This is a similar problem to one reported elsewhere here though mine has not been solved by the solution to that (they found a folder containing millions of files)......
I have a 1TB WD hard drive that backs up the documents and photos on my laptop (I don't copy them across, I let the WD Smartware software handle that). The total storage of these items on my laptop is approx 300GB, yet the WD hard drive is showing about 873GB used ! I have checked the Properties of the individual folders showing on the WD hard drive and the sizes total approx 300GB which is what I expect. So why does the hard drive show it's got 873GB of data ?
