Copying files from My Cloud Home to external drive using usb leads to Error message

Good morning, I am getting a error when I try to copy files from my Cloud Home to a external drive! The language is Dutch, so if you have troubles to read it. What could be the problem? I use a brandnew external usb drive from Seagate (2 TB)

Hi edwunn,

I would suggest you to try and connect any other External Drive or USB memory stick to isolate the issue with the device.
