hi:
Sorry to bother you again.
Here are the codes from R. Nagar’s sfilter(in function SFilterFSControl()).
PtrTargetDeviceObject = PtrDeviceExtension->TargetDeviceObject;
…
…
RC = IoCallDriver(PtrTargetDeviceObject, Irp);
The returned RC is STATUS_UNRECOGNIZED_VOLUME.I’m puzzled about it.Could u tell me the reason?
Thanks a lot.
Jim
