Re: Setting BIOS HD password for NVMe on X1 Carbon Gen4

2017-02-03, 6:35 AM

I did not had any problem to set up the HD passwprd on the X1 Yoga which is similar to your X1 carbon. I have the bios 1.21 and I guess you may have to enable the supervisor password. YEs i agree the password is an efficient way t save your data.

Yes I have a 512 MB SSD. It is a NVMe SAMSUNG MZVKV512B.

Yes, apparently it does not work with the Samsung 950 pro eventhough it should be supported. It only works with the versions that Lenovo supplies.
Will it allow you to use your fingerprint instead of the password? In lieu of the HD password, I set a power on password so I had something and I have to admit that I've gotten use to using my fingerprint eventhough it is less secure

Bitlocker with a SED uses no additional CPU time and has no performance impact. All it does is take ownership of the keys the SED is using anyway as it is always encrypted.

 

Check out the AnandTech results or similar - there is no delta. With AHCI SSDs we've used it for years and there is no delta you can benchmark anything you like.

 

Even software Bitlocker uses AES acceleration instructions and you're pretty much limited by memory bandwidth so unless you're doing heavy I/O the security may be worth it. IMHO.

Finally got my SM951a cloned the data over and got the password setup.

It's nice to be encrypted finally.

 

Now once I booted up the new drive, it picked up the microsoft driver.  I could not find a driver on the samsung site.  Also Magician could not find the drive.  Do you know where I can get the samsung driver and get it to work with magician?  I'd like to know how much data has been written to the drive since I bought it used.

Samsung Magician is only for their retail drives.  As far as I know, it doesn't work with OEM drives like SM951a.  However the info you are looking for is stored in the NVMe device firmware.  I have a tool which can read it:

 

https://dl.dropboxusercontent.com/u/62276273/eDrive/check_NVMe/check_NVMe.zip

 

Extract and then run "check_NMVe.exe 0 02" from an administrator command prompt.  (This assumes that your NVMe disk is the only disk in the system).

 

It will display the NVMe log 0x02 data.  You are interested in the "data unit written" field with is displayed in hexadecimal units of 512,000 bytes (thousands of 512-byte sectors) so you will want to convert to TB written to get an idea of how used your drive is.  If you need help with that conversion, just post the output here.

hmm, it says "DeviceIoControl failed, get LastError() = 1" "Are you sure this is an NVMe SSD?"

Which driver are you using?

I'm using the Win10 built-in driver.  What are you using?

Oh.  The Microsoft Win7 NVMe driver is half-baked and doesn't support the interfaces that my tool uses.  Honestly you are wasting the capability of the NVMe drive by running Win7 on it.  I have never tested my tool on Win7 + samsung driver, but if you want to give it a try, you can find the driver here:   http://www.win-raid.com/t29f25-Recommended-AHCI-RAID-and-NVMe-Drivers.html

Another idea is to boot to a Win10 ISO, press shift-F10 to get to a command prompt, and then run my tool from there.  Though you may have to play around with the 1st parameter to find the drive number that corresponds to the NVMe SSD.
