What does HRESULT 0x80310095 (FVE_E_REMOVAL_OF_DRA_FAILED) mean?

FVE_E_REMOVAL_OF_DRA_FAILED

Read this as a state-machine result

FVE_E_REMOVAL_OF_DRA_FAILED is a BitLocker facility HRESULT, not a Win32 filesystem error wrapped by an application. In this case the caller tried to remove a data recovery agent protector through an API path that does not own DRA certificate lifecycle.

A BitLocker key protector wraps access to the volume master key. TPM, TPM+PIN, startup key, recovery password, password, certificate and Network Unlock protectors have different volume and policy rules; changing one is not the same as decrypting the volume.

What the code does not prove

The closest misleading interpretation is a missing DRA certificate or failed private-key authentication; the removal mechanism itself is unsupported here. 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

1. Record DRA certificate thumbprint, certificate store, protector list, Group Policy DRA configuration and the tool used for removal.

Protector inventory should be treated like a set of independent unlock routes. Record protector GUID and type; the presence of a recovery password does not prove that the PIN/password protector being changed exists.
