Sony Addresses The PS4 Save File Corrupting Error CE-34878-0
PlayStation 4 users have been struggling with the ambiguous CE-34878-0 error message for some time. Its symptoms have apparently worsened, and Sony has offered a statement about what it is doing fix the issue.
When asked for comment about the recent re-appearance of the error message a representative from Sony told Game Informer in an e-mail, "We are aware of the cases, and we appreciate your patience while we investigate."
We encountered the error shortly after the console's launch in our attempts to play Battlefield 4 online. At the time, the error message would appear preventing us from playing the game online, but now PlayStation 4 owners are encountering damaged and corrupt save files alongside the error message. A thread on Sony's message boards, which was originally posted in December but continues to receive updates, has a large number of users claiming that save files for games are no longer working after the message appears for games like Assassin's Creed IV: Black Flag, Call of Duty: Ghosts and others.
If you are experiencing this ce-34878-0 error code, please close the application and then install the latest system software and game patch.
If the error occurs again, initialise the PS4 system after back-up of the save data and please also submit any crash reports after re-booting your console when the error occurs.
Hope that helps.
Sony's statement – though welcome compared to silence – is troubling and doesn't inspire much confidence for a speedy resolution. With issues like this it's always difficult to ascertain if it is truly widespread, or if the few who have had the poor luck to run into the problem just happen to be very vocal in their justified complaints. Hopefully Sony can figure out what is happening and resolve the issue and (fingers crossed) restore the save files of those who have lost progress.
