You need to configure it in your auto.* files.. etc. And make sure autofs is installed and or running.
Sorry, I'm newbie, so if you can write me what exactly I must do...
I do this :
mount -t vfat /dev/sd0 /mnt/pen
I see now my pen, but cannot read it with KDiskFree because isn't present in fstab.
is this command right ?
