Unable to activate sed hardware encryption with Bitlocker RRS feed

  • Question

  • Hi, I am unable to activate hardware encryption/eDrive on a crucial mx200 ssd (which is tcg opal 2.0 compliant) since Bitlocker falls back to software encryption. From Bitlocker logs (eventviewer->applications and services logs->Microsoft->Windows->Bitlocker-API->Management) I can see this warning event

    BitLocker failed to initialize hardware encryption for volume C:.
    Drive is not provisioned for use with BitLocker hardware encryption:
    Hardware-based encryption is not activated on this drive.
     <Event xmlns="">

    Unluckily it does not state the actual reason but onyl a general message "Drive is not provisioned for use with BitLocker hardware encryption:". Has someone any idea ? Here follows some information about the system:

    - Windows 10 Professional 1511 (build 10586.104)

    - Uefi and SecureBoot are enabled in bios (all default keys provisioned) and they are actually active in msinfo32 (Bios Mode UEFI and Secure Boot Mode On). There is no Compatibility Support Module option in bios, so I hope it's actually disabled (is there any way to check it ?)

    - The laptop has a TPM chip, but it is disabled in BIOS (sealing keys with hardware configuration is not needed, a password prompt at boot is enough). No TPM device is present in Windows devices and the group policy has been changed to Allow Bitlocker without a tpm chip ("Require additional authentication at startup" enabled and checked "Allow BitLocker without a compatible TPM" )

    - Using standard SATA drivers from Microsoft (no intel rapid storage driver). SATA mode in bios is AHCI (not raid)

    - Using hdparm on drive it states that it's in the frozen state (not locked, not enabled) in the security section. Digging in forums someone suggested to SecureErase the drive with its PSID and reinstall it, but I would like to know why since the drive is brand new and it's the first installation of Windows and no password has ever been set before.

    Update: standard opal sedutil-cli works (, here it is there query output
