Chosen Solution

Hi there, Recently, my PS4 slim started making a knocking noise, seemingly from the disc drive, as it only makes the noise while a disc is inserted. Apart from this noise, it operates normally (reading and ejecting discs is fine, etc). I was wondering if anyone might know what the cause might be, as well as if there is an inexpensive fix to the problem. Thanks in advance.

Just replace the drive. It will only get worse. PlayStation 4 Slim Disk Drive Replacement
