Erreur disque dur cible avec commande dd

#1 Post by torrom » 02 May 2014, 13:51

Bonjour,
en voulant créer une clef usb bootable d'un iso (ubuntu 14.04) a l'aide de la commande dd (sudo dd bs=4M if=/home/marc/Téléchargements/ubuntu-14.04-desktop-i386.iso of=/dev/sdd && sync), je me suis lamentablement tromper sur la cible...
Le disque en question :

>Disk /dev/sdb - 164 GB / 153 GiB - Hitachi HDS721616PLA380

ne contenait qu'une seule partition ntfs sur la totalité du disque, pleine a environ 85-90%

Apercus de testdisk avant Quicksearch :

Disk /dev/sdb - 164 GB / 153 GiB - CHS 20023 255 63
Current partition structure:
Partition Start End Size in sectors

No ext2, JFS, Reiser, cramfs or XFS marker
1 P Linux 0 1 2 123 167 44 1986496
1 P Linux 0 1 2 123 167 44 1986496

Bad relative sector.
No partition is bootable


Quicksearch et Deep Search ne trouve aucune partition.

Disk /dev/sdb - 164 GB / 153 GiB - CHS 20023 255 63
Partition Start End Size in sectors


Keys A: add partition, L: load backup, Enter: to continue



Disk /dev/sdb - 164 GB / 153 GiB - CHS 20023 255 63

Partition Start End Size in sectors

No partition found or selected for recovery

>[ Quit ]
Return to main menu



Est-il possible de récupérer l’intégrité de la table de partition même si je dois me faire une raison sur les 1GO de données du début du disque ? Ou ne me reste t-il que photorec ou recuva ou autre comme solution?

Merci par avance de vos réponses.

TestDisk aurait retrouver la partition NTFS à partir de son secteur de secours (backup boot sector) vers la fin du Deep Search.
Vu que ce n'est pas le cas, dans le menu Advanced, appuies sur la touche 'a' pour ajouter manuellement une partition commençant en "0 32 33", changes le type en NTFS, choisis Boot, RebuildBS, List. Si cela marche, choisis Write, confirm puis retrouve cette partition via Analyse, Quick Search... et choisis d'écrire une table des partitions avec cette
partition NTFS.

Merci Christophe pour votre réponse rapide,

je suis arrêté après le RebuildBS, List ne produit aucune réaction...

Pouvez-vous poster le contenu du fichier testdisk.log ? Il y aura peut-être plus d'info...

Cette fois-ci ajoutez manuellement une partition NTFS commençant en 3875 115 13, réessayer un Boot, RebuildBS, List et postez le nouveau log.

Rien de concluant. Essayez PhotoRec. Activez le mode Expert dans le menu Options, lorsque PhotoRec vous le proposera, choisissez une taille de bloc/cluster de 512 octets, utilisez les valeurs par défaut sinon.
Bonne chance
