I'm looking for some info about the hdparm.conf file in Ubuntu (Jaunty). I have added some settings in there and would like to "run" them.

  1. How can I execute the hdparm.conf file from the command line?
  2. What start-up script in Ubuntu restores the hdparm.conf settings during boot?

These days most of the hdparm settings seem to be done by udev see /lib/udev/rules.d/85-hdparm.rules. That rule calls this script /lib/udev/hdparm which seems to read the hdparm.conf.
