There are a few reasons why your PlayStation 4 might be spitting out discs. One is that the disc drive is not working properly. Another is that the PlayStation 4 has a problem with its software installation process. If you have any of these problems, you can try to fix them by going to your PlayStation 4’s “Settings” menu and selecting “System Settings.” There, you can change things like the “PlayStation4 Disc Drive” setting to “Not Supported.”
