Reports have been floating around the net for a few weeks now that numerous PS4 users have seen the CE-34878-0 error code appear and corrupt their save files beyond repair, often wasting up to 40 hours of work for the likes of Assassin's Creed IV.
However, new evidence suggests the system error isn't just focussed on our game save files and is spreading throughout the PS4's other features.
I've experienced this firsthand -thankfully not in save files so far- with consistent crashes when browsing my captured screenshots or videos taken with the new Share button. For example, when previewing numerous screenshots in full size I'm only able to swap between one or two before the console freezes for a few seconds and the dreaded CE-34878-0 error message appears with the option to report the error to Sony.
This now happens every time when browsing files in full-screen mode. This hasn't always been the case though, as I've been snapping away with the Share button since launch, but it's only in the last week or two I've encountered the error.
The fact that most of the CE-34878-0 reports have been based around corrupted save files -and now captures- is particularly concerning as it points towards the possibility that problems are spreading throughout Sony's hardware, the hard-drive in particular.
On the other hand, our consoles are still under warrantee for a while and Sony has acknowledged the problem regarding save files, so fingers crossed a fix is on the way rather than a recall. Just to be on the safe side though, we heartily recommend backing up your game saves on PS Plus AND on a USB memory stick.
