Keep your external hard drive in a clean, dry environment. Avoid exposing it to extreme temperatures, direct sunlight, or excessive moisture. Handle the drive with care to prevent physical damage.
4.2 Safe Ejection
Always safely eject the drive from your computer before disconnecting the USB cable. This prevents data corruption and ensures the longevity of your drive. On Mac, drag the drive icon to the Trash or use the Eject option in Finder. On Windows, use the 'Safely Remove Hardware and Eject Media' icon in the taskbar.
5. Troubleshooting
5.1 Drive Not Recognized
- Ensure the USB cable is securely connected to both the drive and the computer.
- Try connecting the drive to a different USB port on your computer.
- If using a USB hub, try connecting the drive directly to the computer.
