It seem that you have the hdparm package installed but not the hwtools
package. If you install it you can set up /etc/init.d/hwtools to
retain the hdparm settings. Like
if command -v hdparm >/dev/null 2>&1; then
hdparm -q -m32 -a266 -A1 -c3 -d1 -u1 -W0 -S242 /dev/hda
hdparm -q -m16 -a256 -A1 -c3 -d1 -u1 -W0 -S220 /dev/hdb
hdparm -q -d1 /dev/hdc
true
fi
echo " hdparm"
Hope this is what you were looking for.
