44  * #GDrive - this represent a piece of hardware connected to the machine.
45  * It's generally only created for removable hardware or hardware with
46  * removable media.
47  * 
48  * #GDrive is a container class for #GVolume objects that stem from
49  * the same piece of media. As such, #GDrive abstracts a drive with
50  * (or without) removable media and provides operations for querying
51  * whether media is available, determining whether media change is
52  * automatically detected and ejecting the media.
53  * 
54  * If the #GDrive reports that media isn't automatically detected, one
55  * can poll for media; typically one should not do this periodically
56  * as a poll for media operation is potententially expensive and may
57  * spin up the drive creating noise.
58  * 
59  * #GDrive supports starting and stopping drives with authentication
60  * support for the former. This can be used to support a diverse set
61  * of use cases including connecting/disconnecting iSCSI devices,
62  * powering down external disk enclosures and starting/stopping
63  * multi-disk devices such as RAID devices. Note that the actual
64  * semantics and side-effects of starting/stopping a #GDrive may vary
65  * according to implementation. To choose the correct verbs in e.g. a
66  * file manager, use g_drive_get_start_stop_type().
67  * 
68  * For porting from GnomeVFS note that there is no equivalent of
69  * #GDrive in that API.
