Ubuntu :: Using Terminal To Browser External HDD?

I'm running Fedora 14 but thought terminal commands are much the same through all linux OS's. I open a terminal, I type...

[mitch@mitch /]$ cd /media
[mitch@mitch media]$ ls
3c403cc9-9f0c-4035-9148-6242daf8da84 My Book
[mitch@mitch media]$ cd /media/My Book
bash: cd: /media/My: No such file or directory
[mitch@mitch media]$

So i open Partition Manager cause i remember there been another directory to it under "/dev/sdc1", Sure enough it was, So i enter.

[mitch@mitch /]$ cd /dev/sdc1
bash: cd: /dev/sdc1: Not a directory
[mitch@mitch /]$

What am i doing, Is The link between the linux file system and the external not seen as a directory so to speak if that makes any sense? There's no particular reason i NEED to do this, It's justb bugging me that i can't get into it.
