and then reconnect LaCie 2big Dock to the computer.
Q: Are there other Thunderbolt 3 or USB devices connected to the same port or hub?

Thunderbolt 3
Q: Is the device connected to a Thunderbolt 3 USB-C port on your computer or hub?
A: Connect LaCie 2big Dock to a USB-C port on your computer that supports Thunderbolt 3 devices. The
lightning bolt icon that represents Thunderbolt 3 support should appear next to the USB-C port.
Q: Does your computer or operating system support Thunderbolt 3?
A: Consult your computer and operating system documentation for Thunderbolt 3 compatibility information.
USB
Q: Is the device connected to Hi-Speed USB 2.0 on your computer or hub?
A: If your hard drive is connected to a USB 2.0 port, the slower performance is normal. LaCie 2big Dock USB
performance is significantly better when it is connected to a USB 3.1 port or a SuperSpeed USB 3.0 port.
Otherwise, LaCie 2big Dock operates at slower USB transfer rates.
