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
