There are two passwords you can set, a user password and a master 
password. Since the command works with "--user-master u", this
indicates that the password you're specifying is the user password.

You must set a master password via

	hdparm --user-master m --set-security-pass <masterpassword>

and use that new password whenever you use "--user-master m".
