Si apareix el missatge:
In Linux, SATA disks accessed via libata are only supported by smartmontools for kernel versions 2.6.15 and above. Try an additional '-d ata' argument.
Cal posar:
$ sudo smartctl -a -d ata /dev/sda
Sinó podeu posar només:

Si directament voleu veure si el disc està ok o no:
$ sudo smartctl -a -d ata /dev/sdc | grep "overall-health" SMART overall-health self-assessment test result: PASSED
L'anterior és un exemple d'Ok. Ara un exemple de no OK:
$ sudo smartctl -a -d ata /dev/sda | grep "overall-health" SMART overall-health self-assessment test result: FAILED!
smartd és un dimoni que permet monitoritzar de forma activa discs durs (sense la necessitat d'executar manualment smartctl).
Editeu el fitxer de configuració del dimoni smart:
$ sudo joe /etc/smartd.conf
NOTA: Segurament les opcions per defecte ja us seran vàlides i no canviareu res del fitxer
Finalment cal indicar que volem que el dimoni s'executi per defecte. Editeu el fitxer /etc/default/smartmontools:
$ sudo joe /etc/default/smartmontools
I descomenteu les línies:
start_smartd=yes
i
smartd_opts="--interval=1800"
Ara apliqueu els canvis:
Podeu veure si tot vva bé al syslog:
