WD Passport for Mac falty? Appears empty every hour

Hi all! I have bought a new WD Passport for Mac couple of weeks ago, and it is working for an hour or so and then it appears empty. It is still mounted and visible, but no info on it. Then I try to safely remove it - not possible - it is in use. I push it to be removed or remove physically and mount it back - information reappears. And so on every hour. What the F it is? It’s already my 6th passport and none of previous worked like this.
