    /// `Drive` is a container class for `Volume` objects that stem from
    /// the same piece of media. As such, `Drive` 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 `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.

    /// `Drive` supports starting and stopping drives with authentication
    /// support for the former. This can be used to support a diverse set

    /// multi-disk devices such as RAID devices. Note that the actual
