Table de partition en erreur. (Linux / EXT3) - Disque dur - Hardware

Bonjour à tous,
 
Voila, j'ai un gros probléme avec mon disque dur "Data".
Celui-ci n'a (avais) qu'une seule partition, formater en EXT3 sur la totalité du disque donc.
 
Hors, un fdisk -l m'informe que la partition n'apparait plus dans la table de partitions du disque.
J'ai donc lancer l'utilitaire TestDisk, et générer les 2 rapports suivants (le premier en type de partition Intel, le second en type none) :

Avez vous un diagnostic ?
Il se trouve que j'ai 2 disques de même contenu étant donné que mon Data été monté sur un RAID miroir (logiciel) : sda + sdb = md0
Mais je ne pense pas que ca change quoi que ce soit au problème.
PS : j'ai déconnecter physiquement /dev/sdb.
 
Merci infiniment pour votre aide !
