If you’re ever going to lose a disc in your PlayStation 4, there are a few things you can do to help. First, make sure that your PS4 is properly plugged in and that the power is off. Second, try taking the disc out of its casing by gently pushing it out from the back. Finally, if you’re using a digital code to unlock content on your PlayStation 4, make sure that it’s working correctly - if not, try again later with another code.
