Q: Which cable and port did you use to connect LaCie 6big/LaCie 12big to the computer?
A: LaCie 6big/LaCie 12big is shipped with two USB-C cables, one for Thunderbolt 3 connections and one for
USB 3.1 connections. Both are clearly marked by logos, a thunderbolt and the number "3" for Thunderbolt 3
connections and the USB 3.1 Gen 2 logo with the number "10" for USB 3.1 connections. Since both cables
have USB-C cable ends, make certain to choose the correct cable for the interface you are using to connect
LaCie 6big/LaCie 12big to your computer.
Additionally, make certain to connect the Thunderbolt 3 port on LaCie 6big/LaCie 12big to a computer that
features a Thunderbolt 3 port. A Thunderbolt 3 port is a USB-C port that has a thunderbolt. Other USB-C
ports do not support Thunderbolt 3 connections. If your computer does not have a USB-C port with a
thunderbolt, use the USB 3.1 port on LaCie 6big/LaCie 12big. Please note that it is not possible to access
the storage when connecting the Thunderbolt 3 port on LaCie 6big/LaCie 12big to a USB-C port on a
computer that does not support Thunderbolt 3. While it is possible to connect LaCie 6big/LaCie 12big's USB
3.1 port to a Thunderbolt 3 port on a computer, the benefits offered by Thunderbolt 3 are lost. Such a
connection only allows for using a single array at transfer rates up to 10Gb/s rather than Thunderbolt 3's
potential of multiple arrays and transfer rates up to 40Gb/s.
If you see the storage using the USB connection but the Thunderbolt connection does not appear to work,
confirm that LaCie RAID Manager is installed on your computer. The installer for LaCie RAID Manager includes
an important driver that allows the computer to recognize the storage with Thunderbolt connections. The
installer can be downloaded at
LaCie RAID Manager
.
Problem: I want to change the RAID level.
Q: How do I change the RAID level?
A: You can manage the storage for LaCie 6big/LaCie 12big using LaCie RAID Manager. To download the
installer, go to
LaCie RAID Manager
. For instructions how to use the application, see the
LaCie RAID Manager
user manual
.
Problem: I disconnected my computer from the LaCie 6big/12big
during RAID synchroniza on or ini aliza on.
Q: Can I disconnect my computer during RAID synchronization or initialization?
A: Yes. Synchronization and initialization continue uninterrupted when the computer disconnects from LaCie
6big/LaCie 12big. Similarly, LaCie 6big/LaCie 12big can be placed into low power mode or powered off
during synchronization and initialization. Provided the same hard drives are in the enclosure, the operation
continues once the device is powered on. For more information, see
Operation
.
Problem: I have a USB-C hard drive that I want to add to the
Thunderbolt 3 daisy chain.
Q: Can I attach my USB-C hard drive to a Thunderbolt 3 daisy chain?
A: Yes. Make certain to add the USB-C hard drive to the end of a Thunderbolt 3 daisy chain since USB
devices do not include a second port to continue the chain. Please note that USB-C devices do not become
