Clés USB

Bonjour,

J'ai un message d'erreur lorsque je veux accéder aux clés USB:
"mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so"

Rapide coup d'oeil sur le syslog :

Cette clé marche bien sous XP, mais là, il ne lit pas la table de partition. Une idée ?

Je vous remercie.
