Ext WD Drive not visable to Smartware

Only the C: drive is seen by Smartware. WD external is visable to and accessible via windows.

Smartware doesn’t backup external media.

Thanks for the response but when you start Smartware, you typically see a pictoral of the C drive on the left and and your WD drives to the right of that.  This is what I again see.  Not sure what I did to rectify my original problem.
