Thanks for your help guys.
I have another problem now.
When I tried to follow nvez's instructions, I wasn't sure what I was doing. I Went to Applications>System Tools>Terminal, and used the commands he gave. I got some error message, so I exited Terminal, and went to Root Terminal. Everything worked then. Now, when I browse to the folders where I've mounted everything, three of them give me an access denied error when I try to view them.
I'm probably using the wrong terminology for a few things becasue I'm just figuring everything out as I go, sorry.
