This is the "permanently unlocked" version of sys file 0x1D2. I don't know what that means, but I saw it in this thread:

Permanent ROM unlock without sending handshake.
This is not relevant to ATA password.

Maybe 0x1D1 is a container which stores all the security related information for the drive. If individual security modules are damaged, they could be restored from the backups in the container. I still think the solution could involve replacing the unknown user password data with known master password data.

You could test the master password on your donor by setting what you think is the real master password and then comparing the before-and-after dumps of 0x30A. If you have guessed the correct master password, then I would think that the two dumps would be identical.

0x1D2 can be carved out of 0x227 at 0x1C5000 - 0x1DBFFF.
0x1D2 can be carved out of 0x1D1 at 0x22000 - 0x38FFF.
0x30A can be carved out of 0x227 at 0x2F1000 - 0x2F1FFF.

The master and user ATA passwords are stored in 0x30A. They can also be carved out of 0x1D1 at 0x39000 - 0x3910F.

I believe that the master password in older Seagate drives was "Seagate" plus 25 spaces (0x20).

I tried this master password already but the two dumps after wasn't matched. So it's not the older master password.

Has anyone have this drive FW backed up ?

Thanks in advance

Could the master password be blank? That is, what about 32 spaces (0x20) or 32 zeros (0x00)?

Thanks a lot.
Writing sysfiles from same FW version didn't work too.

Unfortunately, I have exceeded the recovery time and the customer will come today to collect the drive.

Case not solved and I gave up.


Thanks for anyone trying to help.
