I have noticed that calibre takes much longer to eject the KT than you would expect. Is it possible that you pulled it out before it had finished and it has somehow got corrupted?

The USB Connect icon disappears straight away, but there is no disconnect sound until I eventually remove the USB cable.
I might try deleting the driver and trying again.....
