  1. Thank You, Thank You, Thank You! had a situation where ReFS died on a backup target server. With utility was able to recover files. for me had to upgrade server to 2019 to be able to use utility but so thankful Microsoft came out with tool. But … MS needs to mark bad sectors or corrupt files and let you know but not completely shutdown the filesystem Looking in logs there was an issue with ONE file! One, smh, had no clue that ReFS would do this. It is having me rethink how we will do our backup targets.

  2. Thanks for details
    However, I’ve encountered the following when trying to recover corrupt Mirrored ReFS drive when one drive stopped working. Instread og allowing access to data on the good drive, ReFS reset the drive and now shows up as empty. Have disconnected the bad drive and get the following share access flag issue when running the salvage command. Anyone have any ideas?
    C:\WINDOWS\system32>refsutil salvage -FA D: C:\salvage\working C:\salvage\ -v -x

    • Hi Paul,

      Does the Volume ID match with the GUID of your failed volume? Please use the following PowerShell command to quickly determine volume GUIDs:
      Get-WmiObject -Namespace root\cimv2 -Class Win32_Volume | fl DriveLetter, DeviceID

      Any luck with the other refsutil command-line options, like -D for diagnose or -QS for Quick Scan ?

      Best regards,

      Roland.
