3.5.4 DriveLock
DriveLock is an industry-standard security feature that prevents unauthorized access to the data
on ATA hard drives. DriveLock has been implemented as an extension to Computer Setup. It is
only available when hard drives that support the ATA Security command set are detected.
DriveLock is intended for HP customers for whom data security is the paramount concern. For
such customers, the cost of the hard drive and the loss of the data stored on it is inconsequential
when compared with the damage that could result from unauthorized access to its contents. In
order to balance this level of security with the practical need to accommodate a forgotten
password, the HP implementation of DriveLock employs a two-password security scheme. One
password is intended to be set and used by a system administrator while the other is typically set
and used by the end-user. There is no “back-door” that can be used to unlock the drive if both
passwords are lost. Therefore, DriveLock is most safely used when the data contained on the
hard drive is replicated on a corporate information system or is regularly backed up.
In the event that both DriveLock passwords are lost, the hard drive is rendered unusable. For
users who do not fit the previously defined customer profile, this may be an unacceptable risk.
For users who do fit the customer profile, it may be a tolerable risk given the nature of the data
stored on the hard drive.
