Just got off the phone with tech support on this issue. They gave me 3 options to resolve this issue.
#1: Use the drag and drop method for backing up files
#2: Use the WD SmartWare software to backup files
#3: Use a 3rd party application
Option 2 Slows the computer down because it is continuously running and looking for files that are changing. The high CPU usage is unacceptable to me. So in a round about way, WD support is telling me not to use there software to backup the computer because there is no way to avoid the high CPU usage.
I had another HD (a competitor) which had there own software and it ran beautifully it was always backing up the system and I never had any performance issues.
