FVE_E_EDRIVE_DV_NOT_SUPPORTED
The failed prerequisite
FVE_E_EDRIVE_DV_NOT_SUPPORTED / 0x803100B4 marks a rejected BitLocker transition: BitLocker To Go discovery volumes are not supported when the target uses hardware encryption.
Hardware encryption is not inferred from the SSD marketing name. Verify the encryption method reported by BitLocker and the drive capability returned through the storage and volume-encryption providers.
Diagnostic map
| Layer | hardware-encrypted drive negotiation |
|---|---|
| Proof to collect | hardware-encryption state, removable-media role, discovery-volume request and compatibility requirement for older readers |
| Different condition | a discovery volume rejected because of filesystem type or Group Policy |
| First safe change | choose software encryption if a discovery volume is genuinely required, or omit the legacy discovery feature |
Hardware-encrypted drives add firmware, storage-driver and drive-security state below the normal BitLocker volume provider. BitLocker can reject the hardware path before conversion starts, and policy may or may not permit a fallback to software encryption.
A focused verification sequence
- Record hardware-encryption state, removable-media role, discovery-volume request and compatibility requirement for older readers.

| Stage | How to interpret it |
|---|---|
| Before the call | Record the target identity and the pre-call hardware-encrypted drive negotiation state. BitLocker To Go discovery volumes are not supported when the target uses hardware encryption. |
| At failure | Preserve hardware-encryption state, removable-media role, discovery-volume request and compatibility requirement for older readers. |
| After correction | Choose software encryption if a discovery volume is genuinely required, or omit the legacy discovery feature. |
