Et dans options de sécurité, j'ai mis "le plus sécurisé"
Peu-être cette option qui fout la zizanie ??? .....
(je n'ai pas vu cette option dans Utilitaires de disque)
Une copie d'écran serait la bienvenue....

Si tu formates ne serait-ce qu'une de tes cartes avec un PC > et qu'elle fonctionne ensuite avec ton appareil --> il serait alors intéressant de vérifier sur ton Mac quel est ce format de volume qui est reconnu valide.
Le fait d'opter pour un effacement sécurisé lors du formatage ne joue aucun rôle concernant ton problème > sinon de ralentir l'opération.
Il faudrait aussi savoir quel est le format des fichiers que tu copies dans le volume de la carte.
