What actually is the point of the Manage Drives dialogue??! I, too, have several drives there that once detected they never go away, and clicking the Manage button just brings up a screen with blank panels in it and some buttons that pretty much do nothing. What is this dialogue for?
Hi, I think this is one of those areas which got started and never completed. Pluto has many of those too. In many ways it would be better if these were not visible in the UI until they worked... but on the other hand it would make those parts of the system more difficult for anyone wanting to modify or improve them.
