Re: How do I tell where my thumb drive is mounted?
1. unplug device
2. open shell, use 'tail -f /var/log/messages'
3. re-plug device
4. watch output of 'tail ...' for something like 'sdf: sdf1'
5. assuming 'sdf1' was shown, try 'mount | grep sdf1' - if the device is mounted, it should show the corresponding line from 'mount'
if the device is not (automatically) mounted, use something like 'mkdir /mnt/usbstick ; mount /dev/sdf1 /mnt/usbstick' to mount it at /mnt/usbstick
