so I just wasted a load of money.

Can't Play Any Games other than borderlands & L4D2.

Um Its not my disks that won't read. Its my downloaded games that won't play, and any game that is installed. My downloaded games and installed games register as unreadable disk. Aren't they supposed to read off of the hard drive.

When I get to a certain point in the game it says disk unreadable even though its a downloaded game. I already tried redownloading it but it still does it.

 

Delete the game then try clearing the cache by going to system settings, highlight hdd and press the y button and select clear cache and then restart your console. After your console restarts, redownload the game and try again. You could have a corrupt file.
Hope this works for you.

 

To add to maximumextremes suggestion a bit, do everything he suggested, but before downloading your game again download a demo(s) about the same size as the game giving you trouble. Once that is finished download your game and delete the demo(s). If there
is corruption on your HDD saving your game in that same exact sector of the drive again will just cause the issue to repeat. By placing the demos there first you can avoid further trouble.

 

Hello there OcRz Cliche, are you trying to play Forza Horizon on the original console you downloaded it on?
