Where to save hdparm settings?

Question

Hi,
my HDD has a default value of hdparm -B 128 which results in landing and spinning drive's head every 5 seconds.
To not have this, i want to disable power managment by using hdparm -B 255. From man hdparm I read that file /etc/hdparm.conf is sourced. But here comes the problem:
This file is not installed with hdparm package.
After creating this file, it looks like hdparm ignores it.
cat /etc/hdparm.conf
command_line {
hdparm -B 255 /dev/sda
But i still see the default value in hdparm -I /dev/sda and HDD turns off every 5 seconds.
Can anyone help me please? Should I report a bug?
By the way I added hdparm -B 255 /dev/sda to /etc/rc.local, so it is executed when booting, but the default value is back after pm-suspend.

Add a hook. It should look like this
#!/bin/bash
case $1 in
hibernate)
echo "A hook to restore hdparm value on resume"
suspend)
echo "A hook to restore hdparm settings at resume."
thaw)
hdparm -B 255 /dev/sda
resume)
hdparm -B 255 /dev/sda
*) echo "somebody is calling me totally wrong."
