Your D: drive contains a folder "System Volume Information" that you don't have the privileges to access. So you will need to either not access it, or catch the exception and handle it to your liking. Not having access to a folder is not uncommon outside of ones own PC, so you might want to think about handling that scenario in your user interface. Maybe paint the folder in grey or display a lock icon or something.

There was a trick to do it. Do Enable Sharing to this folder.

For more information id here

Or do this trick .....

 static void RecursiveGetFiles(string path)
{
    DirectoryInfo dir = new DirectoryInfo(path);
    try
    {

        foreach (FileInfo file in dir.GetFiles())
        {
            MessageBox.Show(file.FullName);
        }
    }
    catch (UnauthorizedAccessException)
    {

        Console.WriteLine("Access denied to folder: " + path);
    }

    foreach (DirectoryInfo lowerDir in dir.GetDirectories())
    {
        try
        {
            RecursiveGetFiles(lowerDir.FullName);

        }
        catch (UnauthorizedAccessException)
        {

            MessageBox.Show("Access denied to folder: " + path);
        }
    }
}

}
