Apologies for necroposting, but I've been looking for a similar feature and the lack of it annoyed me sufficiently that I wrote a patch to add the required functionality to hdparm. Details here: http://www.altechnative.net/?p=140 Patch here: http://sourceforge.net/support/tracker.php?aid=3276513 Hopefully it'll get accepted into hdparm, but given the amount of spam I saw on the SF forums I rather doubt anyone is paying much attention there. Maybe I should open a Fedora bugzilla ticket instead... From what I can tell from my sample set, only Seagate disks seem to have this features; none of my Hitachi, Samsung, Western Digital or Toshiba disks have it, but all of my Seagates do. HTH.

That's what I am interested in.
