Media Center is another culprit. I have often gotten this message.
If Windows wont eject it, I close calibre, close any calibre worker processes, and try again.
If that fails I shut down Windows and disconnect.
I have tried disconnecting first in Windows and it disconnects calibre, then reconnects the device (Sony 600) but calibre usually doesn't reconnect.
I think this is a Windows problem with too many programs trying to read media content from a device. Can't think why they don't prompt you first.
