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.

    I wouldn’t use the drive anymore to be honest.
    Had a similiar case when browsing through family photos on my Samsung SSD drive and discovered a couple corrupted images / videos.

    The next day that changed to corrupted folders but thankfully I had everything mirrored on various other drives.

    Coincidentally this started after plugging the SSD into a new USB-C enclosure - it was in a USB 3.0 enclosure before. After all that it reported a wear leveling count of 3 but apart from that SMART seems fine. Still not using it for anything important.
