How to inform Mount Manager of a device that is removed

NTDEV
1

Hi! everyone
I am writing a class driver for removable media. The driver is not a PNP
driver. When a media is inserted into a drive, I create a device object
(type of FILE_DEVICE_DISK) and notify the Mount Manager by IO control
IOCTL_MOUNTMGR_VOLUME_ARRIVAL_NOTIFICATION. Because I delete the device
object when the media is unloaded, I need to notify the Mount Manager of the
media removal. I have looked into the DDK for an similar IO that can be used
to notify Mount Manager of the media removal event, I found nothing I can
use.
Can someone give me an idea. Thanks a lot.

Why not write a PNP driver?

This is absolutely incorrect. Look at Disk/ClassPnP source to see the
proper way of removable media handling.
