Fix 4: Re-Install the Original Hard Drive

After upgrading the internal hard drive, certain compatibility or hardware issues can cause the CE-34878-0 error. Reinstalling the original drive is a reliable way to rule out drive-related problems.

Fix 5: Factory Reset Your PS4

When all other solutions fail, a factory reset is the final option. This process resolves most performance-related issues but will erase all data on the console, so backing up your files first is essential.

Move 1: Prepare an External Storage Device

You will need an external USB drive formatted as FAT32 or exFAT with sufficient capacity—ideally at least twice the size of your PS4’s internal storage. If your drive uses the NTFS file system, reformat it using a reliable tool such as MiniTool Partition Wizard.

Follow these steps to format the drive:

1. Connect the USB drive to your computer and launch MiniTool Partition Wizard.
2. Select the partition on the external drive and click Format Partition.
3. Choose FAT32 or exFAT from the File System drop-down menu and click OK.
4. Click Apply to complete the formatting.

Move 2: Back Up Your PS4 Data

Once the drive is ready, back up your data:

1. Connect the formatted USB drive to your PS4.
2. Go to Settings > System > Back Up and Restore > Back Up PS4.
3. Select the data you want to back up and choose Next.
4. Name your backup and press the X button to begin the process.

After the backup finishes, safely remove the USB drive.

Move 3: Initialize PS4

With your data safely backed up, perform a full initialization:

Go to Settings > Initialization > Initialize PS4 and select Full initialization. Follow the on-screen instructions to complete the process.

After initialization, return to Settings > System > Back Up and Restore > Restore PS4 to reload your saved data. Reinstall your games and applications, and the CE-34878-0 error should be permanently resolved.
