NAME

       hdparm.conf - Debian configuration file for hdparm

DESCRIPTION

       This is the default configuration for hdparm for Debian.  It is a rather simple script, so
       please follow the following guidelines :) Any line that begins with a comment is ignored -
       add as many as you like.

       Since  hdparm  doesn't use init script anymore, this configuration is mainly used by udev.
       Still one can re-apply settings from the config file by calling either

       /usr/lib/pm-utils/power.d/95hdparm-apm resume

       or by calling

       DEVNAME=/dev/<disk> /lib/udev/hdparm

       Note that an in-line comment is not supported.  If a  line  consists  of  whitespace  only
       (tabs,  spaces,  carriage  return), it will be ignored, so you can space control fields as
       you like.  ANYTHING ELSE IS PARSED!!

       This means that lines with stray characters or lines that use  non  #  comment  characters
       will  be interpreted by the initscript.  This has probably minor, but potentially serious,
       side effects for your hard drives, so please follow the guidelines.   Patches  to  improve
       flexibilty welcome.

       Note  that  if the init script causes boot problems, you can pass 'nohdparm' on the kernel
       command line, and the script will not be run.

       Setting an option outside of one of the stanzas enables it for all drives.

       If an option is listed twice, the second instance replaces the first.

       /sbin/hdparm is not run unless a block of the form:

       DEV {

       option

       option

       }

       exists.  This blocks will cause /sbin/hdparm OPTIONS DEV to be run.  Where OPTIONS is  the
       concatenation of all options previously defined outside of a block and all options defined
       with in the block.
