STATUS_FVE_INVALID_DATUM_TYPE
Meaning and context of STATUS_FVE_INVALID_DATUM_TYPE
A BitLocker management datum is structured metadata, not a user file. This status says the reader encountered a type it does not recognize, which makes version compatibility, malformed metadata, and unsupported management information more relevant than ordinary access permissions.
Record the Windows build, BitLocker version reported by the volume, management tool, and whether the volume was created or modified on another Windows release. Do not edit the volume at sector level or remove protectors simply because an older tool cannot interpret a datum.
Use a supported current management interface to inspect the volume, then preserve recovery material before attempting migration or recovery. The WMI provider and manage-bde -status reveal the high-level state without requiring raw metadata changes.
