Greetings all.  I just joined, although I've been a software engineer for over 40 years and have run this business for 7.

 

A week ago a customer dropped off a Lenovo ThinkPad that used to belong to his former employer.  It is running Windows 7 Enterprise Edition.  The internal SSD is fully encrypted using McAfee encryption.  I don't know much more about the encryption product, and he knows less.  He wanted to continue using this computer after leaving his job, so we changed his account to be local and changed the domain to no longer be his employer's.  Then we rebooted, and the computer bricked.  We were still able to get past the encryption because we know the password, but Windows presented only one login account - his former employer's administrative account.  His was gone.  I did some more work ("more work" means I don't remember what else I did) on Windows and somehow now Windows has stopped booting to even the password login screen, although it still asks for and accepts the encryption password.

 

So here's my question:  I want to attach this drive to a SATA-to-USB adapter and connect it to another computer, and retrieve his data using the McAfee encryption password.  Is this possible?

 

Many thanks.

I am not sure but from reading the pdf here it seems it uses pre-boot authentication and possibly the TPM. If that is the case I don't think it would work but it can't hurt to give it a try.

 

■ Utilizes the Trusted Platform Module (TPM) 1.2 and 2.0 hardware to provide a transparent user experience.
