On my Debian Squeeze laptop I am unable to auto mount pen drive or external hard drive. Here is the content of my /etc/fstab
#commented following line to just support vfat
#/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto 0 0
/dev/sdb1 /media/usb0 udf,vfat user,noauto 0 0
The problem is when I plugin a USB drive I see two icons for one USB drive. One is labled usb0 and other is the actual label of the pen drive for example sandisk or kingston. I can browse files in usb0 but sandisk/kingston is not accessible. If I unmount the usb0 I can access sandisk/kingston ladled folders and they are read/writeable by a normal user.
