6. Troubleshooting
6.1 SSD Not Detected
- Ensure the USB cable is securely connected to both the SSD and your device.
- Try connecting the SSD to a different USB port on your device.
- Test with a different USB cable if available.
- Verify that your device's operating system is up to date.

6.2 Slow Transfer Speeds
- Ensure you are connected to a USB 3.1 Gen 2 (or at least USB 3.0/3.1 Gen 1) port on your device. Connecting to a USB 2.0 port will result in significantly lower speeds.
- Check if other applications or processes are heavily utilizing your system's resources or disk I/O.
- The actual speed may vary due to host hardware, software, usage, and storage capacity.
6.3 Formatting Issues
- If you encounter issues formatting the drive, ensure you have administrative privileges on your computer.
- Refer to your operating system's disk management tools for advanced formatting options.
- If a mobile device requires FAT32, ensure you format the drive to FAT32 using a computer before connecting it to the mobile device.
