end / request i / o erreur, dev sdc sector xxxx - SSD en panne?
J'utilise Ubuntu 12.04 et il semble que mon disque SSD échoue sur moi. Après une quantité de temps arbitraire, le disque imprime simplement end_request i/o error, dev sdc sector xxx lorsque j'entre une commande telle que ls ou toute autre commande. Cela peut arriver après 24 heures ou juste quelques minutes.
Tous les SMART tests (court/étendu) réussissent et il n'y a pas de secteurs réaffectés, bien que je ne sache pas si les disques SSD le gèrent comme les types magnétiques plus anciens.
Le nombre d'échecs du programme semble être le problème criant dans le journal SMART. 4745980543444 échoue? Est-ce presque 5 milliards de dollars?
Y a-t-il quelque chose que je puisse faire de manière particulièrement différente d'un lecteur de disque dur normal?

Il semble que cela soit plus susceptible d’être un firmware grossier que tout ce qui est trop grave. Voir:
Voici le gumph pertinent:
Ce lecteur peut se bloquer après 5184 heures de mise sous tension:

Vous avez franchi 5184 (récemment), cela semble donc d'autant plus pertinent.
Quoi qu'il en soit, sauvegardez et soyez prêt à sortir sur un autre disque.
