hi, here is my issue, i used Bios and HDD passwords, (OS ubuntu 14.4). today when i turned on my laptop and tryed to enter passwords, laptop has electrical key sounds. Bios pass worked correctly but HDD pass does not. then i somehow turned the key sound off, and turned of Bios and system passwords but HDD pasword still does not working and not appear in setup menu to resset or turn off. i rememeber my password it was same on both bios and hdd. setup menu>security indicates HDD drive as "PASSWORD SET" but has no button to turn off or reset. i dont know is it a system problem or Phisical. pls help me.
