Persistent configuration using udev rule

To make the setting persistent, adapt the following udev rule for your values:

/etc/udev/rules.d/50-hdparm.rules

ACTION=="add", SUBSYSTEM=="block", KERNEL=="sda", RUN+="/usr/bin/hdparm -B 254 -S 0 /dev/sda"

If you have more than one hard drive you could make the rule more flexible. For example, to apply power-saving settings for all external drives (assuming there is only one internal drive, /dev/sda):

/etc/udev/rules.d/50-hdparm.rules

ACTION=="add|change", KERNEL=="sd[b-z]", ATTR{queue/rotational}=="1", RUN+="/usr/bin/hdparm -B 127 -S 12 /dev/%k"
