In continuation of our conversation on my unsuccessful flash from the Windows 64bit installer, I was finally able to regain access to my SD cards by using a different formatter program. I downloaded EaseUS Partition Master and after some messing around with it, I was able to reformat my SD cards. I really have no idea what happened after I flashed Emteria the first two times, but I was successful on the third try. I am beginning to suspect that I have a hardware issue with my card reader.
I have the OS running now and I am on to the next item on my wish list - installation of Google Play and related services.
