What does NTSTATUS 0xC0210014 (STATUS_FVE_KEYFILE_INVALID) mean?

STATUS_FVE_KEYFILE_INVALID

Meaning and context of STATUS_FVE_KEYFILE_INVALID

The removable media or file was reached, but its contents could not serve as valid key material. That differentiates this result from STATUS_FVE_KEYFILE_NOT_FOUND, which stops before a valid candidate file can be read.

Confirm that the material was created for the intended volume and was not truncated, replaced, or copied from a different device. In recovery workflows, match the displayed recovery-key identifier to the stored record instead of judging a file by its name or USB drive letter.

Do not repeatedly alter firmware, TPM ownership, or partition data to correct a bad external key file. Use a known recovery method or recreate the appropriate protector only after the volume has been unlocked through an authorised path.
