How To Fix PS4 CE-34878-0 Error | Easy Solutions

One of the common errors that a lot of PS4 gamers encounter on their console is the CE-34878-0 bug. If you are looking for a solution to this issue, this article might be of help. Learn what the causes are of this problem and how best to solve it below.

Causes of PS4 CE-34878-0 error

CE-34878-0 error can occur due to a number of factors. Most of the time, this error is caused by a corrupted HDD or hard drive but it can also show up randomly in some other situations. Let’s discuss each of the reasons for this problem.

Outdated or corrupted PS4 firmware.

Many PS4 users who don’t regularly update their console’s firmware get this error. Some new games tend to trigger this code if the firmware is not up-to-date. If you only play your PS4 offline and now you’re getting the error, you want to connect the console to the internet and download the software update directly.

Corrupted, damaged, or incompatible hard disc drive (HDD).

Many reported cases of this error mentioned that the hard drive has been changed or replaced prior to the problem showing up. In other cases, a corrupted hard drive can also trigger the problem. If your PS4 has a new HDD at this time, you might want to consider re-using the old HDD to see if that will fix the issue. Otherwise, you should troubleshoot the hard drive to make sure that it’s compatible with your PS4.


Network glitch.

In some rare instances, slow or intermittent network connection can cause the PS4 system to crash and show the error. You should try to see if there’s any on-going network issue on your end, or if there’s a server problem with PlayStation services.

Other hardware issues.

Aside from a faulty hard drive, other hardware malfunction may trigger the error as well. Depending on the state of your PS4, the error may be a sign of a still unknown hardware issue, or it may be the result of a total system breakdown.

Solutions to fix PS4 CE-34878-0 error

Fixing the PS4 CE-34878-0 error is usually accomplished easily by many gamers so we hope that yours will be the same. Learn what you need to do to solve this problem by following the solutions in order.

  1. Reboot the PS4.

    If the cause of your CE-34878-0 problem is minor or temporary, rebooting the console may be an easy fix.
    Reboot the console by doing it on your controller first. Alternatively, you can try pressing and holding the Power button in front to restart the system. 
    If it doesn’t respond, unplug it from the wall outlet or power strip and wait for about 1 minute before turning it back on.

  2. Install game and system updates.

    If CE-34878-0 error occurs when you’re trying to play or load a certain game only, make sure that you install the most recent update for the game.
    Getting the latest update for your games and console firmware should be automatic if your PS4 is regularly connected to the internet. Games that has an online component typically won’t allow you to run the game if you don’t update. The same is true if the system software is not updated.
    All you need to do is to install the update.
    In case you only want to use your console offline, you can consider a PS4 offline update.

  3. Disable Face Recognition feature.

    If your console is connected to a camera, try turning off Face Recognition and restart the PS4 afterwards. Some users have found this solution effective in fixing this CE-34878-0 bug.

  4. Manually change the console display settings.

    Some users have reported that manually changing the resolution to something other than the one’s that you’re using fix this problem. This may be caused by a bug with the PS4’s display capability. 
    To change your PS4’s resolution:
    -Go to Settings
    -Select Sound and Screen.
    -Select Video Output Settings.
    -Select Resolution.
    -Select your preferred resolution.
    If the problem won’t go away after changing the resolution, you can revert to your default resolution (usually 1080p).

  5. Troubleshoot the hard drive.

    We know that the original hard drive on many PS4 units are really limited given the huge installation space needed by many games. If you recently upgraded the hard drive but encountered the CE-34878-0 instead, try re-installing the original hard drive to see if the new one is the cause. 
    Once you’ve confirmed that the issue is caused by the new hard drive, make sure that you reformat it to FAT, FAT32 or exFAT standards. These are the ones supported by the PS4.
    In order for the PS4 to read the hard drive without issues, you can reformat it on your console. Make sure that you’re using the USB 3.0 cable (if you're trying to connect an external hard drive) and not the standard but slower USB cable.
    To format:
    -Go to Settings
    -Select Devices.
    -Select USB Storage Devices and select your external hard drive.
    -Select Format as Extended Storage and tap X.
    -Select Next and tap X.
    -Select Format and tap X.
    -Select Yes and tap X.
    -Select Okay and tap X.

  6. Rebuild the console’s database.

    If you’ve already formatted the hard drive using the PS4 but the CE-34878-0 error continues to show up, the next thing that you want to do is to try to rebuild the database. You can also do this even if you haven’t changed the original hard drive at all.
    -Turn the PS4 off completely. 
    -Once the console is fully off, press and hold the Power button on the PS4 front panel until you hear two beeps.
    -Release the Power button after the second beep, which should occur about seven seconds after the first beep. 
    -Connect your controller to the console using a USB cable then press the PlayStation button.
    -In the Safe Mode menu, choose Option 5 [Rebuild Database].

  7. Return firmware settings to defaults (factory reset).

    If you are using the original hard drive but the CE-34878-0 error is showing up when you play a game, or when you’re trying to load the system up, try to see if you can factory reset the console. There are two ways to perform a factory reset either via the Settings menu or through Safe Mode. 
    We suggest that you go through Safe Mode instead, just like in rebuilding the database but instead of selecting Option 5, pick Option 7 (Initialize PS4/Reinstall System Software).
