That's how I connected. Now that I know those names aren't defaults, I looked a little closer, and found the G: drive looks to be the SD-EXT, since it's 16GB or so, but with no volume name, it didn't look like anything was connected. It has one (empty) folder on it (LOST.DIR). I'll try renaming the 8GB and 16GB volumes and see if anything breaks. Still no idea where the "CD DRIVE F:" came from.
Aslo, it looks like I have to Eject all 3 drives when I'm through.
