I am using Windows Photo Gallery and Vista with 87GB free space on the main C:\ HD. I have 469GB of scanned photos on WD My Passport Essential SE - 1TB, which I will name as Unit #A. When copying the 469GB and pasting these photos to another WD My Passport Essential SE - 1TB with 900 GB of free space (my Unit #B) —In the beginning, I could copy about 90GB successfully from A to B but then the amount decreased on each copy operation to a lesser amount to where now I cannot copy any photos from A to B.
The copy process starts out with a Dialog Box saying, “Preparing to Copy” and begins showing the number of files it is preparing to copy. Then about 20 seconds later – The Dialog Box disappears without showing me the approximate hours and minutes it will take to copy these numerous picture JPG and TIF format files to my Unit #B.
I do not get any Error or Warning Messages!
Is there some sort of a “Clipboard” involved in the Copy process that might be “Full”?
Also, I originally copied a large portion of my 469GB worth of pictures files to WD #A when that External HD was assigned a Drive letter of “J” automatically by Windows Vista. Sometime later Vista changed the HD letter indicator from “J” to my current “H” drive.
When I attempt to copy a large batch of picture files from WD #A to #B – some of these pictures might have originally been copied in the WD “J” Drive or the current WD “H” Drive. Could this be the problem?
