Hello,

Yes, there are differences between the ReFS versions used in Windows Server 2019 and Windows Server 2022. Windows Server 2022 uses ReFS version 3.7, while Windows Server 2019 uses an earlier version.

These versions are not fully backward compatible, which is why your HDD formatted with ReFS on Windows Server 2022 is detected as RAW on Windows Server 2019. The newer features and enhancements in ReFS 3.7 are not recognized by the older version used in Windows Server 2019.

To access your data, you will need to use a system running Windows Server 2022.
