That's why it won't let you see it - the icon you clicked corresponds to
the part of the disk currently mounted at /. So when you list the files
at / you are looking at that drive.

No, that won't work - "/" is a very specific directory, it's the start
of the entire filesystem. You can't go and look at the "/" directory of
a drive because there's no such thing, it only applies to the start
directory of the filesystem on a running machine. Perhaps you are
getting confused with that bizarre system Windows uses of a "C:/"

Step 1 is to get more educated on how the Linux filesystem. Somewhere in
the Ubuntu docs there is a document that describes it - it's in the
menus. Go find it and read :-)

The gist of it is that you have to find out what Linux calls the device
you want to access. Some more questions I need answers for:

Did you fdisk/create a filesystem/format the new drive?
In a terminal, run these commands and post the output they give:

sudo fdisk -l
sudo df -h
sudo mount

When it asks for a password, supply your own password.
