It keeps saying "game error disc is unreadable" even tho I'm playing BO2 which is downloaded

Edit* the error says the disc is unreadable. Even if there is no game in and it's the downloaded version

I erased wot and tried to rredownloaded it and when I try to play it. I'm going through the in game downloading . As it downloading the game error pops up and says this disc is unreadable and I'm like what disc. There's no disc

Same issue, I get the "disc is unreadable" error, but even with downloaded games that have no disc. The error appears after 3 loading screens with all of my games.

This is a game downloaded from Xbox Marketplace, not a disc.

That's why I'm curious about the "Disc is Unreadable" error, when there isn't a disc involved.

I would try two different things. First since the purchases you have made are stored, I would delete the game and reload it. Second, I would shutdown the xbox, pull out the HDD and clean the contacts with a cotton swab and rubbing alcohol. Third, I would
copy my profile onto a usb stick and format my HDD. It sounds like the HDD is corrupted.
