How To Change Password in Passport Ext HD?

I set a password when I first set up My Passport USB external HD.  I now wish to change the password but can’t find how to start/enter the SmartWare program to do that.  The manual says to go to the Settings tab and the Drive Settings screen but how to I launch the program to get there?  I have looked in the different files in the WD Smartware folder using Windows Explorer but can’t seem to find a way of starting the correct program to get into the Drive Settings area.

Thanks for the help.

Welcome to the WD Community MacKenrick. You can use Smartware or WD Security for Windows to add/change or remove the password protection. Check the links below for more information.
