FVE_E_AD_INVALID_DATASIZE
FVE_E_AD_INVALID_DATASIZE indicates that a BitLocker recovery attribute retrieved from AD DS has a length that does not match the expected format. Treat this as a directory-data integrity or provisioning issue.
What to check
- Verify that recovery data was written by a supported BitLocker deployment path.
- Confirm that directory replication has completed before comparing recovery objects across domain controllers.
- Keep an independent recovery method available while the AD DS record is investigated.
