Parceque j’avais besoin de savoir pourquoi un de mes disques dur avait le status anormal dans mon Nas Synology, je me suis mis en quête de trouver la commande appropriée à saisir en ligne de commande en Ssh sur mon Nas, pour faire afficher les informations smart de mon disque dur.
Il s’agit donc d’utiliser la commande smartctl disponible à l’invite de commande d’un Synology. Contrairement à ce que le smartctl -h donne comme information de saisie, la saisie de :
smartctl -all
ne fonctionne pas …. 
La commande qui marche est :
smartctl -d ata /dev/sda -a pour le premier disque
smartctl -d ata /dev/sdb -a pour le suivant , etc ….
Dans mon cas , sur le disque « défectueux » , j’obtiens :
Synology> smartctl -d ata /dev/sda -a

Bon… assez indigeste…et pas toujours compréhensible… mais il est clair, que les deux lignes que j’ai mise en rouge ci-dessus ne sont pas pour me rassurer …. Si quelqu’un sait interpréter correctement ces résultats , qu’il n’hésite pas à l’indiquer !
