The Crucial M500 SSD is OPAL and TCG compliant to allow hardware based encryption with Windows 8 bitlocker. I am cannot enable this feature due to a hardware issue.
After installing Windows 8, I disable the TPM requirement for bitlocker (no TPM on the motherboard). Then, while enabling bitlocker, I let it run the check that causes the computer to reboot. Upon rebot, I get the "bitlocker could not be enabled - your computer does not support bitlocker hardware based encryption" error. If I enable bitlocker anyway, the SSD will be encrypted with the hardware encryption. However, after a reboot with the encryption enabled, it shows the bitlocker recovery screen and after entering the recovery key, the recovery fails.
I have the latest BIOS (V66 from 2013-5-21). It is running in AHCI mode and the SSD is formatted as a UEFI drive (main partition, UEFI partition, and a recovery partition).
What I have tried without success:
-Disable legacy boot support
-Disable network boot
-Disable secondary SATA ports
-Try the 3Gbps Intel ports
-Try Windows 8.1 preview
Is there a know compatibility issue with the dz77gal-70k and bitlocker hardware based encryption? Is there any workaround that I can use to get this to work? It appears to be a motherboard issue as I can enable the encryption just fine, it's booting afterwards that is the problem.
There is a thread on the Crucial forms related to compatibility problems with the M500 and bitlocker.
Bitlocker Drive Encryption is a feature included on Windows 8 Pro and Enterprise only.
In order to enable Bitlocker on your system, the processor installed needs to have the Intel® Trusted Execution Technology available.
So, could you please provide me the model number of the processor in order to double check if it comes with this advanced technology?
Thanks for the reply.
I am unaware of any bitlocker requirement for TXT support. Bitlocker does not even require a TPM according to their documentation.
Hardware requirements for bitlocker:
I am using an i5-3750K. I have tried both the password and USB key authentication methods and the result is the same.
I tried both SATA 6Gbps ports (SATA 0/1) as well as a SATA 3Gbps port. I was unable to boot from the 3rd party controller (Marvell?) normally but I only tried that for a short while.
Normally the hard drive needs to be connected to the SATA 0 port.
I'm going to try and replicate this behavior. I will provide you the results ASAP.
