Since about 2 or 3 revisions ago the deep scan does not work regardless of filter chosen; pics, vids, *.*. When running through the process everything "appears" to run normal, however, upon completion I get the message "Incorrect Function" and there are no files to "recuva". I have only run Recuva on various SD cards but not the hard drive unless inadvertently since it automatically switches to the "c:/drive" after a run.
I did discover later that if I turn off the deep scan the files appear as expected.
