STATUS_FVE_POLICY_USER_DISABLE_RDV_NOT_ALLOWED
Meaning and context of STATUS_FVE_POLICY_USER_DISABLE_RDV_NOT_ALLOWED
RDV in this status refers to a removable data volume. The operation was rejected by BitLocker policy: it is not a failure to decrypt sectors and it is not corrected by using a different drive letter or reconnecting the device.
Determine which policy source controls the device—local policy, Group Policy, mobile-device management, or a security baseline—and record the target volume classification. Changing an individual protector cannot override a policy that prohibits users from turning off encryption on removable media.
Review policy and recovery requirements before changing the rule. BitLocker configuration is commonly applied when protection is first enabled, so an environment can contain volumes whose existing state and current policy need to be evaluated separately.

Native status interpretation
STATUS_FVE_POLICY_USER_DISABLE_RDV_NOT_ALLOWED is 0xC0210027, an NTSTATUS error value. AllStat describes it as “Group policy does not permit turning off BitLocker Drive Encryption on roaming data volumes.”. The first useful question is which native API, IRP, protocol operation, or subsystem in the kernel, native API, or subsystem that returned the status produced that status.
Debugging sequence
- Preserve this result before RtlNtStatusToDosError, HRESULT conversion, exception translation, or provider-specific remapping removes information.
- Log the operation associated with fve / policy / user / disable / rdv, the object or handle type, process and thread identity, and the state transition immediately before the return.
- For kernel I/O, keep the device stack, IRP major/minor function, request parameters, completion routine, and the first component that completed the request with this result.
Recovery considerations
A retry is appropriate only after the owner of this result has changed the state described by “Group policy does not permit turning off BitLocker Drive Encryption on roaming data volumes.”, or when its contract explicitly marks the status as transient. If the value reports corruption, invalid format, access policy, or a lifecycle mismatch, preserve evidence and correct that cause before repeating the request.
