I’m having a lot of trouble getting bitlocker edrive (hardware encryption) to work. I have a Gigabyte TPM module installed, CSM disabled and UEFI bios use confirmed. I’ve followed the steps exactly for my Evo840 with Samsung Magician, and Gigabyte’s support staff assures me that the motherboard does support edrive. However, every time I get to the step of enabling encryption I get the “Encrypt part of drive or whole drive” question indicating software-based encryption.
As a test, I installed Windows 8.1 to an old SATA drive instead and then activated bitlocker on the Samsung SSD as a secondary drive. That worked great, and when I run the command “manage-bde.exe -status f:” it confirms that the ssd is indeed hardware encrypted in this secondary drive position.
I've heard that this indicates that the motherboard doesn't support EFI_STORAGE_SECURITY_COMMAND_PROTOCOL, which is required to use edrive on a boot drive. How can I confirm that though?
