Partition sector doesn't have the endmark 0xAA55

#1 Post by Letoine »

Bonjour,
ma belle-sœur me sollicite pour un problème critique sur une de ses cartes CF qui est passée en RAW, elle a son travail dessus qu'elle doit rendre en fin de semaine...(des photos...).
J'ai tenté une analyse rapide et "deep" avec testdisk mais il ne voit rien du tout et m'affiche seulement le message en objet : Partition sector doesn't have the endmark 0xAA55.
J'ai bien vu un bout de post sur ce sujet mais je n'ai pas l'option MFT ou alors (possible) je ne sais pas me servir de cet outil...
J'apprécierai toute(s) aide(s) pour l'aider :), un grand merci par avance,
Antoine

Est-ce que vous avez choisi EFI GPT comme système de partition?
J'assume que c'est plutôt MBR.

Essayez Photorec au lieu de Testdisk.
Si Photorec ne vous donne pas de résultats adressez-vous à un service professional.

Bonjour,

oui j'ai pris EFI / GPT, très bien le lance un Photorec en espérant des résultats car après avoir regardé et consulté des pro le prix ne sera pas abordable pour nous... tanpis

merci de votre aide,
