6. Troubleshooting
If you encounter issues with your DataTraveler microDuo 3C, try the following steps:
- Drive Not Detected:
- Ensure the drive is fully inserted into the USB port.
- Try a different USB port on your device.
- Test the drive on another computer or compatible device to rule out a device-specific issue.
- Restart your computer or device.
- Slow Transfer Speeds:
- Ensure you are using a USB 3.0/3.1/3.2 compatible port for optimal performance. Connecting to a USB 2.0 port will result in slower speeds.
- Check if other applications or processes are heavily utilizing system resources.
- Ensure the drive is not excessively fragmented (though less common with flash drives, it can occur).
- Cannot Write Files:
- Check if the drive is full.
- Verify that the files you are trying to write are not read-only.
- If the drive is formatted as FAT32, individual file sizes are limited to 4GB. Consider reformatting to exFAT if you need to store larger files.
