Accès disque externe usb

Bonjour,

Je n'arrive pas (plus!) à monter mon disque externe USB.

Dans la commande suivante j'ai remplacé sdaX par sda, sda1, sda2 :
# mount -t vfat -o auto,exec,defaults /dev/sdaX /mnt/removable

J'obtiens toujours :
mount: périphérique spécial /dev/sdaX n'existe pas

(Je suis en usb 1 sous Mdk10.0)
Avant (que ça ne marche plus) il me suffisait de brancher le disque et
il était automatiquement monté sous /mnt/removable.
