associating IRP with logical or physical disk block

Hi,

My goal is to associate each IRP with the disk blocks they access (can
be logical or physical). Is there any way to determine the logical (or
physical) OS disk block that will be accessed from an IRP?

Thanks,
Nate

IoGetCurrentIrpStackLocation(Irp)->Parameters.Read.ByteOffset or
Parameters.Write.ByteOffset

Divide to the sector size.
