What's wrong with an Ubuntu 16.04 system when plugging in an external screw?

Question

ubuntu

I have an external screw. When connected to a computer with Ubuntu 14.04 everything is fine. When connected to a computer with Ubuntu 16.04, it barely works (a few minutes before mounting, slow operations with files and folders). Formatted. The same with empty. What to do?

Answer 1
