WIndows Server 2022 Partition Lost - ReFS to Raw

Hello, after leaving site for a few days, my main share partition is now RAW, where it was Refs 3.7 and was functioning well except dedupe never ran. I checked updates but it was just ones pending download, so I sort of ruled that out a bit from other research but I feel like I am missing something. I downloaded Hetman Raid Recovery where it sees the drive with Refs and its easily distinguishable, but I have not run it completely to recover the data as I do not have anywhere to put this amount of data. It's about 20TB+

    Hi,

    You can try enabling the file data integrity stream to check and repair the volume. Open PowerShell as administrator and type the following command. Get-Item 'C:' | Set-FileIntegrity -Enable $True

    If the update KB5009557 is installed on Windows, uninstalling it may resolve the problem.

    If the ReFS volume is still showing as RAW, you can use ReFS salvage to recover data from the volume by running the following command

    refsutil salvage -QA <source volume> <working directory> <target directory> <options>
