I am sure it did at one time but I cannot back up / copy by C: Drive to my WD My Book Essential? No trouble with the other files (My Documents etc) and I have more then adequate space. But since accepting WD Updates and keeping current with the software, I am not able to copy / back up by system files and the C Drive (programs etc listed as Preload C)?? Maybe I never have been able to but that is why I purchased the WD for a complete back up.
I am using Windows XP and all software updates have been accepted. Are their some setting that I need to change?
