Bonjour a tous,
Mon disque dur WD EADS 2To en EXT4 ne fonctionne plus. Il m’est impossible de demarrer le PC si il est branche dedans.
Je l’ai donc mis en USB afin de pouvoir essayer de recuperer les fichiers qui sont dessus ou de reparer/corriger les erreurs.
Mais je ne m’y connais pas tres bien.
Voici un peu ce qu’il a dans le ventre (disque dur non monte)
- fsck /dev/sdc
fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/sdc
Could this be a zero-length partition?
- fsck.ext4 -v /dev/sdc
fsck.ext4: Attempt to read block from filesystem resulted in short read while trying to open /dev/sdc
Could this be a zero-length partition?
- fdisk -l

/dev/sdc is entire device, not just one partition!
Proceed anyway? (y,n) y

[code]e2fsck 1.41.12 (17-May-2010)
fsck.ext4: Bad magic number in super-block while trying to open /dev/sdc
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 [/code]
Idem pour les autres blocks…
- DD bien reconnu par le BIOS ainsi que par testdisk (mais je ne maitrise pas bien testdisk, je ne veux pas faire de betise, donc j’attends vos retours)
- Si j’essaye de lister les fichiers des partitions avec Testdisk, celui ci m’informe que “No file found, filesystem seems damaged.”
Je suis en train de laisser testdisk tourner pour detecter les partitions.
J’ai essaye photorec mais celui ci n’a pas pu recuperer grand chose (Pas de partition liste non plus)
Merci de votre aide !
