I need to figure this out - I used to have Dropbox installed on this 8TB external drive (I moved it to an internal a week ago, but had to revert back). When I go to move the folder back, none of my other drives show up.
Additionally, I went ahead and uninstalled Dropbox, detached everything with a Dropbox folder on it, and plugged my external in. I can't choose any drive other than my main C: - nothing else shows up in the window that lets you pick where the folder will go. I have no idea what to do.
