Need Disk Monitoring Utility

I am in need of a "disk monitor". I have a laptop that just beats on the hard drive to the point nothing runs. The CPU usage is fine but something is continually writing to the disk. I tried SysInternals diskmon but get and error about access denied when running it.

   Is there such a utility that will tell me what is beating up the hard drive?

Open Resource Monitor (there's a link in task manager).  That lists all the processes reading and writing to the drive.  It COULD be Windows preparing updates in the background.

I like to use ProcessHacker from SourceForge.  Here's the URL:

Running it as administrator will show the files disk activity.  I've found that it reports better, in some aspects and maybe right for you, than using resource monitor.  It's free, easy, and low overhead.
i suppose you tried task manager >  Performance>Resources, and selected the disk ?

Task Manager and Performance just shows four instances of "System" continually writing to the hard drive. That isn't quite enough to go on.
ok - post laptop model, + ram spec, + disk model, size and free space
