Fixing USB Mounting Problems After Install

Wolfkeeper, good looking out and thanks for the heads up!

When you use a LiveUSB drive to install Ubuntu on the Dell Mini 9, you create a problem with your fstab: any USB flash drive you insert into your mini will be seen as a CD/DVD drive.

If you get this error, "invalid mount option when attempting to mount the volume", apply this very easy fix.

In a terminal type:
sudo gedit /etc/fstab

You should get a text file similar to this:
Screenshot-fstab (-etc) - gedit
Look for a line that is similar to the highlighted section.
It has my USB drive as /media/cdrom0, making it unable to mount.

If you need to see what your USB drive is being mounted under,
In a terminal type:
sudo fdisk -l
and look through the output for your device name.

Simply delete the line.
Screenshot-fstab (-etc) - gedit-1

Now you can use USB drives normally.

Have a question or problem that this article doesn't cover?
Ask our Ubuntu Mini 9 Google Group for help.

When I plug my external CD drive into the mini it works fine.
