I've been trying hard to get my Crucial m500 SSD hard drive to work in edrive (hardware encryption) mode with the w520. I've read several other threads related to the process for different Lenovo machines, but I haven't seen much discussion on the topic for the W series laptops as of yet.
Here's what I've tried so far:
When I enable bitlocker encryption, I'm given the choice to either do the existing data only or the whole drive. According to Crucial tech support, that's a telltale sign that edrive is not being used. As further confirmation, I've also run checked edrive status using this method:

W520 BIOS doesn't support eDrive. I highlighted in red the reason why, from the below URL. At the time W520 was developed this protocol (and UEFI 2.3.1) didn't exist yet. We don't have any plan to retrofit the older systems to add this support now.

I was wondering if you could tell me if this is also the case for the L430. I have tried updating the firmware of the L430 to 2.66 using the BIOS update utility. It still does not work. So my question is, does the hardware itself in the L430 not support the EFI_STORAGE_SECURITY_COMMAND_PROTOCOL? From my limited research, I can not tell if the EFI_STORAGE_SECURITY_COMMAND_PROTOCOL is strictly a firmware thing or if it also requires some speicifications in the hardware of the machine. Although, my experience seems to lean towards the latter.
Also, can you confirm that the L460 does indeed support the requirements for eDrive? If so, we may replace our L430 with it.
Just FYI, the drive we are using is the Intel SSD Pro 2500 eDrive.

Though I have never personally tried it, and I don't know for sure, I believe L430 with BIOS version 2.x should have all the prerequisites to support eDrive. You would have to enable OS Optimized Defaults, then load BIOS default settings and re-install Win10. Have you tried that?
EFI_STORAGE_SECURITY_COMMAND_PROTOCOL is implemented by UEFI platform firmware (e.g. BIOS).

Yes, I have tried that.
Spent the last few hours using a Samsung 850 EVO drive in the L430 and I finally got it to work.
So, verified that the L430 with BIOS 2.66 does work with edrive with the Samsung 850. Not sure why it didn't work with the Intel drive. Maybe I'll play around with it more tomorrow.
Thanks for your input.
