It's black-box because although they claim to use AES128, there's no reasonable way to verify it. That said, a couple things to be aware of: Other manufacturers also provide similar features, on HDDs and SSDs Some 5 years ago or so, they began to do AES encryption on the disk itself, shipping the disk encrypted and encrypting the key with your password when you set it using the ATA Security Extensions. Even swapping out the drive electronics couldn't circumvent the password, so it took advanced tools, or hacked hardware to bypass the password. In the past, it was a logical control on the physical drive.

It is possible to do a full hardware-level image of the sectors from a known set of telemetry and manually carve the file systems out, but it's a significant barrier against all but the best equipped attackers. This doesn't encrypt the data of the disk. When these are scrambled, a traditional drive controller cannot access the disk. the sectors that contain things like telemetry and bad sector mapping. These involve encrypting the low sectors of the hard disk, i.e. This is typically performed via 3rd party software, but may also be integrated into the disk hardware.Дrive locking mechanisms are (usually) a proprietary feature of certain laptops, e.g. It's a soft protection mechanism.ДЇull disk encryption is a proper security mechanism that involves actively encrypting the entire disk, and using a password or other authentication materials to decrypt the disk data on boot. The BIOS boot password is simply a logical check inside the BIOS chip, which can be bypassed by flashing the BIOS manually or replacing the chip. There are (typically) three types on on-boot authentication:
