Setting BIOS HD password for NVMe on X1 Carbon Gen4

2016-09-23, 13:06 PM

On my old T420, I was able to set a HD password on my SSD in the BIOS so that if anyone ever stole my laptop and pulled the drive, they wouldn't be able to access the data without the password.

 

I'd like to do the same with my X1 Carbon Gen 4 with 512GB Samsung 950pro NVMe HD.  However, in the BIOS, I see no option to set a HD password.  I can set a power on password, but I don't think this means the HD is encrypted.  I assume anyone can pull the HD and read all the data.

Solved! See the solution

I couldn't get that drive to deal with a PW in my P70 or Yoga 260.  I tried a different NVME drive and it did work.  I think there are just BIOS problems associated with that sort of drive and the problems are still being looked at.

Has anyone had any luck with this issue?

 

X1 Carbon Gen4 with a Samsung 950 nvme.

 

I want the storage to be encrypted so one can't break into my system by removing the nvme and reading it externally.

I gave up and am using one of the models that Lenovo sells on new systems.

Which one are you using? If I'm going to spend the extra time and money, I'd like to make sure I get one that works

IMHO also consider using Bitlocker or a different crypto engine as well - as it is unclear whether SSD password is necessarily 'secure' and not bypass-able/back-doored, how the crypto keys are secured with the password, etc. - I have not seen Samsung publishing much information. Not that TPM is immune to attacks.

 

Also note that Lenovo uses a hash of password+model+serial to set actual SSD password so don't expect to unlock the SSD on a different brand/model laptop - this may be a positive - but may prevent data access upon laptop failure/decomission/etc.

Well, I prefer the SSD password because i it has no performance impact where bitlocker, etc have to use some amount of CPU. Your SSD is always "encrpyted" anyways and the controller essentially acts as an "unencryptor" whenever you read data. Setting a password just adds one extra step before turning on the "unecrpytor". There are certainly vulnerabilities. For example, if the password is entered, one can simply unplug the data cable and plug it into another computer and read off all the data. One reason why hibernate or off is preferred to sleep.

951a is similar to 950 Pro.  When I tried doing performance testing (on a different model) results were mixed and consistent.  I couldn't draw conclusions.  Both were fast.  For me, speed differences were more theoretical than actual.  Boot times were about the same.  The ATA security in the BIOS made me choose the 951a.
