J'ai rebooté et maintenant le gestionnaire de media fonctionne.
Maintenant, ma clef est reconnue en tant que /dev/sdc

fdisk -l /dev/sdc

Disk /dev/sdc: 1048 MB, 1048574976 bytes

This doesn't look like a partition table

Partition table entries are not in disk order

Il semble qu'il y ait 4 partitions mais inconnues et mount /dev/sdc[1-4] /mnt
renvoie toujours:

mount: special device /dev/sdc[1-4] does not exist !!!

Comprends pas ce qui cloche !

peut-être que le format est le format dit | superfloppy x il est utilisé pour les disques magnéto-optiques par exemple. Dans ce cas, le système de fichier est écrit directement au niveau disque sans partitionnement. J'ai un disque usb qui me sert à vider mes cartes mémoires compactflash qui est formaté d'origine comme ça.

on utilise l'option -I  de mkdosfs pour ce faire..
