smartctl

El comando smartctl permite obtener información sobre el estado de nuestros discos duros, ayudando a prevenir un fallo inminente que pueda conllevar la perdida de información.

Su sintaxis es de la forma:
smartctl [opciones] [dispositivo]

Alguna de sus opciones son:

-a Imprime toda la información inteligente sobre el disco, o información TapeAlert de la unidad de cinta o cambiador.

-T permissive ignorar el fracaso (s) de comandos SMART obligatorios. Esta opción puede darse más de una vez. Cada uso adicional de esta opción hará que otro fracaso adicional para ser ignorada. Tenga en cuenta que el uso de esta opción puede llevar a mensajes como "Característica X no implementado", seguido poco después por "Error: no se puede activar la función X". En unos pocos casos, contrariamente a la mensaje final, Característica X está habilitada.

-T verypermissive equivalente a dar un gran número de opciones permissive, ignorar los fallos de cualquier número de obligatorio.
