I have a laptop that, after boot up is completed, continues to do a lot
of disk activity for fifteen minutes or more. This is a laptop I will
use on a plane. I cannot have this disk activity use up battery charge.
I need to know which application(s)is/are doing the disk activity so I
can shut it down for the flight. The Task Manager displays CPU usage but
this has not been very useful in finding which process is using the disk
a lot at the moment. Is there a way to monitor in real time which
process is responsible for disk activity in the same manner that the
Task Manager displays this for CPU usage?

I still have the old FileMon that they dropped when they came out with
ProcMon. I've used it in the past, for example, to find what was
causing a lot of disk activity that turned out to be two security
programs fighting with each other (A would check a file, B would see the
read and do a check, A saw the read by B and would do another check, B
would see A's check on B's read and do another check, and on and on).
