preventing partmgr from loading for a disk;

[krish]

How can I prevent partmgr from loading for my disk. I have an disk
upper filter driver below partmgr. I want my disk device stack to be
upto my filter driver - partmgr (or any driver above partmgr) should
not get loaded for my device stack. Is there a way I can achieve
this.

I tried intercepting IRP_MN_QUERY_ID in my disk upper filter driver
but looks like this IRP is sent even before my filter driver gets
loaded (I think during enumeration of partition PDOs). Please help.
Thanks.

Change the DeviceType in IoCreateDevice to something other than
FILE_DEVICE_DISK.

Hi Don, I already tried that by setting it to FILE_DEVICE_UNKNOWN but
seems like the partitions gets enumerated before filter driver's
AddDevice is called and no matter what I do in my filter driver
partmgr gets attached. In fact the disk device appears in disk
management too which is kind of unexpected after setting
FILE_DEVICE_UNKNOWN.

Any more ideas? Thanks a lot.
