How can I find out what is using the hard disk? [duplicate]

How can I find out what is using the hard disk? [duplicate] Once or twice a day my computer starts writing significantly hard to the hard drive, the HD led is ON and the performance hit is noticeable. A strange observation is that the Task Viewer does not show I/O activity - even Process Explorer shows no CPU activity and no I/O bytes read or written.

"I agree that Process Monitor is far too bulky and burdensome both in usage and resources.

Since you are running Windows XP, you can still use FileMon. However, you’ll have to find a copy since Mark pulled it once he released ProcMon (even though RegMon/FileMon are much faster and easier to use).

For an even lower-level view, you can use DiskMon, though it does not show process information."
