Disque D: passé en RAW, disque E: non-reconnu

#1 Post by Croc » 01 Aug 2018, 21:57

Bonjour,

J'ai apporté mon PC chez un réparateur spécialisé pour diagnostiquer une panne (il s'avère que c'était la CG mais peu importe).
Je le récupère, je le démarre, et me rend compte de 2 choses :
1) Mon disque D: apparaît bien dans mon explorateur mais la popup "... doit d'abord être formaté" s'affiche lorsque je double-clique dessus.
2) Mon disque E: n’apparaît carrément pas.
La personne qui a pris en charge mon PC est bien sûr parti en vacances et ne rentre que dans un mois, je suis donc plutôt déçu.

J'ai lancé un chkdsk sur D:, il me répond :
"Le type du système de fichiers est RAW.
CHKDSK n’est pas disponible pour RAW lecteurs."

Je lance alors TestDisk. Je me rend compte que mes 3 disques sont bien listés (sda, mon SSD qui marche très bien, sdb mon disque D: et sdc mon disque E:).
J'ai lancé une analyse sur sdb et sdc, voici les logs :

Code: Select all

Je ne sais pas trop quoi faire dans le sens où j'ai peur de toucher quoi que ce soit sur mes disque (y compris physiquement), car ça désengagerait la responsabilité de la personne qui a mis mon PC dans cet état.

Qu'en pensez-vous ?
Merci

Avant le problème, est-ce que vos disques sdb et sdc n'étaient pas en raid0 ?

Pas du tout, j'avais bien 2 unités logiques distinctes.
