If your PS4 prompts you to format the drive, proceed with the formatting process. Note: Formatting will erase all data on the drive. Ensure no critical data is present before proceeding.
2. Operating Instructions
2.1 Powering On and Off
To power on the device, ensure the power adapter is connected and flip the power switch on the rear of the unit to the "ON" position. The blue LED indicator will illuminate. To power off, flip the switch to the "OFF" position. Always ensure your PlayStation 4 is properly shut down or the external drive is safely ejected via the PS4 system menu before disconnecting power or the USB cable to prevent data corruption.
2.2 Storing Games and Data
Once configured as extended storage, your PlayStation 4 will automatically install new games and applications to the Avolusion HDDGear Pro X. You can also move existing games and applications from your PS4's internal storage to the external drive via the PS4's system settings (Settings > Storage > System Storage > Applications > Options > Move to Extended Storage).
2.3 Device Placement
The Avolusion HDDGear Pro X can be placed horizontally or vertically to suit your setup. Ensure adequate ventilation around the device to prevent overheating, especially during prolonged use.

3. Maintenance
3.1 Cleaning
To maintain optimal performance, keep the external hard drive clean. Use a soft, dry cloth to wipe the exterior. Avoid using liquid cleaners or abrasive materials, as these can damage the device. Ensure ventilation openings are free from dust buildup.
3.2 Data Management
Regularly review the contents of your hard drive. Delete unused games or applications to free up space. While the drive is designed for reliability, it is always recommended to back up critical game saves or data to cloud storage or another device if possible.
4. Troubleshooting
4.1 Drive Not Recognized by PS4
- Check Connections: Ensure the USB cable is securely connected to both the hard drive and the PS4. Verify the power adapter is firmly plugged into the drive and a working power outlet.
- Power Cycle: Turn off the hard drive and your PS4. Disconnect all cables, wait a few seconds, then reconnect and power on the devices in sequence (hard drive first, then PS4).
- Try Different USB Port: Connect the USB cable to a different USB port on your PS4.
- PS4 System Update: Ensure your PS4 system software is up to date.
4.2 Slow Performance or Game Loading
- USB 3.0 Connection: Ensure the drive is connected to a USB 3.0 port on your PS4 for optimal speed.
- Avoid Overheating: Ensure the drive has adequate ventilation and is not placed in an enclosed space.
- Rebuild Database: On your PS4, try rebuilding the database (this can sometimes improve system performance).
4.3 Power Indicator Light Not On
- Check Power Adapter: Verify the power adapter is correctly connected to both the drive and a functional power outlet.
- Power Switch: Ensure the power switch on the rear of the drive is in the "ON" position.
