    Robocopy - Fails to Copy All Files, Doesn't Log Failures


    I'm frequently copying large folder structures using Robocopy and I'm finding more and more cases of files NOT being copied and the log doesn't mention anything. Is there any known bugs or reasons for such behavior that could explain why this is happening and how to keep it from happening?

    Robocopy vs Copy-paste

    I hesitate to get too involved in this because I continue to believe, as I said before, that the most effective method is to use RoboCopy error codes [Exit codes] to identify the existence of a prior failure and to use that result to trigger a repetition of the previous RoboCopy command.
    - Repeated failures might require human intervention in identifying causes
    - In my own scripts, I allow half a dozen repetitions with progressively lower /MT:nnn values [down to the limit /MT:1] before I identify the process as being incapable of completion without deliberate investigation.

    But, if listings are to be used, then including /XA:SH will suppress directory listings caused by changed SH files [such as thumbs.db files]. This command

    Windows doesn`t start. Authomatic repair doesn`t work.

    Thanks again!!

    I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

    I`ll do it and I`ll be updating this thread when I have the report.

    I ran SeaTools. These are the results:

    Robocopy vs Copy-paste

    Actually, that command won't list files that are not being copied BUT it lists all the directories that it traverses. To suppress that. simply tack on a /NDL (No Directory Listing).

    In the sample output below, note that the folder I am mirroring has 820 directories and 2708 files. The folders are already synced so not a single file or directory is displayed in the output.
