+/**
+ * SECTION:gdrive
+ * @short_description: Drive management
+ * @include: gio/gio.h
+ *
+ * #GDrive - this represent a piece of hardware connected to the machine.
+ * It's generally only created for removable hardware or hardware with
+ * removable media.
+ *
+ * #GDrive is a container class for #GVolume objects that stem from
+ * the same piece of media. As such, #GDrive abstracts a drive with
+ * (or without) removable media and provides operations for querying
+ * whether media is available, determining whether media change is
+ * automatically detected and ejecting the media.
+ *
+ * If the #GDrive 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.
+ *
+ * #GDrive supports starting and stopping drives with authentication
+ * support for the former. This can be used to support a diverse set
+ * of use cases including connecting/disconnecting iSCSI devices,
+ * powering down external disk enclosures and starting/stopping
+ * multi-disk devices such as RAID devices. Note that the actual
+ * semantics and side-effects of starting/stopping a #GDrive may vary
+ * according to implementation. To choose the correct verbs in e.g. a
+ * file manager, use g_drive_get_start_stop_type().
+ *
+ * For porting from GnomeVFS note that there is no equivalent of
+ * #GDrive in that API.
