to mount a thumbdrive, open bash and switch to root, in knoppix the command is
sudo su
then issue this command
cd /mnt
mkdir usbdrive
mount -t vfat /dev/sda1 /mnt/usbdrive
this will mount the thumbdrive, but you won't be able to save to the thumbdrive or anything in KDE or Gnome cause those are open under the user knoppix, but you can read from them in GNOME or KDE. if you want to write to the thumbdrive, just do it in bash, just make sure you are root... when you are finished, unmount the drive before shutdown, like this...
umount /mnt/usbdrive
and that's it...
sudo su
then issue this command
cd /mnt
mkdir usbdrive
mount -t vfat /dev/sda1 /mnt/usbdrive
