apple/lg 5K monitor USB-C Ports

Hello,

I am having aproblem with my LG/Apple sold 27" 5K monitor. The monitor works fine, the question I am having is with the ports on the back. I have a Lacie Thunderbolt 4TB hard drive that I tired to connect with the Apple Thunderbolt to USB-C cable. I get message saying cannot connect and to connect to Thunderbolt port. So I now have three ports on back of monitor that I cannot use for my hard drives. Has anyone else had this experience? Thanks, Bill

MacBook Pro TouchBar and Touch ID, iOS 11.1

The ports on the back of the display are USB-C but not Thunderbolt.

https://www.apple.com/shop/product/HKN62/lg-ultrafine-5k-display

"Ports: One Thunderbolt 3 (input), three USB-C (USB 3.1 gen 1, 5Gbps)"

What model Lacie drive do you have? The Thunderbolt-3 versions also have a USB-C port that will work with the ports on the back of he display (if you don't use a Thunderbolt only cable).

If it's a Thunderbolt-3 drive with two Thunderbolt-3 ports, you can connect one port to the computer and plug the display into the other port.

Thank you Malcolm. I have the older Thunderbolt 4TB Lacie Rugged Drive. I was using the Apple Thunderbolt to USB-C adapter. And it does not work. I love my drives and dont feel like replacing them at 350. a pop. It does work with USB 3.0 micro and power plugged in on drive. I just figured it should have worked with the adapter and no power.
