Try this script:

case "`id -u`" in
0) ;;
*) echo Only root can run this script. 1>&2; exit 1 ;;
esac

mount | sort -k3 -r | \
while read dev ON dir TYPE type etc; do
echo mount $dir -o remount
mount $dir -o remount
done

mount | sort -k1 | \
while read dev ON dir TYPE type etc; do
case "$dev" in
/dev/*) echo hdparm -f $dev
hdparm -f $dev >/dev/null ;;
esac
done
