Par défaut un disque dur neuf est toujours formaté en FAT32 ou NTFS. Pourquoi vouloir passer par le Terminal ? Il suffit de lancer Utilitaire de disque, de sélectionner la racine du nouveau disque (1 encadré en rouge) de faire un clic sur Effacer, de sélectionner Table de partition GUID et selon le cas le format Mac OS étendu (journalisé) ou APFS et un clic sur Effacer.Je viens de lire les différentes réponses à la même question globale (dans mon cas : "DDE – tout neuf – pas lisible sur cet ordinateur" qui ne monte pas sur le bureau)
