I recently had an indicdent where I discovered that some image folders on the drive that I did a backup of were damaged which resulted in an incomplete/broken backup. Fortunately I managed to recover the damaged pictures from an old computer.

old computer and other devices (no damaged files ) –> backup (had some damaged files) –> backup of backup (also got the damaged files)

I know that the drive shouldn’t had been used the state where files got damaged in the first place, but I’d like to know if there’s a tool that can scan for inconsistencies among the files and identify if there are any damaged ones? Preferably without having to compare with the original files.

I discovered the broken images by pure luck (it was only a couple of folders), and the thought of not doing this and continuing to backup broken files scares me at night when I try to sleep.
