Hard Disk Security

This feature enables the users to set, reset or disable passwords for each hard drive in Setup without rebooting. If the user enables password support, a power cycle must occur for the hard drive to lock using the new password. Both user and master password can be set independently however the drive will only lock if a user password is installed.
