As I search further, and try to pin point exact matching symptoms of others in various forums, I start to doubt the answer to this question could fix my problem. Though I'd still love to try quitting my Finder when my USB hdd seems to be unmounted. Google should be able to tell me how to do that in Mountain Lion.
I may need to just reformat the external drive and see if that helps, as my symptoms no longer appear pandemic.
