Thunderbolt 3/USB
Q: Are both ends of the cable firmly attached?
A: Review troubleshooting tips for cable connections below:
Check both ends of the cable and make sure they are fully seated in their respective ports.
Try safely ejecting LaCie 6big/LaCie 12big from your computer and then disconnect the cable. Wait 10
seconds and then reconnect LaCie 6big/LaCie 12big to the computer.
Q: Are there other Thunderbolt 3 or USB devices connected to the same port or hub?
A: Disconnect other devices and see if the drive's performance improves.
Thunderbolt 3
Q: Is the device connected to a Thunderbolt 3 USB-C port on your computer or hub?
A: Connect LaCie 6big/LaCie 12big 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 6big/LaCie
12big USB performance is significantly better when it is connected to a USB 3.1 port or a SuperSpeed USB
3.0 port. Otherwise, LaCie 6big/LaCie 12big operates at slower USB transfer rates.
Problem: I connected LaCie 6big/LaCie 12big to my computer but it
does not power on and I cannot see the device in LaCie RAID
Manager.
