4 TB external hdd does not work with USB 3

[wijesijp]

I have recently purchased 4 TB external hard disk HD-LC4.0U3.

My OS is windows 10
Motherboard Gigabyte Z170-HD3


When I connect the device via USB 3 it does not get detected
When connect via USB 2 it works

Can you please offer some advice how to fix this?

Are other devices detected when connected to the USB 3 port?

[wijesijp]

Yes

I even have a buffalo 3TB external hdd. It works fine with this port.

That's odd. I don't suppose you have a different system to try to connect it to?

[wijesijp]

I did connect to office computer.
But I am not sure whether I connect using USB 2 or 3

What can I do to figure out what is happening?

Can you give me any suggestions to get this fixed?

I assume you have tested it with a second USB 3 cable? if so and then issue is the same on multiple PCs then RMA the unit.

I would agree. If the unit won't connect via USB 3 on multiple computers, RMA the device.
