iMac Disque dur bientôt mort ?

[beegeezzz]

Bonjour,

J'ai formaté mon iMac de 2012, mais avant, j'avais lancé driveDX afin de vérifier l'état du disque.

Voici une capture d'écran de driveDX montrant qu'il y a un problème : voir fichier transféré au format jpeg.

J'ai également enregistré le rapport de driveDX, sauriez-vous y jeter un coup d’œil svp :

Salut

Rien de bien grave semble-t-il.
Tu peux forcer l'écriture de zéros sur le disque au cas où il repèrerai des secteurs HS :
depuis le terminal :
diskutil zerodisk force diskX
et ensuite
diskutil erasedisk jhfs+ "Macintosh HD" diskX

Il faut connaitre l'identifiant du disque. Un
diskutil list
nous en dira un peu +

Salut Jean,
Merci pour ta réponse rapide.

C'est quoi exactement le problème ? des secteurs défectueux ?

Voici plus d'informations sur le disque :

Je n'ai pas trop confiance à ces applications.
Donne les retours depuis le terminal de la commande :
diskutil list

diskutil zerodisk force diskX
…

Décidément ce diskutil révèle bien des surprises.
Je ne savais pas qu'il savait faire çà !

J'avais parcouru le "man" mais ça n'était pas ressorti de manière évidente en live.
A lire à tête reposée pour ceux que ça intéresse : https://ss64.com/osx/diskutil.html
