My WD Passport has been great, until the last back up. It made extra copies of some of the most recent files. The only thing I know changed, was I updated the WD SmartWare software.
I am primarily refering to iTunes files as they are mostly what I back up.
Can I fix this easily? Or must I blank the drive and start again?
By default Smartware will save 5 copies of each file that you edit. You can manually change this settings from the Smartware Setup tab and then on file history.
You can manually explore the smartware.swstor folder and delete the duplicate files. The new files that are backed up will only have the number of copies that you select.
