T440s Crucial SSD and firmware password encryption

2014-04-08, 19:35 PM

Hello,

This post is directed at someotherguy because it is a follow through from another post.

 

I am opening a new thread because I think it is appropriate.

 

I took you advice in this thread: <link here> and used the password in the firmware to encrypt my SSD and abandoned

trying to get bitblocker working.

 

Now I have bought a new Crucial SSD 480GB (I need the space) and successfully cloned my existing system over to it. 

 

However the disk password option in the firmware is missing.

 

From reading around I understand this means that my new Crucial SSD is now in eDrive mode (your tool confirms this) and unfortunately you cannot reset a crucial SSD at this time back to ATA Security mode.

 

Crucial is replacing the drive for a new one as they except this is a problem their end.

 

My question is:  How do I make sure the new SSD from crucial does not go into eDrive mode by cloning/copying/installing windows 8.1?

 

I really would appreciate a comprehensive reply :-)

 

Clavain

To avoid Windows 8/8.1 from enabling the eDrive feature, the easiest way is to set a HDD password in BIOS Setup BEFORE installing the OS.  If the HDD password is set, eDrive cannot be enabled.

 

Microsoft also has a registry entry and group policy to prevent eDrive from being activated.  Contact Microsoft for more info about it.  Sample reg file is below:

 

https://dl.dropboxusercontent.com/u/62276273/disable_eDrive.reg

 

This reg file would need to be applied BEFORE the OS installer creates partitions on the drive.

FYI, a contributor to the Crucial SSD subforum has written a tool ("msed") that will PSID revert ("revertsp") crucial m500 drives.

Hi,

Someotherguy, Brendanhoar, ColonelONeil:  Thanks for all the help.  I used a little from everyone and got my drive encrypted.  Completely gave up on bitlocker, couldn't get it to work properly.  At some stage you have to give up and move on.  I'm using the SEP and Firmware option for encrypting my data.

 

The tip with setting the password at the start to prevent Windows 8 switching to eDrive mode was quite clever, since ATA-Security and eDrive are mutually exclusive.

 

 

BTW I used Paragon's Disk Manager 14 Suite to clone/copy my existing drive.  Worked a treat.

 

Every now and then when booting the T440s doesn't see the drive and reports the drive is missing :-(, but a quick reboot has always solved the problem.  Not optimum, but I can live with it.

 

Thanks again everyone for the help,

Clavain

Clavain:

 

I was wondering if you ever got this resolved?

Newer firmware for the drive / ot T440s perhaps?

Maybe not an issue for you, but I don't think my heart could take it ....  :smileysurprised:

Hi JWooden,

 

Just a quick update.  I haven't had the problem with the missing drive since I last posted.  Everything is fine.

Thanks for the update Clavain!

Very odd, but I'm glad it's not a continuing issue.
