Troubleshooting
- Drive Not Recognized:
- Try inserting the drive into a different USB port or another computer. Ensure the USB port is functioning correctly. Check your computer's Device Manager (Windows) or System Information (macOS) to see if the drive is listed.
- Slow Transfer Speeds:
- Ensure you are using a USB 3.0 or 3.2 port for optimal speeds. USB 2.0 ports will result in slower transfers. Large numbers of small files can also transfer slower than a single large file of the same total size.
- Data Corruption:
- Always use the 'Safely Remove Hardware' or 'Eject' function before disconnecting the drive. If data corruption occurs, consider using the included data recovery software.
