I have done the same thing - i didn't copy file manually but used the software. Have been searchign forums all night to figure this out!
Having used the WD SmartWare automatic backup, does this mean i cant view files as i would normally? i.e. open them in Word or whatever it is I am using, work on them and save them to the Passport when out and about?
Do i need to also transfer files over manually to do this?
