Realtime Disk Access monitoring?
« on: December 09, 2007, 06:53:30 PM »
Is there a program which will tell you what program is accessing a hard disk at any given time and what the program is accessing? I am trying to troubleshoot the constant churn of my hard drives and want to find out what is causing this.

yep http://process explo...er from sysinternals. On the top right graph on the main screen in my configuration it tells you the process that's causing the disk activity.

Is there anything with more detail? The windows performance snap-in is far too complex for my needs.

DTaskManager (scroll down the page to find out about the program) - Small and Portable, works on Windows 2000/XP/VISTA.

As justice mentioned, Process Explorer is excellent if you want to see the total reads/writes of an app in one place (I/O Read Bytes & I/O Write Bytes columns)... ideal for identifying _what's_ chugging your disks.

If you need a more detailed breakup Filemon would be the obvious choice. Lastly, if you find Filemon's output too detailed/overwhelming (you can filter items to make things sane, of course) you may want to look at FileTracer's "Monitor File Activity" window.

Process Monitor is the update of Filemon, and it is *much* better. Most importantly, it has great post-capture analysis. You can filter by application then sort by file and access type; this is great for beta testing apps...

Process Monitor is nice, yes, but the way filters are added is a bit tedious; they need to update the dialog+controls a bit to make it friendlier :)

Agreed, PM is da bom, but sometimes all you want to do is capture file accesses or registry activity, so I still fire up FileMon and RegMon occasionally.

PM provides too much information sometimes.  And you're right, as nice as the filtering is the interface is awkward.

Although the initial filter dialog *is* quite daunting ;-) it is as fast to use as filemon's. I then use the toolbar file/reg/process toggle buttons and everything is faster from there on. PM has a much better logging engine than FM; when tracking down a huge performance regression in Opera startup using filemon, FM would simply choke to death, so someone had to binary patch it to temporarily fix it. PM easily handled the same situation without breaking into a sweat (reliability wins over simplicity)...
