Problema com Pendrive no Ubuntu 10.10

[Vinicius Frutuoso]

O pendrive é reconhecido pelo lsusb

Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 014: ID 0930:6545 Toshiba Corp. Kingston DataTraveler 102 flash drive

Porém, ele não é montado automaticamente pra eu usar...

Quando eu tento montá-lo manualmente, ocorre um erro: Error mounting: mount exited with exit code 1: helper failed with:
mount: according to mtab, /dev/sda1 is already mounted on /
mount failed


Como soluciono isso??
