Question Lock / Unlock HDD Momentus 7200 FDE.2 250GB from Seagate

Recently I had bought some HDD Momentus 7200 FDE.2 250GB from Seagate factory. Following is the summary information of HDD:

SID: JT5J0 KH26X 9NN1T 0L475 US948
SN: 5VGAE410
Model Number: ST9250412AS
PN: 9PU142
FW: 0002SDMA

Now I am researching to program a Driver and Application on Linux for VIA6421A PCI Card to control Lock/Unlock those types of HDD.

The first time, I have sent the TRUSTED RECEIVE command with the following parameters to HDD via the VIA6421A PCI card (security protocol=00h, sp_specific=0000h) And I have received the security protocol with code :F0h. Please see the Attachment file more details.

I know , this code said that security protocol is defined by manufacturer (Seagate company). And I also find out the information on Internet and see to program a software for managing those FDE HDDs , I must use the "DriveTrust Security API". But unfortunately I didn't find any information about DriveTrust Security API.

I just want to ask for You in this case ( security protocol with code :F0h) what I must do the next steps ? and What must I read documents?

As far as I know this is a proprietary API that uses enhanced ATA security features. You might contact Seagate for further information though I suspect a hefty licenceing fee might be involved as they certify third-party applications for their security products. The enhanced ATA Security API can be used if you wish to authenticate the drive using
BIOS passwords instead of software.

A bit more information can be found here:

Trusted Platform Module

This drive is used with Trusted Platform Module BIOS systems. Essentially, there's a smartcard soldered onto the motherboard that is the trust broker. You need the Trusted Platform Module storage API.

This link has some information:

If that link doesn't work, search terms trusted platform module "TRUSTED RECEIVE" will get you started.

The politics of attempting to connect to the very secret TPM with Free software are daunting. Some TPM people <cough>MICROSOFT!<cough> would be very unhappy to share.

Implementing a TPM under Linux isn't as daunting as it once was. A couple of reference links are below (Though perhaps a bit dated now. Detailed Trusted Platform info can be had from the Trusted Platform Initiative folks.
