Disques durs internes ne fonctionnent pas

#1 Post by sparetacus »

Bonjour
Je vous remercie de votre accueil et je vais décrire mes préoccupations simplement. L'ordinateur de mon fils ne fonctionnait plus. Il est équipé de deux disques durs internes branchés chacun sur une connexion SATA. Les HDD sont: HDD1-WD de 500G et HDD2-Seagate de 500G. En premier dépannage j'ai remplacé la pile bouton usagée et l’ordinateur a redémarré. Mais l'écran a indiqué de presser une touche car il ne pouvait pas démarrer (désolé je ne me souviens pas du texte en anglais). J'ai alors utilisé la touche F8 pour sélectionner le disque. Mais des messages d'erreur sont apparus : pour HDD1 "reboot et select proper boot device ... " et HDD2 "BootMGR absent ctrl+alt+suppr pour redémarrer". j'ai alors utilisé un disque de réparation w7 pour tenter d’accéder aux HDD. A partir du CD de réparation j'ai choisi l'invite DOS et j'ai identifié les disques C: et D:. Ensuite j'ai tenté de lance un CHKDSK/F et l'utilitaire a indiqué des erreurs en mettant un temps très long pour fonctionner. CHKDSK interminable pour HDD1 et bloqué à 63% pour HDD 2

Ensuite j'ai utilisé une version dos de testdisk que je lance à partir d'une clé USB bootable.
voici le log
J'ai constaté qu'au bout d'une heure de fonctionnement les disques tournaient normalement mais après redémarrage du PC HDD2 n'était plus reconnu par F8 ou testdisk.
Je vous suis reconnaissant de m'avoir lu et je reste à votre disposition pour plus d'éléments d'information. Merci de vos conseils

The log indique de nombreuses erreurs CRC/secteurs défectueux. Il faudrait cloner le disque avec ddrescue vers un disque vierge comme indiqué sur https://www.cgsecurity.org/testdisk.pdf

bonjour et merci pour ce conseil. Je vais tenter le clonage dès que je dispose d'un HDD de taille adaptée.
