title: DriveInfo.GetDrives show not connected network drives
body: <p>Is it possible to obtain all drives? For example, the network drives are not connected due to lack of authentication.</p>
  
  <p>I see in my explorer, e.g. the letter <em>Z</em> with a red cross. 
  This connection is stored without authentication, but this code does not give me this letter.</p>
  
  <pre><code>System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
  </code></pre>
  
  <p>And: how can I register a listener for connection of an USB-drive?</p>
