WD easystore, not so easy

My new WD easy store has been anything but easy to install and use for my Mac. I’m a bit of a novice so when I bought this product I was told just plug it into your computer and your set. But I’m not set at all, can I get a little tip to get started?
Thanks

probably helps to explain in detail what the problem is :confused:
