i put my watch dogs disc into my PS4 and went to play it. i got about 5 minutes in to the game when weird noises started coming from the disc tray and it ejected my disc saying it was unreadable. i thought it must be dirty and cleaned it and put it back in. this time it got to the title screen and it made weird noises coming from the disc tray, but this time it didnt eject when i went to eject it, it just made weird noises and on the 3rd try it came out. i tried putting other games discs into the ps4 an they work perfectly fine. And the watchdogs disc itself is basically spotless with no outright problems that i can see. does anyone know whats wrong?
