It turns out that the patch notes for this week’s PlayStation 4 Firmware 2.55 update weren’t quite correct. In addition to improving “System software stability during use of some features”, it’s also introduced a rather odd little disc reading bug.
Threads have popped up on the likes of Reddit, the PlayStation Community and NeoGAF complaining of PlayStation 4s no longer being able to read freshly inserted discs until the console is restarted, which then results in the triple beeps that signify a console crash. Indeed, we’ve been able to replicate the issue on a couple of our own PS4s since the update, and performed a before and after test today in to narrow it down to a software issue.
We’ve also been able to confirm some specific circumstances in which the bug presents itself. It only seems to present itself when waking the console from rest mode by using the disc eject button on the front of the machine. Should you do so, inserting a disc again then only causes the drive to spin up, but the PS4 doesn’t recognise the disc until restarted. The solution, then, is just to wake the console up with a controller or with the power button and reach the main PS4 menu before you eject your disc. It really is as simple as that.
While this bug is limited to quite specific circumstances, which will likely explain how it was able to sneak past Sony’s QA department, and might not even be a universal issue, just be aware that a simple restart of your console and slight change in your disc changing behaviour is all that’s needed if you do find yourself affected.
