Restauration de partitions effacées par accident
Salut !
Alors voilà, je me sens bien bête...
J'ai voulu partitionner une carte SD avec fdisk. Jusque là no problemo, je sais comment faire.
...
sauf que je me suis planté de disque, j'ai créé une nouvelle table de partition vide sur mon deuxième disque dur au lieu de la-dite carte SD... 
(<<<--- les différents états par lesquels je suis passé)
hum... connaitriez-vous un moyen de restaurer les partitions svp ?
EDIT :
Je suis en train d'essayer la méthode d'écrite tout simplement ici, avec testdisk :
https://doc.ubuntu-fr.org/tutoriel/comm … partitions
... a suivre...

Re : Restauration de partitions effacées par accident
Si tu n'a fait que créer une nouvelle table de partitions, alors seul le mbr a dû être touché et testdisk devrait pouvoir retrouver les partitions sans trop de difficulté.

Re : Restauration de partitions effacées par accident
Ben testdisk a bien retrouvé les partitions, mais c'est pas mal le bordel alors pour s'y retrouver...

Re : Restauration de partitions effacées par accident
Bonjour
Je ne sais pas d'où sort ton testdisk.
il n'y a que le tout début qui ressemble à celui que je connais.
TestDisk 6.14, Data Recovery Utility, July 2013

TestDisk is free data recovery software designed to help recover lost
partitions and/or make non-booting disks bootable again when these symptoms
are caused by faulty software, certain types of viruses or human error.
It can also be used to repair some filesystem errors.
Information gathered during TestDisk use can be recorded for later
review. If you choose to create the text file, testdisk.log , it
will contain TestDisk options, technical information and various
outputs; including any folder/file names TestDisk was used to find and
list onscreen.
Use arrow keys to select, then press Enter key:
>[ Create ] Create a new log file
[ Append ] Append information to log file
[ No Log ] Don't record anything
Mille excuses .... C'est le fichier de log.
Ce qui est intéressant c'est ce qui va suivre cet écran.

Re : Restauration de partitions effacées par accident
Cela correspond à des adresses LBA suivantes:
a) 2048 - 614402047
b) 8192 - 122879
c) 122880 - 6399999
d) 614402048 - 819202047
e) 819202048 - 1646325759
la LBA est calculée par la formule
LBA = cylindre*16065 + tête*63 + secteur - 1
On voit qu'il semble y avoir des traces des deux partitionnements suivants :
partition a) + partition d) + partition e) + espace non alloué de 1646325760 à 1953536192
partition b) + partition c) + espace non alloué de 6400000 à 1953536192

Re : Restauration de partitions effacées par accident
C'est déjà pas mal comme présentation.
Tu peux faire enter pour continuer.
Tu verras l'autre grille. Je pense qu'elle va te rappeler ce que tu avais.
Dans ce cas tu pourras continuer..
Tu seras positionné par défaut sur deeper search
tu te positionneras à droite sur write.
de mémoire tu devrais avoir une demande de confirmation. Que tu devras accepter.
testdisk te dira de faire un boot pour valider la modification. C'est à faire dans la foulée.

Re : Restauration de partitions effacées par accident
Dak, je vais m'y atteler dans l'aprèm.
Petite question pour laquelle je pense déjà avoir la réponse : il y avait une partition cryptée (avec truecrypt), j'imagine que celle-ci est irrécupérable ?

Re : Restauration de partitions effacées par accident
testdisk récupère des partitions, il ne s'amuse pas à comprendre la signification logique des bits qui sont dedans.
Le cryptage est une opération logique.

Re : Restauration de partitions effacées par accident
Bon ben alors j'ai appliqué la restauration mais il semblerait que ça n'as pas fonctionné.
Je me retrouve avec effectivement 2 partitions restaurées mais sans contenu.
Bref, tant pis, je repars de zéro :-(
Merci pour votre aide :-)
