Bonjour,
le fichier de configuration hdparm.conf de ma machine contient la ligne
suivante :
# -B apm setting
apm = 255
Cependant, ce paramètre ne semble être pris en compte.
J'aimerais savoir si j'ai oublié quelque chose.
La pièce jointe contient la totalité du fichier "hdparm.conf".
Bien entendu je suis sous Ubuntu. Version Hoary.
Merci d'avance pour votre aide.

## 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.

## New note - 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.
#Samples follow:
#First three are good for devfs systems, fourth one for systems that do
#not use devfs. The fifth example uses straight hdparm command line
#syntax. Any of the blocks that use command line syntax must begin with
#the keyword 'command_line', and no attempt is made to validate syntax.
#It is provided for those more comfortable with hdparm syntax.
