DriveLock
Ä
CAUTION: If you forget both the DriveLock user password and the
DriveLock master password, the hard drive is permanently locked and
can no longer be used.
DriveLock prevents unauthorized access to the contents of a
hard drive. After DriveLock protection is applied to a drive, a
password must be entered to access the drive. The drive must
be inserted into the notebook, not an optional docking device or
external MultiBay, in order for it to be accessed by the DriveLock
passwords.
DriveLock involves a user password and a master password:
■ A hard drive protected by DriveLock can be accessed with
either the user password or the master password.
■ You can delete a user password or master password only by
removing DriveLock protection from the drive. DriveLock
protection can be removed from the drive only with the
master password.
■ The owner of the user password should be the
day-to-day user of the protected hard drive. The owner of
the master password may be a system administrator or the
day-to-day user.
■ A user password and a master password can be the
same word.
✎
When you start the notebook from a hard drive protected with
DriveLock, and your power-on and DriveLock user password
are identical, you will be prompted to enter only a power-on
password instead of both a power-on and a DriveLock password.
