J'ai un disque dur externe Toshiba MQ01ABD100 1TB HDD dans un boîtier externe. Depuis peu, il n'est soudainement plus accessible. Lorsqu'il est branché sur un Mac, le message "Le disque que vous avez inséré n'est pas lisible par cet ordinateur" apparaît avec 3 options : Initialiser..., Ignorer et Éjecter. Je voudrais récupérer les données sur ce disque dur externe car j'y ai copié des fichiers de travail comme sauvegarde avant de refaire mon Macbook. J'utilise l'iMac au travail pour poster ce message et je ferai le travail de récupération ici aussi.
Voici les résultats de certaines des commandes que j'ai vu exécuter dans d'autres sujets...

J'ai essayé de lire d'autres messages qui sont apparus sur Google en utilisant les messages d'erreur et il semble qu'il y ait une corruption de la table de partition ? J'espère que quelqu'un pourra me conseiller et me guider dans ce processus. C'est très frustrant car je n'ai pas l'impression de pouvoir trouver quelque chose de similaire à ce problème.
