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.

       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.

       Please  read  /usr/share/doc/hdparm/README.Debian for notes about known
       issues, especially if you have an MD array.

       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.

       Root file systems.
              Please see README.Debian for details.  ROOTFS = /dev/hda

       You  can use straight hdparm commands in this config file as well - the
       set up is ugly, but it keeps backwards compatibility.  Additionally, it
       should   be   noted  that  any  blocks  that  begin  with  the  keyword
       ’command_line’ are not run until after the root filesystem is  mounted.
       This  is done to avoid running blocks twice.  If you need to run hdparm
       to set parameters for your root disk, please use the standard format.
