If you have a PlayStation 4 and it keeps giving an “Unrecognized Disc” error, this is a common problem with several causes and fixes.

This is a known error with the PS4 that many users report having at some point in the system’s life.

PS4 Unrecognized Disc Mechanical vs. Software Fixes

When a disc is unrecognized, two main things can cause the problem, mechanical and software.

You have likely already tried to clean the disc but be sure to test the PS4 with a know good disc to see if it works.

If a known good disc works, it is likely a software problem with the main fixes below.

If there is a lot of noise inside the case when it is trying to read the disc, it can also be the rollers which can cause problems.

When there is a mechanical problem, many users have had good success placing the unit on its side.

The main thing is to verify if it is a software problem or mechanical problem as these are two very different fixes.
