[Bug 14862] Re: Freezing all security settings on ATA hard disks

[Phillip Susi]

Indeed, trying to do this post firmware adds no security, only
frustration.  In any case, hdparm had the ability to do this added long
ago, so this can be considered fixed.

Title:
  Freezing all security settings on ATA hard disks

Status in “hdparm” package in Ubuntu:
  Fix Released

Bug description:
  Nearly all modern ATA hard disks can be locked with a password. Usually the BIOS
  should freeze all security settings on these hard disks to prevent changing. But
  many BIOSes don't do that. Then, if you haven't set a password, it is possible
  to change the password and lock the disk. This can also happen without user
  interaction by viruses and worms. On Linux you need root rights, so the problem
  is not as big as on other systems.

  There is a patch available for hdparm which adds an option to freeze all
  security settings on a hard disk (see
  http://www.heise.de/ct/ftp/projekte/atasecurity/files/hdparm-5.9-ct.zip). For
  more information and workarounds for Windows and Mac OS X see
