What does NTSTATUS 0xC021003D (STATUS_FVE_NOT_DE_VOLUME) mean?

STATUS_FVE_NOT_DE_VOLUME

Meaning and context of STATUS_FVE_NOT_DE_VOLUME

This status is about the Device Encryption management model, not a claim that the drive has no BitLocker data. The selected volume is not one Windows automatically manages as a Device Encryption volume, so a Device Encryption-specific operation is not applicable.

Identify whether the target is the operating-system volume, a fixed data volume, removable media, or a volume managed through another BitLocker workflow. Use the normal BitLocker tools to inspect its conversion, protection, lock, and protector states before deciding which management path applies.

Do not equate Device Encryption with every BitLocker deployment. Windows can use BitLocker through different volume roles and administration surfaces, and an operation designed for automatic device management can legitimately reject a manually managed volume.
