Diagnose Error (CE-34878-0)

It is necessary to diagnose PS4 Error Code (CE-34878-0) by watching the behavior of your console before attempting to fix it. Be aware of when it first happens and then attempt to fix it.

When PS4 Error (CE-34878-0) is encountered during the initialization or formatting process of PS4, it indicates that the internal hard drive may need to be formatted.

Games and movies are often the only ones that cause this problem. However, it usually does not happen when running applications. It would seem that the PS4’s graphics card is suffering from a problem. You can sometimes solve the problem by connecting it to another monitor.

If this error occurs only with games installed on an external hard drive, that means the drive is defective. You need to FULL format, not a quick one, because of the bad sectors. By completely formatting the drive, bad sectors will be removed/fixed and the drive’s performance will be restored.

Playing online and getting the error (CE-34878-0) is most likely caused by an interrupted internet connection.

The error can also be caused by a sudden power surge or a hardware failure. The error is usually temporary and won’t occur again.

Regardless of the reason, you need to go through this guide and find a proper solution for Error Code (CE-34878-0) that fits your needs.

Restart your PS4

You should restart the PS4 as soon as possible when you receive error code CE-34878-0. Make sure that this has resolved the issue afterward.

You may need to unplug the PS4’s power cable and fully turn off the system if a restart didn’t fix the Error (CE-34878-0). You can successfully perform this operation by following the simple steps listed below.

1. Turn off the PS4.

2. Remove the power plug from the PS4.

3. Wait between 30 and 60 seconds.

4. Reconnect the power source.

5. Turn on the PS4 and let it start.

There are many benefits to turning off the PS4 when it comes to its overall performance.

If the error does not appear again, launch that game or app that caused the error once the console boots up.

The next time Error (CE-34878-0) occurs, but it takes longer than in the past, you’re on the right track and close to figuring out why it occurs. To restart your PS4, you must turn it off again, and then wait 5-10 minutes before turning it on again.

Check the PS4 carefully after starting it up again. Is Error (CE-34878-0) appearing faster than before, or is there no change? You might have an overheating issue with PS4 if it takes longer than expected.

Update the PS4 system software

Many performance issues on PS4 can be resolved by updating system software. As a result, you should always update the system software on your console to the latest version.

You can begin the process by following these steps:

1. To access settings, select the home screen of your PlayStation.

2. From the System Software Update menu, choose the updated version.

3. Updates for your PS4’s system software are checked for and installed as necessary. Just let it run.

4. Restart the PS4 after the installation has been completed and check which specific game/app caused the error.

Try another solution if the solution above did not fix the error and the annoying message still appears.

Update your game/app


Occasionally, the failure comes from a deficient or incorrectly coded file within the game/app. This is why manufacturers continually release patches to fix these issues in their games and apps.

Here are the steps you need to take:

1. Open the Home screen on your PlayStation.

2. Select the game that is affected.

3. Click the Options button on the controller.

4. Check for updates and install any available game updates for the affected game by selecting Check for updates.

Upon completion of the process, try launching the Win/App and see if the problem has been resolved yet.

Connect a PS Camera to the system, then remove it, reboot the system, and disable Enable Face Recognition.

  • On the home screen of your PlayStation 4, select Settings.
  • Click on the user icon.
  • Then select Login Settings.
  • Disable Face Recognition

Disable all mods

According to some gamers, disabling mods that were recently added fixed this problem. It is worth experimenting with this solution, even though it might not work for everyone.

Change the PS4’s display settings

Many users have reported fixing this problem by switching from Automatic to 720p during the video output process. However, others may also experience the same issue. If you want, try each one and see which one suits you best.

If you choose a different video resolution from the default, the PlayStation 4 will automatically switch to that setting.

  1. Go to Settings > Sound and Screen.
  2. Select Video Output Settings > Resolution.
  3. Select your default resolution:
  • 480p
  • 720p
  • 1080i
  • 1080p (the default resolution for most PS4 games)

That’s it.

Check the Hard Drive

If you have recently changed the stock hard drive of a PS4 and are experiencing the Error (CE-34878-0), then try installing the original hard drive and see if this fixes the error. The original/stock hard drive of the PS4 is often the source of this error.

In the meantime, or if you have already upgraded the PS4 internal hard drive, but are experiencing Error (CE-34878-0), the hard drive may not be functioning properly and needs service.

Almost every savvy person has experienced a hard drive failure at some point in their career. The hard drive malfunctions for several reasons, including bad sectors preventing the drive’s operation. There’s also a good chance that if the HDD isn’t clicking or grinding, the issue can be solved.

NOTE: There might be no problem with the PS4 internal hard drive, but there is a sort of power shortage that prevents the hard drive from running properly. Using an SSD instead of your PS4 HDD is the most cost-effective way to fix this issue since SSDs use less power and are more resistant to power surges.

Rebuild the PS4 database

It is possible to fix this error by rebuilding the PS4 database, which sometimes resolves this issue. The process is very simple, but it might take an hour or so.

1. Shut down your PlayStation 4 completely (i.e. not in sleep mode).

2. Keep holding the power button until the PS4 turns back on. Then release it after you hear two beeps: the first upon pressing and the second shortly thereafter. Safe Mode will be activated.

3. Press the PS button on the DualShock 4 controller while connected via a USB cable.

4. Use the USB cable that came with the controller if the PS4 isn’t recognizing it. You could also have attached a ‘power only’ USB cable.

Factory Reset your PS4

For the PS4 to be reset to factory settings, you need to go through the PS4 initialization process. You’ll be able to resolve a lot of issues related to the PS4’s performance by performing PS4 initialization. To use the PS4, users must know the correct procedure.

The console’s hard drive will be completely erased when a factory reset is performed, and its system software may also be removed. This is your last resort if a software bug stops your PlayStation 4 dead in its tracks, especially while booting up or when you want to make sure your data is no longer stored on the console.

If you intend to keep any data, like images and videos, you should back it up to an external device or the cloud. PlayStation Plus accounts are necessary for backing up data in the cloud.

In addition to the dashboard, you can also reset your PS4 by going to Safe Mode if the console isn’t responding. To fix the PS4 error (CE-34878-0), you must carry out a full initialization.

During initialization, your PS system should not be turned off. The system may be damaged.

  1. Go to PS4 Settings > Initialization > Initialize PS4.
  2. Select Full.

3. Follow the instructions.

4. Reinstall all your games and applications after restoring your backup data.

5. Make sure that they work.

PS4 CMOS memory must be cleared

If you’ve already tried everything above and it hasn’t worked, then you’ve reached this point. You will need a bit of knowledge to carry out this suggestion. Fixing Error [CE-34878-0] on the PS4 system should be your last resort if you want to do it yourself. Now that you’ve cleared the CMOS memory on the PS4 the problem should be fixed. Since the PS4 CMOS battery needs to be removed carefully, this could be a long and difficult process.

Do not attempt to do something if you can’t. Instead, contact a technician who knows what they’re doing.
