5. Troubleshooting
- Drive Not Recognized:
- Ensure the drive is fully inserted into the USB port.
- Try a different USB port on your device.
- Test the drive on another computer to rule out a device-specific issue.
- Check your device's 'Disk Management' (Windows) or 'Disk Utility' (macOS) to see if the drive is detected but not assigned a drive letter or mounted.
- Slow Transfer Speeds:
- Ensure you are using a USB 3.0 or USB 3.1 compatible port for optimal speeds. USB 2.0 ports will operate at slower speeds.
- Transferring many small files can be slower than transferring a few large files.
- Close other applications that might be using system resources or accessing the drive.
- Data Corruption:
- Always safely eject the drive before removing it.
- Avoid disconnecting the drive during active file transfers.
- If data corruption occurs, you may need to reformat the drive (this will erase all data).
