Troubleshooting
- Drive Not Detected:
- Ensure the drive is fully inserted into the USB port.
- Try a different USB port on your device.
- Restart your computer or mobile device.
- For mobile devices, check if your device supports USB OTG (On-The-Go) functionality.
- Slow Transfer Speeds:
- Ensure you are using a USB 3.0/3.1/3.2 compatible port on your computer for optimal speeds. Connecting to a USB 2.0 port will result in slower transfers.
- Large numbers of small files can transfer slower than a single large file of the same total size.
- Close other applications that might be using system resources.
- Data Corruption:
- Always use the 'Safely Remove Hardware' option on computers before unplugging the drive.
- Avoid unplugging the drive during active file transfers.
- Insufficient Storage Space:
- Verify the actual free space on the drive. Note that a small portion of the drive's capacity is used for system files and formatting, resulting in slightly less usable space than advertised.
- Delete unnecessary files from the drive or transfer them to another storage location.
