I have a few hard drives that appear to have been duplicated and I want to see what files appear one one drive that aren't present in the other.

HxD Compare

 

EDIT:
Never mind.

This will compare individual hex bits but not files.

simplest solution : make lists of files and the compare the lists with any file compare tool.

 

> redirects output so instead of seeing on screen, the list of files gets written to filelist.txt

/S means browse through folders

/OG means order files and place folders in front of files

/B means bare format (list only filename and extension, and path if /S is selected )

 

dir c:\ /B /OG /S >C:\filelist.txt
