FVE_E_FIPS_PREVENTS_RECOVERY_PASSWORD
Read this as a state-machine result
FVE_E_FIPS_PREVENTS_RECOVERY_PASSWORD is a BitLocker facility HRESULT, not a Win32 filesystem error wrapped by an application. In this case effective FIPS policy blocks creation or use of the numerical recovery-password protector in the applicable Windows implementation.
FIPS-restricted operation changes which protector, export and key-derivation paths BitLocker may use. The volume encryption algorithm and the protector workflow are separate layers, so a FIPS-related HRESULT should be traced to the exact protector or key-management call.
What the code does not prove
The closest misleading interpretation is a malformed 48-digit password or a missing recovery record, both of which occur after a numerical protector is allowed. Verify the returning method and state transition before assigning the incident to disk corruption, TPM failure or bad credentials.
Inspect the target, not just the message
- Record effective System cryptography policy, existing protector types, Windows version, escrow requirements and the command that attempted to add or use the protector.
FIPS mode does not translate into “turn encryption off.” It constrains algorithms and key-handling paths, so the correct remedy is to select a permitted protector and escrow design.

State checks specific to FVE_E_FIPS_PREVENTS_RECOVERY_PASSWORD
| Stage | How to interpret it |
|---|---|
| Before the call | Record the target identity and the pre-call FIPS-restricted key management state. Effective FIPS policy blocks creation or use of the numerical recovery-password protector in the applicable Windows implementation. |
| At failure | Preserve effective System cryptography policy, existing protector types, Windows version, escrow requirements and the command that attempted to add or use the protector. |
| After correction | Choose a policy-compliant recovery method or change the approved policy centrally; do not repeatedly regenerate numerical passwords. |
