    How to recover 'not shown' files?


    I have a WD 1 TB external hard drive.

    It shows that 850 GB is free of 931 GB. Hence the total size of files within the drive should be ~80 GB. However, I can only access 30 GB of them. The others are not visible although I set the 'Show hidden files, folders, and drives' on Folder and search options.

    Is it possible to recover them?

    Running

    Code:
    attrib -h -r -s /s /d d:\*.*
    didn't work.

    Did you also unset Hide Protected Operating System Files?
    Schedule a check disk: chkdsk d: /f

    Suggest: Try deleting any system restore points on that drive. Disable "system protection" for that drive if you don't need it.

    Option One here:

    System Protection Restore Points - Delete

    Get WinDirStat Portable:

    PortableApps.com: Portable Software/USB - Browse /WinDirStat Portable at SourceForge.net

    Scan the drive and review the results.

    Additional info:

    Perhaps read this thread: C: Drive Used/Free Space WAY Different Than Actual?

    In particular read through the information contained in the link in this post:

    When explorer calculates folder disk space it only includes files that would be visible. If explorer is configured to not show hidden files they will not be counted. This was a design choice made a long time ago.

    Also not included will be the System Volume Information folder and others that the user does not have access to. Even an elevated admin account cannot access this folder. As Explorer runs under the users account it is not able to access these folders either.

    Calculating the space consumed by a folder in NTFS is very complex and the results are at best only an approximation. Many largely arbitrary decisions were made in the design. It is not the Windows is lying about the size. The question is: what is the truth? There are many equally valid answers and they could produce very different results.

    See this for more:
    Computing the size of a directory is more than just adding file sizes - The Old New Thing - Site Home - MSDN Blogs

    The blog is by Raymond Chen, a developer with Microsoft.
    So understand that drive size minus total size of files shown in explorer does not equal free space.

    You can look at ways to free up space if you are running low on space. If files seem to get added to a drive regularly - increasing used space with no obvious cause then you could investigate. Just don't bother with adding up file or folder sizes.

    This is the output of attrib and chkdsk:
