I have found that editing updfstab.conf.default in /etc works much
better. One does not need to keep track of which SCSI device to use
etc.

When an USB device has been added to the updfstab.conf.default file,
then on connecting the USB drive an empty directory is automatically
created in the /mnt directory. One can have distinctive names for the
various devices. I have "camera" for my digital camera and flash64 for
a 64MB USB flash pen, and flash128 for a 128MB flash disc.

To mount the actual device one only have to do
mount /mnt/<name>
i.e. for the camera
mount /mnt/camera

When the device is removed the directory in the /mnt also dissappears,
hence it is easy to check if a device is actually connected or not.

So far the only time I have had problems with this method, is when I
had more than one partition on a removable USB harddisc. If anyone
can give me a pointer on how to handle multiple partitions I would
appreciate it.
