How do I disable drive unlocker on WD my passport?

I read this solution on the WD Community

http://community.wd.com/t5/External-Drives-for-Mac/How-do-I-Disable-Security-feature-on-my-1TB-Essential/m-p/541095#M7199

but it refers to a “set up” tab on the smartware software which does not exist.  Only tabs are Home, Backup, Retrieve, Settings and Help.  No sub tabs within, and I have updated with the latest version.  

Under settings look for the drive settings option.

Follow the steps on the following link:

On the 5th steps shows you how to change/remove the security.
