WDBAAF0010HBK Can not load data into pc source

Had a prolonged power failure…disk went blank…I can see the drive (G) and can drag/drop data in it…When opening WD smartware the icon on the left representing the OS © data for backup is empty…how to rectify situation?

Try uninstalling Smartware and then do a clean installation of the latest version. 

Uninstalling WD SmartWare Version 1.6.x and earlier from an external drive’s VCD on Mac OSX does not remove it from the Application folder 

Smartware download
