6. Troubleshooting
If you encounter issues with your diskAshur2, consider the following:
- Drive Not Recognized: Ensure the USB cable is fully inserted into both the drive and the computer's USB port. Try a different USB port or computer to rule out port issues.
- Incorrect PIN Entry: If the drive does not unlock after entering your PIN, ensure you are entering the correct 7-15 digit PIN. Multiple incorrect attempts may trigger security features that temporarily lock the device.
- Error Messages: If you receive an error message, try safely ejecting and reconnecting the drive. Consult the full user manual (pre-loaded on the drive) for specific error code explanations.
- Slow Performance: Ensure you are using a USB 3.0 or higher port for optimal transfer speeds. Older USB 2.0 ports will result in slower performance.
