SCSI Error - USB..mass storage

uso debian sarge(Testig)
kernel: 2.6.8-1-386

ao tentar montar o pendrive q comprei..

# mount /dev/sda1 /mnt/pendrive/
mount: /dev/sda1 is not a valid block device
# mount -t vfat /dev/sda1 /mnt/pendrive/
mount: /dev/sda1 is not a valid block device
#

dei uma verificada...... descobri isto:
alguem pode dar uma ajuda ??
