6. Troubleshooting

If you encounter issues with your FANTEC QB-35U31, please refer to the following common problems and solutions:

• Enclosure not recognized by computer:
  • Ensure the power adapter is securely connected and the enclosure is powered on.
  • Verify the USB 3.1 cable is correctly connected to both the enclosure and your computer. Try a different USB port or a different USB 3.1 cable, as some cables may be incompatible or faulty.
  • Check your computer's Device Manager (Windows) or System Information (macOS) to see if the device is listed. Update your USB 3.1 drivers if necessary.
  • Test the enclosure with another computer if possible.
• Hard drives not detected:
  • Ensure the hard drives are properly seated in their bays and the fixing handles are securely attached.
  • Check Disk Management (Windows) or Disk Utility (macOS) to see if the drives are visible but uninitialized or unformatted. You may need to initialize and format new drives.
  • Test each hard drive individually in another enclosure or directly connected to a computer to rule out drive failure.
• Slow data transfer speeds:
  • Ensure you are connected to a USB 3.1 (Gen 2) port on your computer. Connecting to a USB 2.0 or USB 3.0 port will result in lower speeds.
  • Verify your USB 3.1 drivers are up-to-date.
  • The actual transfer speed is also limited by the speed of the installed hard drives.
• Excessive noise:
  • Check the fan speed setting and adjust it to a lower level if desired.
  • Ensure the enclosure is placed on a stable surface to minimize vibrations.
  • Hard drive noise can vary; consider the noise levels of your installed drives.
