Disques durs RAID 1 en RAW

#1 Post by Stef » 25 Jul 2015, 15:15

Bonjour,

J'ai un boîtier USB avec deux disques durs en RAID 1. Tout fonctionnait normalement et un jour, celui-ci est devenu illisible dans Windows. Quand je clique dessus dans l'explorateur, une fenêtre me demande de le formater. J'ai vérifié dans la gestion des disques, le système de fichiers est maintenant en RAW.

J'ai utilisé TestDisk et réussi à accéder à mes fichiers. Maintenant qu'ils ont été sauvegardés, je voudrais essayer de réparer mes disques durs. Malheureusement, je n'arrive pas à comprendre le problème. Le fichier log indique plusieurs erreurs, que le disque dur semble trop petit et que des partitions ne peuvent pas être récupérées.

Pourriez-vous m'aider et m'indiquer la procédure à suivre ?

Merci d'avance.

Si tu as la place, tu peux utiliser testdisk pour recopier les données.
Mais sinon je pense qu'un "fsck /f d:" ou "fsck/f e:" devrait résoudre le problème.
