Hard Drive Utilities DriveLock

a subsequent cold-boot sequence.
NOTE: This selection will only appear when at least one drive that supports the DriveLock feature is
attached to the system.
CAUTION: Be aware that these settings take place immediately. A save is not necessary.
CAUTION: Be sure to document the DriveLock password. Losing a DriveLock password will render a drive
permanently locked.

from the drive.
