There is no need in a service or init script, because hdparm options are handled by udev on system start. Having an init script will not help reseting any manually set options, unless these options are defined in the hdparm.conf and the default hdparm.conf comes without any special option set. > > I have looked at the man pages for hdparm and hdparm.conf and read > what's available in /usr/share/doc/hdparm.

I see, yes this is a useful feature and should be documented. As the workaround for the absent init script one can use the following command to reset settings defined in the hdparm.conf: DEVNAME=/dev/<DISK> /lib/udev/hdparm Hope this helps. Alex
