How to delete the volume of dynamic disk?

NTDEV
1

Hi all,
I created a virtual dynamic disk by employing a scsi miniport driver and a
private bus driver.
After I stoped my virtual disk device, I could see in WinObj that my virtual
disk device object was deleted. But the volume object relevanted to my
virtual device object still existed. Therefore, I could still see the drive
letter in explore.
My question is how to delete the volume object when I stop my virtual disk
object?
I know that Diskpart can do the job. But is there any other way of sending
some IOCTLs?
Thanks in advance.

How did you stop your virtual disk? If you want a controlled removal you
should be unmounting volumes and then removing the disk. Also if you think
your disk ought to function like removalbe media you ought to indicate that
it is removable media. The volume manager api in the platform sdk includes
interfaces for unmounting volumes.

Emulate PnP removal of the disk in your private bus driver.
