Disque dur qui plante

Bonjour tout le monde,

J'ai un PC sous ubuntu, dessus tourne un programme qui enregistre des images de caméras sur un disque.

Au bout d'un moment le programme plante, et je m'aperçois que je ne peux plus accéder au disque (monté dans /media) : "ls: lecture du répertoire /media/DD2Cameras/: Erreur d'entrée/sortie"

J'ai copié le dmesg, qui m'indique ceci :

Et j'ai bien l'impression que tout ca se répète en boucle ..


Un peu plus loin j'ai ce genre de choses :
