Troubleshooting
If you encounter issues with your LaCie 2big Dock RAID, consider the following common troubleshooting tips:
- Drive Not Recognized: Ensure all cables (power and data) are securely connected. Try connecting to a different port on your computer or using a different cable. Verify that the LaCie Toolkit software is installed and updated.
- Fan Noise/Temperature: The cooling fan is temperature-controlled and may not activate immediately upon power-on. It will engage as the internal temperature rises during operation. This is normal behavior.
- Bright Blue LED: The front blue LED indicates power and activity. If its brightness is disruptive, the LaCie Toolkit application may offer settings to adjust LED intensity.
- Slow Performance: Ensure your computer's drivers for Thunderbolt/USB are up to date. Check the RAID configuration in LaCie RAID Manager; RAID 0 offers higher performance but no redundancy, while RAID 1 offers redundancy at the cost of some speed.
