Some Mounting information seems missing?

[Steven Vollom]

I am starting to learn to use a terminal.  The manual said I could see 
my mounted partitions by typing mount.  I did, and partitions I expected 
to me mounted were mounted, however, sdb5 should have shown and did not.

As I recall, I cannot yet use that partition by trying to save to it, 
but I am able to enter a sub-directore that is in that partition.  So I 
am able to store data in the drive, just not in sdb5.  I would really 
like that partition to work like the other partitions that are used for 
storage.  If that is the reason sdb5 does not show up as mounted, how do 
I properly mount that partition?  TIA

I bet a lot of you who recognize my name can see improvement in my 
understanding.
