Disque inaccessible apres connexion sous Macintosh

#1 Post by baptasn » 01 Jun 2017, 17:19

Bonjour,

j'ai connecté mon disque dur sur le portable Mac d'un ami. L'ordinateur a proposé de l'utiliser comme sauvegarde et de le formater au préalable.Mon ami a lancé la procédure et j'ai vite débrancher pour ne pas perdre mes données.

J'ai donc un disque avec 2 aprtitions ; une EFI GPT et une HFS.
Je peux récuperer les données avec photorec mais je voulais le réparer et récupérer l’accès(plus facile, question de stockage car le DD externe vaut 2 To).

Je vois le disque et son nom dans la fenetre Périphériques mais pas sur le poste de travail.
L'analyse avec Testdisk (avec les cylindres) est très longue en Mac table et en EFI GPT mais pas avec Intel.
J'ai peur de modifier la table de partition de peur de plus pouvoir récupérer les fichiers.

Merci d'avance de votre aide

Je joins des screens après avoir lancé différentes analyses.

Re: Disque inaccessible apres connexion sous Macintosh

#2 Post by cgrenier » 02 Jun 2017, 06:48

Vu que testdisk n'a pas trouvé de backup du secteur de boot NTFS ou exFAT, vous aviez peut-être une FAT32 et dans ce cas, le secteur de boot et son backup ont été écrasé par la nouvelle partition EFI.
Il faudrait essayez PhotoRec en activant le mode expert dans le menu Options et en choissant une taille de bloc de 512 octets après l'avoir lancer sur [Whole disk]

D'accord, photorec voit une partition hfs et efi.
Du coup je suis obligé de passer par là récupération de toutes les données ?
Y a t'il une façon pour que photorec renomme mieux les fichiers trouvés ? (c'est un le bazar pour tout retrier).

Cordialement

Bonjour,je voulais savoir si je devais" unformat en Fat" ?

et la recherche avec photorec va retrouver une backup du boot sector peut-être ? J'ai empêcher la recherche des gros fichiers ( films et les nombreuses images)
