Sometimes my hard drive usage is near 100%, and I have no idea what is causing it. Are there any utilities that can help diagnose excessive hard drive usage and have as intuitive of an interface as Task Manager's Processes tab, which I can sort by CPU usage?
I am aware of using procmon, of adding columns to Task Manager's Processes tab like I/O Read Bytes and I/O Write Bytes, and using Resource Monitor's Disk tab. Too often, these don't give me useful information or clearly identify a single process that is hogging the disk.
EDIT: Some of you suggested Process Explorer, but it's not very useful here. My hard drive light was almost solidly on the entire time that this graph was being produced by Process Explorer, and you can clearly see it's barely registering any activity.
