The same as my console , my PS4 Slim didn't read disk games before 3 days ago. When I turned on my console,I can hear the dick spinning but after a short while it stopped. And the screen showed "Unrecognized disc ". I also found only one way can made my console read disk : turned on the console for about 10 minutes then restarted it.But I think the most useful way is change the disk driver.
