No.
External, Internal, doesn't really matter.
"/dev" is for devices. These are low level things. "/dev/sdc" is just
the raw drive itself. It has no files, it has no directories, it's just
a giant bucket of bits.
A filesystem is something that gives meaning to that bucket of bits.
It may be vfat/fat32 Windows type structure, or it may be ntfs (windows
NT, and XP an later), or ext2 ("native linux").
/dev stuff is like a blank book, or a book with smears of letters. The
filesystem adds a table of contents, chapters, pages, index, etc.
The 'mount' command links a file system with a device.
So in your case, you have /dev/sdc5:
/dev/sdc5 88402 120853 260667392 83 Linux
That's a partition (a section of the hard drive) starting at block
88402, running to 120853 for a total size of 260G.
If that's the partition you want to use for music, you need to attach
it to the filesystem. That's where mount comes in.
WHERE you attach it is entirely up to you. Some places are ... odd.
'/dev' is for raw device stuff and you don't want a raw device thing.
'/etc' is used for system config stuff, and that's not right.. etc.
Logical places would be under '/home' (for where users files go) or
'/media' (since some people like that and its somewhat descriptive).
If you want, say, "/music", you will first need to create a 'mount
point' so you can put it there. Much like you shouldn't toss stuff
randomly in a file cabinet... you should make a new file folder and
toss stuff in THAT.
So: mkdir /music
Will make an empty folder to put stuff in.
chmod 755 /music
will make it it is readable
chown john /music
Will make it so that YOU own that empty folder.
Now, we don't want to copy the -contents- of the drive to that folder.
We want to take your drive and sort of fuse it into things.
So:
mount /dev/sdc5 /music
Says "take the physical bucket of bits, and make it usable as a
filesystem at /music"
In windows sense, that's "take the USB drive and attach it to F:"

Well, after more years of Unix than I like to think about, it's second
nature to me, and Windows with its drive letters confuses me.
("What the heck, I don't HAVE floppy drives, why do we start the
alphabet with C??")
That Wiki page isn't quite right for you if you're using ext2 (that
partition labelled Linux). It's mainly to get around that Linux wants
permissions and Windows usually doesn't, so it's more about "how to
fake permissions on a windows drive" than anything about USB.
