How to avoid a wd passport essential drive from appearing in Smartware software backup

Hello,

 Thank you for your reply. It is a sad thing to hear that the software does not permit to blind one of the units from being seen as a target for the software backup. Perhaps it should be considered as an improvement for new software releases.

 Still, is there a way to be able to get rid of the Smartware software backup but being able to password protect the WD 500Gb. passport essential, being this way able to backup this drive in the bigger My Book Essential?

  Thanks a lot in advance for any suggestion.
