How to add password to Passport Drive when Smartware won't recognize it

I have two passport drives. One won’t open without the WD Smartware and password. The password pages opens automatically when I plug in the drive. Good.

I have a second drive that I was sharing initially but now I want to password protect. The drive icon pops up in the desktop immediately. I want to add password protection but the WD Smartware doesn’t recognize the drive for me to go in and change settings. 

How do I get the Smartware to recognize the second drive and automatically open when I plug it in? Thanks,

Can you post both drive model number?
