Hej igen

sandt nok - det er kun beregnet på til Debian:

## 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.

#/dev/discs/disc0/disc {
#	mult_sect_io = 16
#	write_cache = off
#	spindown_time = 240
#}

#/dev/discs/disc1/disc {
#	mult_sect_io = 32
#	spindown_time = 36
#	write_cache = off
#}

#/dev/cdroms/cdrom0 {
#	dma = on
#	interrupt_unmask = on
#	io32_support = 0
#}

#/dev/hda {
#	mult_sect_io = 32
#	write_cache = off
#	dma = on
#}

#/dev/hdc {
#	mult_sect_io = 32
#	write_cache = off
#	dma = on
#}

#command_line {
#       hdparm -q -m16 -q -W0 -q -d1 /dev/hda
#}
/dev/hdb {
	dma = on
}
/dev/hdd {
	dma = on
}

Men som du kan se har jeg ofte deaktiveret min hdparm.conf fil, og HVIS 
sudo hdparm -d1 /dev/hda slår DMA til uden problemer kan du som jeg blot
lave en lille batch-fil som blot kører denne komando. Jeg har den liggende
på min menubjælke til når jeg har brug for alvorligt arbejde.
