I am running Ubuntu 14.04, 64 bit, and have had essentially no issues with it thus far. However, whenever I plug in a USB flash drive or an SD card, it seems to open in Shotwell. First I went to the "System Settings" and then "Details" and tried to adjust the default actions upon removable media being inserted, as I was almost certain that those settings would be pertinent to the issue. No settings changed the issue, at all. If I right click on the Unity icon, and then click "Open" or even left click the Unity icon, it first opened in Shotwell, never Nautilus. Does anybody know what I could do to simply open removable media in nautilus once again, or at least have the option in Unity? The drives appear to be fully mounted at all times. I am able to access the drives by opening Nautilus, plugging in the removable media, and waiting for the removable media to appear in the left column, that works perfectly fine. The remaining issue is the automatic opening of Shotwell upon inserting removable media, and the lack of ability to open the device in Nautilus automatically or from Unity. All help appreciated!

I actually just fixed it. Here was my solution.
First, I edited the mimelist
sudo gedit ~/.local/share/applications/mimeapps.list
and searched for any entries that started with inode/directory= and deleted them as pursuant to doug's solution regarding "Unity links to USB drives do not open nautilus." Coincidentally, the entry linked to shotwell and looked something like
inode/directory=...shotwell;
Then, I installed Ubuntu Tweak via:
sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak
and opened Ubuntu Tweak.
Under the File Type Manager (a mime list module) I went to 'All' and looked for the file type 'Folder'. This file type was linked to Disk Usage Analyzer, so I changed that back to Nautilus and everything worked normally.
No more opening in a random application by default, and no more failing to open in nautilus when clicked from Unity. Let me know if this solution works for anyone else.
