In case anyone needs help with the message “Attach a supported WD drive” message in WD Security, I was able to resolve the error in my specific case by doing the following (I did it in Windows 7 but should work for XP and 8 if WD Security works on those OSs, must be done with administrative privileges):
- Close WD Security
- Navigate to the Control Panel, Administrative Tools, Services
- Look in the list for a service with the name “WD Drive Manager”, double click the service
- If the Startup type is set to Disabled (which in my case it was), change it to read Automatic then click Start, then Service status should read “Started”. Click OK
- Close the Services and Administrative Tools window, then open WD Security and the application should find the drive.
Good luck!
