Hi,

Recently we have been moving from Windows 10 to Windows 11 and the data backup what we have taken in Windows 10 is unable to access in Windows 11.

It is showing RAW in diskmanager. When I tried to mount in linux it reports it has ReFS partition and can't mount in it. I don't find any useful information how to get the data stored in ReFS HDD. Could you help?

    Hi,

    You can try the ReFSUtil tool to recover data from volumes that show as RAW in Disk Management. Open PowerShell as administrator and run

    refsutil.exe salvage -QA E:\ N:\WORKING N:\DATA -x

    Replace E:\ with your ReFS volume, and N:\WORKING and N:\DATA with appropriate paths for temporary and target directories.

    ReFSUtil | Microsoft Learn

    Run the following command to perform an offline scan and fix:

    Repair-Volume -DriveLetter E -OfflineScanAndFix

    Replace E with the letter of your ReFS volume

    Uninstall the patch KB5009557 if it's installed.

    ReFS volume appears RAW (version doesn't match expected value) after Windows Update | Microsoft Community Hub

    If you continue to experience issues, the file system could be corrupted, and you may try some third-party data recovery software or contact Microsoft support to recover the data.

    Hi Ian_Xue,

    I already tried refsutil and not useful in this case. It is not the corrupted Hard drive and it has valid ReFS partition. I tried some third-party recovery tools to check the files in it. They are still failing to find any valid information from my HDD. Finally, I found one of the PC which was installed with Windows 10 from where I have taken the backup. Once I plugged my HDD, it mounts properly, and I am able to get all the files back. I am really wondering why Windows have no information about how to recover ReFS partition data (Which was supported in windows 10 and no support in windows 11). Both windows 10 and the 11 are official images provided by our company.

    But thanks for your support and reply. For anyone take dump on Windows 10 please make sure the drive is not formatted to ReFS partition.
