Open for suggestions for a fingerprinting tool. I think that's what they are called.
We are copying NASA imagery to make available to the public. They send us a hard drive with about 10,000 images and we copy them to a drive then return the original.
I'd like a tool that would compare the 2 drives to make sure everything was copied correctly. Then something that would be able to tell if some file had degraded, went missing or been changed over time.
