Mount: Must be superuser to mount.

Perlluver: I have now entered both commands, but it didn't seem to work? Still getting the error.

Did you try what Xiong said, opening up gksudo nautilus and trying from there?

[TheFly]

Yes, then I get "Cannot mount volume. Invalid mount option when attempting to mount the volume 'My Book'"

Ok instead of trying to open that, run gksudo nautilus and then just mount /dev/hdb1. It will mount it to another location.

[TheFly]

You mean I should first type gksudo nautilus (then the root folder appears) and then do a new command in the terminal with /dev/hdb1 ?

hdb1 doesn't exist on my laptop, btw?

[TheFly]

However, "/dev/sdb1" is already mounted on /home it says, after running "mount /dev/sdb1" from root.

Also could you please post the output of

sudo fdisk -l

so that we can make sure that the other hard drive is /dev/hdb1 and not named something else.

There are 2 main users on your system - root and you.
Root owns your system. It allows you access to directories (folders) that ,if you change or delete them, will not harm your system.
For some reason your my book is owned by root.
You cannot mount it, or copy things on to it, or copy things from it, or delete things from it etc.
Typing sudo and gksudo in the terminal and then entering your password gives you temporary root powers to manipulate these directories should you need to.
You shouldn`t do this with most directories owned by root but some times stuff that you should own is owned by root, such as your My Book.

Typing sudo mount is giving you the root powers to mount that drive.

Typing sudo chown (change owner) is giving you the power to change who owns it - root can give it to you but you can`t take it from root.
So (give me powers) sudo (change the owner) chown (to me) yourusername (of this directory)'/media/My Book'

gksudo gives you root powers over guis (windows, as in pointy clicky things not microsoft)

Nautilus is a file browser, when you click on places in your menus the window opens with nautilus. gksudo nautilus opens these files as root so that you can drag, drop and delete by pointing and clicking.
When you have finished with nautilus as root you should close it straight away just in case you forget you are root and change something you shouldn`t by mistake.

All this root business may seem like a pain at times but it`s why we don`t get viruses and it keeps you from messing up your system. Most people who totally waste their system do so by becoming root - I speak from experience.

I`m sorry if I`m being too simplistic but a little understanding can help alot and this is absolute beginners.

Ok assuming your My Book is a 320gig external it`s /dev/sdc1

It seemed to be sdc1 yeah!
Thanks a lot for the explaination! Now I things are a bit clearer.
