+Cambiamos el fichero /etc/smartd.conf y añadimos la monitorización de los discos, por ejemplo un test Largo (L) el lunes (número 1) a las 19
+  /dev/sda -d sat -s L/../../1/19 -m correo@example.com
+Añadimos también un test corto cada dia a las 2 de la mañana y el largo lunes a las 3:
+  /dev/sda -d sat -s (S/../.././02|L/../../1/19) -m correo@example.com
+Para que se ejecute al arrancar el servidor, en el fichero /etc/default/smartmontools descomentamos la línea
+  start_smartd=yes
+Arrancamos el servicio
+<code>
+# /etc/init.d/smartd status
+/usr/sbin/smartd is not running.
+# /etc/init.d/smartd start
+Starting S.M.A.R.T. daemon: smartd.
