how to fix windows corrupt file?

  • Not KPA related but windows 10/7

    In the wisdom of making good use of the "isolation-time" i replaced my win7 OS harddrive with a new one and installed win10 on a fresh drive.

    I have other drives on the same PC that contain audio files and projects, therefore whichever OS harddrive i use i can still access the same data to the other drives, labelled the same on both OS. That was the logic and thinking, anyhow....


    All seemed well- i could i open and work on a project file in either OS (the same DAW software installed on both OS)

    however, for some bizarre reason, win 10 has corrupted the file (setting permissions and ownership on the common disks?) and returning back to win 7 (because it was running stable) the file appears to have been corrupted. All i done was open it in win10. Didn't even hit save. Frustrating as i've spend the last few weeks editting this particular project.


    Any ideas how i can recover this file, on either OS?
