How do I point media bay to my external hard drive?

This may be a simple/dumb question so i apologize.

I have all of my sample sounds loaded onto my external hard drive, and when I open my media bay where do i click so that I can see the sounds?

The only check boxes i have are " media " , " file system " , and “vst sounds”

[SOLVED]

In the settings unclick " managed locations only "
