 +
 +En Linux, el paquete ''smartmontools'' ofrece herramientas para controlar y monitorizar dispositivos S.M.A.R.T.
 +
 +==== Comprobar si está activo SMART ====
 +
 +Si instalamos el paquete ''smartmontools'', tendremos disponible el comando ''smartctl'' con el que podremos hacer todo tipo de consultas SMART.
 +
 +Por ejemplo, para obtener información sobre el disco y saber si soporta SMART y está activo:
 +
 +<code>
 +smartctl /dev/sda
 +</code>
 +
 +Ejemplo de salida:
 +
 +<code>
 +sudo smartctl -i /dev/sda
