Setting up a 1TB Passport Ultra as a backup when used previously on another system

I just had to download a new install of Windows 10 64bit on my computer. I have a 1TB WD Passport that I used as a backup before. How do I format the drive so I can re-use it as a backup?


Please take a look at this links. Here you will find instructions about how to format the drive.

I figured it out.
Thank you!
