Security commands
Use PWD command to lock a drive with defined user password. According to ATA/ATAPI standard, you have to repower the drive to make password setting active. 

There are two commands to unlock drives: UNLOCK and DISPWD. UNLOCK just unlocks a drive till the next power cycle. To disable password you have to UNLOCK drive first, then use DISPWD command to disable the password. You have to know the password to use unlock or disable password commands. UNLOCK and DISPWD will ask you which kind of password you will enter: master or user. For example, PWD command sets USER password. 

Master password is set by manufacturer and can be used to unlock a drive.
