Moving the OneNote 2010 Notebooks

I needed to move the OneNote Notebooks file from the C drive to another drive.  In doing so, it appears that OneNote has converted all my Notebooks to Section Groups, something that I did not expect.  How do I get me original format back without having to recreate each Notebook and copy the pages from the newly created Section Groups to the new Notebooks.

I am using Notebook 2010 Version 14.0.7228.5001, 32 bit and am running Wind 10 Pro 64 bit.
