Finder does not show external hard drive
My two external hard drives are not displayed on my desktop or in my finder after I plug them in. Time machine still backs up to it and when I run the disk utility, I see them. But that is the only area I can eject or access them. When I open in finder, I don't see them (and the option is checked to show any hard drive). It is getting frustrated since every time I want to eject them or access them I have to run the disk utility. My Imovie also recognizes the external hard drive, I can access my events. So it is kind of a weird situation. Any help will be appreciated.
