First of all, as far as the sdcard is concerned. sync has nothing to do with it, UNLESS, you are trying to remount the same exact sdcard.
sync is not infallible, and as such will not always do what you think it may do. sync can take a considerable amount of time to achieve what you think it should achieve. What does a UI(Unity ) have to do with DD ? An application that has been around for YEARS longer than Unity ? All you can do is: write data remove media. sync. If the OS you're using screws this up, then it does not deserve to be used. Otherwise, it is user error.
