http://ubuntuforums.org – I am trying to mount a second HDD, but it won't let me do it. I'm not sure if it's trying to mount to the same place as the first HDD, or if it's just me being a ditz. My first HDD mounted straight away, so I'm afraid that I only know the below ways to mount a volume. This is the error message I got when I plugged it in, and when I tried right-click - Mount.
