Moving My Passport Ultra to a new PC

I bought a new PC. I would like to use My Passport Ultra to back up that PC. How do I reset or reformat My Passport so that all data and options used for my old PC are removed? I would like to start with a fresh device.

You need WD Utilities from the Downloads Tab. That will Erase your drive and you can start over on the new PC. Read the Help on the Utilities screen.
