Hi All,

Not suer if volume management control codes are supported in DDK or not.
I'm doing IoBuildDeviceIoControlRequest with FSCTL_LOCK_VOLUME control
code and then got the returned value 0xc00000bb from IoCallDriver.

irp = IoBuildDeviceIoControlRequest(
FSCTL_LOCK_VOLUME,
deviceObj,
NULL,
0,
NULL,
0,
FALSE,
&event,
&ioStatus);

ntStatus = IoCallDriver(deviceObj, irp);

If the volume control codes are not supported in the DDK, is there any
way to lock and unlock volume with the similar implementation
(IoBuildDeviceIoControlRequest/IoCallDriver)? Or any suggestion?

Liangyao

Yes, lock usually fails, especially if this is the SystemRoot volume =
(can never be locked).

Lock fails if there is even 1 open file on the volume.
