Ma clé USB est maintenant en Lecture Seule !

When you attach your USB (read-only) key to your laptop:

• run sudo su (so that you won’t type your password all the time)
• run df -Th(to see where your USB stick is mounted)
• unmount your USB stick
• run dosfsck on the device you saw from your previous command. Example: dosfsck dosfsck /dev/sdc1
