Hi all !
I am writing disk filter driver.
I dont want to attach filter to bootable disk, I mean only the disk, from
which the system is booted now (not all the
bootable devices).
How can I recognize such a device in AddDevice() of filter?
Regards,
Dany

Look for the DO_SYSTEM_BOOT_PARTITION bit in the device object flags field.
This is set for the disk from which the OS itself is loaded. Of course,
this could be different than the disk from which the boot loader was
loaded…

Tony,
Is this flag set for disk device object or for bootable partition device
object?

There were some PnP usage notifications - “used for pagefile” or such.
Maybe they will help?

Boot device such as a mass storage device that contains the system
paging file, hibernation path, or crash dump path. The operating
system notifies the driver for such a device before it writes such
a file to the device (IRP_MN_DEVICE_USAGE_NOTIFICATION).
