Bitlocker HW Encryption/eDrive Samsung PM compatibility

Hi Everyone,

I was just trying to set up Bitlocker eDrive on my Latitude 5521 which included the SSD PM991a.

However I was not able to enable it after following steps:

  • Tried to activate eDrive with Samsung Magician, but Disk not recognized
  • Performed Data Wipe through BIOS
  • Deactivate "Block SID authentication" in BIOS
  • Enable Secure Boot
  • Perform Fresh W11 install

After that I tried to activate OPAL 2 encryption with sedutil. However there the tool showed me that the drive would not support OPAL 2.

After that I exchanged the Samsung PM991a with a Samsung Evo 970 and Bitlocker eDrive works now (with the steps I described above), however now I have this Dell Bios Bug concerning Dell Security as described here (but thats a different topic)

So did anybody of you guys manage to set up Bitlocker eDrive with an original Dell Drive (Samsung PM...)? According to the specs they should provide HW encryption ...

For those who are interested:

I did not manage to set it up with Bitlocker but with Sedutil i finally succeeded. 

Following hints might help:

  • As far as my research led me: There are different types of Samsung PM991a SSDs, some are SED and some are not
  • A good sign for SED support is if you find a PSID on the Sticker of the drive
  • Use different Forks of Sedutil, the original version showed me no OPAL support for my drive, whereat the Fork of Chubbyant worked for me
  • Enjoy the super fast SSD with HW Encryption ;)

@josef512 thanks for the reply! But somehow your answer got deleted!

Anyway I tried to contact dell technical support before, but I didn´t manage to get any answer since obviously my support is expired! (To be honest I don´t get why I can´t even ask such general question without paying for further support!)

So it looks like there is no solution for this issue.
