18.104.22.168.2 Sending a Client Drive Device List Remove Message
The client MAY send this packet at any time after receiving the Server Device Announce Response message for the specified file system. Any requests to that device after sending this message MUST be considered invalid and the request will be discarded.<14>
Note The client MUST send the DR_DEVICELIST_REMOVE message for devices that are removed after a session is connected. The server can accept the DR_DEVICE_REMOVE message for any removed device, including file system and port devices. The server MUST also accept reused DeviceIds of devices that have been removed, providing the implementation uses the DR_DEVICE_REMOVE message to do so.
