On Windows, they&#x27;re mounted sync by default<i>, so you can just remove them. Of course, if you do so while it&#x27;s writing, you&#x27;ll have a problem - though this was the same with floppies.<p></i> Windows used to require you to &#x27;eject&#x27; but doesn&#x27;t any more, which I think is due to the above. Please correct me if I&#x27;m wrong.
