hdparm doesn't load hdparm.conf
I have hdparm installed. I opened /etc/hdparm.conf and uncommented some options to activate the functions as the files says. For instance I have uncommented the -B apm management option but it obviously doesn't take effect even after reboot so I have to do hdparm -B 255 /dev/sda manually. How can I make hdparm load the settings from /etc/hdparm.conf. When I installed hdparm I assumed it is automatically started by the system so I haven't made any configurations to to it apart from the hdparm.conf file.
