How can I log my hard drive activity by program?
Solution 1
What you are looking for is Process Explorer. Go to "View" -> "Select Columns" then select the tab "Process Performance" and select what you want to know:
- I/O Delta Read - The total amount of reading operations caused by this process in real-time
- I/O Delta Read Bytes - The total amount of reading operations caused by this process in bytes in real-time
- I/O Delta Write - The total amount of writing operations caused by this process in real-time
- I/O Delta Write Bytes - The total amount of writing operations caused by this process in bytes in real-time
- I/O Delta Other - The total amount of other operations caused by this process in bytes real-time
- I/O Delta Other Bytes - The total amount of other operations caused by this process in bytes in real-time
- I/O Delta Total Bytes - The total amount of all operations (read, write, other) caused by this process in bytes in real-time
It looks something like that:
Solution 2
Process Monitor from Sysinternals will show you all of the disk I/O going on in your system. It shows a lot of info, so you'll have to mess around with the settings to get what you're looking for.
Solution 3
There's a tool called Diskmon from Microsoft that's used exactly for this purpose. I think that's what your looking for.
Solution 4
Hexagora Performance monitor gives good Graphical information

Solution 5
In the task manager processes tab, go to View -> Select columns. You can add columns for each process to show hard drive IO.

I am using Windows XP and am looking for a utility that can tell me the percentage of hard drive activity a program is using.
Basically, I'm looking for something like Task Manager and its ability to show CPU use but for hard drive activity. There are many times where my computer will be mostly idle on CPU, but because of hard drive activity, everything slows down. I'd like to see the programs causing that.
If it can be done by using something like SNMP or WMI with another program, I am also open to that. It doesn't have to be realtime as long as I can tell what is doing the most hard drive thrashing.

John T over 14 yearsThe IO Write Bytes and IO Read bytes tell you how much data the application has read/written from the hard disk in total since execution, in bytes obviously. You can enable the other columns to see the amount of reads/writes and check which one is increasing most rapidly.

Joseph over 14 yearsCan is be sorted by most rapidly increasing? The only way I can figure it out is with a few screenshots and a calculator.
-
Gábor Nádai over 14 yearsyou can use process monitor from Microsoft to find that out, sadly there isn't a program out there that combines the functionality of diskmon and process monitor together.
-
Hugh Allen over 14 yearsProcess Monitor doesn't show "disk I/O" - it shows total I/O, which includes other things besides the HDD.
-
Joe Internet over 14 yearsI think that you're thinking of Process Explorer. Process Monitor includes the functionality of the previous Filemon, which shows real-time filesystem activity.

Joseph over 14 yearsThis is EXACTLY what I was looking for. Thanks!

RomanSt over 14 yearsUnfortunately it doesn't seem to show anything done by the system, so you're likely to quite often find yourself staring at a nearly all-zeroes list in ProcExp despite your HDD thrashing like crazy. Still, a very handy tool.
-
Grumpy ol' Bear over 14 yearsUm...trashing like crazy = activity by an app except when you've a broken HDD. HDD's don't trash like crazy in "idle" mode.

Ignacio Soler Garcia over 14 yearsI have once or twice a day heavy HDD activity and ProcessExplorer does not show anything.

Synetech over 12 yearsActually there is. It’s called FileMon. You’ll have to find a copy, but it’s worth the effort.
