Bonsoir,
Un peu hors topic...
Je dois essayer de récupérer les données d'un disque dur :
- Win XP
- partition ... euh... FAT32 ou NTFS... je n'en sais rien... (c'est bien
parti hein)
- le PC ne boot plus, et message d'erreur de lecture immédiatement lors de
la tentative de boot.
Depuis le CDRom Ubuntu 7.10 :
ubuntu at ubuntu:~$ sudo fdisk -l
Incapable de lire /dev/hda
-------------------------
ubuntu at ubuntu:~$ sudo smartctl -a /dev/hda

sudo cfdisk
ERREUR FATALE: Ne peut lire à partir de l'unité de disque
Appuyer n'importe quelle clé pour quitter cfdisk
--------------------------------------
Je ne vois rien de précis dans ce Smartctl ...
quelques erreurs oui, mais j'ai déjà vu pire...
En attendant, je ne sais même pas lire la table des partitions !
alors encore moins les données dans une partition... non ?
une idée ?
Comme faire ?
Evidemment, je veux aider cette personne
et malheureusement, elle n'a pas de backup
(ben euh... on y pense toujours après)
Je connais 2 programmes assez bon :
récup de partition :
http://www.cgsecurity.org/wiki/TestDisk
récup de données : PhotoRec
http://www.cgsecurity.org/wiki/PhotoRec_FR
Mais avant de me lancer dans cette entreprise, tout conseil est le bien
venu.
Merci d'avance
;-)
