<a class="link" href="class-giodrive.html" title="gio.Drive"><code class="classname">gio.Drive</code></a>
- this represent a piece of hardware connected to the machine. Its generally
only created for removable hardware or hardware with removable media.
</p><p>
<a class="link" href="class-giodrive.html" title="gio.Drive"><code class="classname">gio.Drive</code></a>
is a container class for GVolume objects that stem from the same piece of media.
As such, <a class="link" href="class-giodrive.html" title="gio.Drive"><code class="classname">gio.Drive</code></a>
abstracts a drive with (or without) removable media and provides operations for
querying whether media is available, determing whether media change is automatically
detected and ejecting the media.
</p><p>
If the <a class="link" href="class-giodrive.html" title="gio.Drive"><code class="classname">gio.Drive</code></a>
reports that media isn't automatically detected, one can poll for media; typically
one should not do this periodically as a poll for media operation is potententially
expensive and may spin up the drive creating noise.
</p><p>
For porting from GnomeVFS note that there is no equivalent of
<a class="link" href="class-giodrive.html" title="gio.Drive"><code class="classname">gio.Drive</code></a>
in that API.
