Use passport with non WD drive

I purchased, and installed a new 1TB WD passport so I could have two backups; with one off site. My current external backup in on a 1TB Seagate external drive. I would like to run the WD backup program on it as well. 

How can I configure the Seagate so both drives are using the same, WD backup configuration?

That’s not possible…Smartware won’t work on the seagate drive…
