This command can be executed only when the drive is in unlocked mode. When the drive is in locked mode, the drive rejects the command with an Aborted command error.
The SECURITY DISABLE PASSWORD command requests a transfer of a single sector of data from the host including the information specified in the following table. Then the drive checks the transferred password. If the user password or the Master password match the given password, the drive disables the lock function. This command does not change the Master password which may be reactivated later by setting a user password.
