How to fix corrupted data on ps4

Basic repair method: Quickly solve common problems

1. Restart and Safe Mode

Operation steps: Press and hold the power button for 7 seconds to enter safe mode, select “Restart PS4” or “Rebuild Database” (option 5).

Applicable scenarios: Data read exceptions caused by temporary system failures or database index errors.

Principle: Rebuilding the database will scan the hard drive and reorganize the data index, fixing file fragmentation issues caused by power outages or abnormal shutdowns, but will not delete games or saves.

2. Update system software

Operation steps: Go to “Settings”>”System Software Update”, connect to the network to automatically download the latest firmware.

Applicable scenario: Data corruption caused by system vulnerabilities (such as error code NP-32062-3).

Case: The 9.60 version update released by Sony in June 2025 fixed archive encryption vulnerabilities, and 80% of similar issues were resolved after the update.

3. Reinstall the game/application

Operation steps: Long press the game icon on the main interface and select “Delete”, then download again from the PS Store.

Key point: Before deleting, it is necessary to confirm whether the game data is stored in the cloud or an external hard drive to avoid accidentally deleting saved files.

2、 Data recovery technology: deep repair for physical/logical damage

1. Logical damage recovery (file system error)

Tool recommendation:

Panda Assistant: Supports the NFT/FAT32/exFAT file system, which can recover data loss caused by accidental deletion, formatting, or virus attacks.

Operation process:

Connect the PS4 hard drive to the computer via a SATA to USB cable.

Run the recovery software and select ‘PS4 System Partition’ for a full disk scan.

Preview recovered files, filter key formats such as. sav (save) and. psarc (game resource pack).

Save to an external hard drive to avoid overwriting existing data.

2. Physical damage repair (hard disk bad lane/motor failure)

Professional equipment requirements:

PC-3000 Portable: Can read damaged hard drive firmware area and repair LBA mapping table.

MRT Pro Ultra: Supports electromagnetic head calibration for SHDD (hybrid hard drives).

Operational risk:

Cleanroom environment requirements: The hard drive must have a Class 100 cleanliness level when opening, otherwise dust particles may scratch the disc.

Data coverage probability: Each power on attempt to restore will reduce the data survival rate in the bad lane area.

3. Cloud archiving and backup restoration

PS Plus Cloud Archive:

Synchronization condition: Keep automatic upload enabled (Settings>Application Save Data Management>Automatic Upload).

Recovery limit: The maximum size of a single archive file is 8GB, and if it exceeds this limit, it needs to be compressed and uploaded in separate volumes.

External hard drive backup:

Format requirement: exFAT or FAT32 file system must be used (NTFS format requires PS4 system support of 9.00 or above).

Restoration steps:

Connect the backup hard drive to PS4

Go to Settings>System>Backup/Restore>Restore PS4.

Select the backup date and confirm to overwrite the current data (this operation is irreversible).

3、 Special scenario handling: solutions for specific error codes

1. Error code CE-34878-0 (application crashes)

Root cause: Game cache conflict or system memory leak.

Solution:

Go to Settings>Storage>System Storage>Applications.

Select the problem game and press the ‘Options’ button to delete cached data.

After restarting, download the game patch again (the version number must be consistent with the server).

2. Error code NP-36006-5 (network archive synchronization failed)

Troubleshooting steps:

Check the PSN server status (status. playstation. com).

Change DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

Turn off the router’s UPnP function and switch to port forwarding (TCP/UDP 80.443. 3478-3480).

3. Archive damage repair (. sav file cannot be read)

Manual repair tool:

Save Wizard for PS4: editable archive checksum to fix CRC errors caused by abnormal shutdown.

Bruteforce Saved Data: Recovers encrypted archive keys through brute force cracking (requires original PS4 host activation).

Operation warning: Modifying save files may violate the game’s terms of use and pose a risk of account suspension.

4、 Preventive maintenance: reduce the probability of data corruption

1. Hard disk health management

SMART monitoring: Use CrystalDiskInfo to view parameters such as “reallocated sectors” and “current number of sectors to be mapped”. When yellow alerts appear for items “05” and “C5”, immediately backup the data.

Heat dissipation optimization:

Clean the dust net: Clean the dust at the inlet of the main engine with compressed air every 3 months.

Hard disk temperature monitoring: Install HWMonitor to ensure that the operating temperature is ≤ 45 ℃.

2. Power protection scheme

UPS uninterruptible power supply:

Recommended model: APC BK650M2 (supports 30 minute battery life, voltage fluctuation protection).

Wiring method: Connect the PS4 power cord directly, avoiding switching through a power strip.

Automatic shutdown settings:

Go to “Settings”>”Power saving settings”>”Set features in standby mode”>”Turn off automatic downloads”.

3. Archive backup strategy

Rule 3-2-1:

3 copies: original archive, cloud archive, external hard drive backup.

Two media: SSD+Blu ray Disc (M-DISC Millennium Disc).

1 remote location: Store encrypted backups in a family or friend’s home or bank safe.

5、 Ultimate solution: Dealing with data that cannot be recovered

1. Official maintenance services

Sony Authorized Service Center:

Service scope: Mainboard level maintenance, hard drive replacement (purchase certificate required).

Data recovery success rate: Only about 30% of physically damaged hard drives can extract partial data.

Third party repair service provider:

Risk Warning: Unauthorized repairs may result in loss of warranty eligibility and pose a risk of privacy breaches.

2. Game progress compensation

Contact the publisher:

Some manufacturers (such as EA and Ubisoft) provide “progress reset” services, which require proof of purchase and account information.

Example: In 2024. Final Fantasy VII: Remake lost player progress due to a cloud save vulnerability, and SE issued a “Master Sword” redemption code to affected users.
