I have a lower filter driver(sits below file system driver)
From the application I pass IOCTL_DISK_GET_DRIVE_LAYOUT ioctl.
I get error as my partition style is GPT.
I am not supporting GPT Partition style for now in my driver.so I wanted to
log the error in system logs from the driver if it is GPT.
But when I tried to log it I see that the particularIOCTL never reaches my
driver.
Is it possible that file system driver can return error for this IOCTL.
I tried checking with irp tracker .when I select my driver and see for the
occurence of the particular IOCTL I am not seeing the IOCTL.
when I select the corresponding GPT disk in select disk menu I see the IOCTL
that is required.
Is it that the IOCTL is returned back with error code by file system driver
before even my filter receives it.
I also see that the error code is INVALID_DEVICE_REQUEST in IRP Tracker.
I believed that disk.sys is responsible for the above IOCTL.so I expected my
that IOCTL_DISK_GET_DRIVE_LAYOUT should reach my driver.But I am not sure
whether my driver receives the IOCTL.
Can anybody help on this.
does file system driver have any specific check in it.

Try IOCTL_DISK_GET_DRIVE_LAYOUT_EX
