In that case I would recommend using a different machine

I even bought an old laptop cheap on eBay (Thinkpad T60) because its BIOS was documented as being able to change the "Master HD password". However, that was a mirage - the "Master HD password" is not the ATA Master Password - it's only a password that allows you to disable the ATA User password.

Seagate Secure and traditional ATA password modes are mutually exclusive. One cannot activate both types of passwords at the same time."
Finally, for my FDE drive, there is no other way to manage security other than with ATA passwords. The ST9320329AS comes with no Seagate Secure (AKA Drive Trust) features, which I didn't want. See:
http://www.seagate.com/docs/pdf/datasheet/disc/ds_momentus_5400_fde_3.pdf
So for my FDE drive, security has everything to do with ATA passwords.
