DriveLock
DriveLock is an industry-standard security feature that prevents unauthorized access to the data on ATA
hard. 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.
Using DriveLock
When one or more hard drives that support the ATA Security command set are detected, the DriveLock
option appears under the Security menu in Computer Setup. The user is presented with options to set
the master password or to enable DriveLock. A user password must be provided in order to enable
