Driver for Wd My book

Hello,
I have a WD My Book 4 TB which I accidently reformated after it did not show in the File manager. It still does not show but also show that one driver is missing. As I have reformat it can I use it as an external harddisk (and not as a backup unit) and what driver do I need for it to work as an ordinary external unit?
I use the latest version of Windows 10 on my computers.
