## Detailed Description

Virtual File System drive management.

This represent a piece of hardware connected to the machine. It's generally only created for removable hardware or hardware with removable media. Gio::Drive is a container class for Gio::Volume objects that stem from the same piece of media. As such, Gio::Drive 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.

If the Gio::Drive 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.
