Is there a tool that will show me what applications are writing to the hard drive in real time? I'm thinking something like Task Manager but for I/O. I've got a number of background processes running, and can never tell when Visual Studio is holding everything up, or some other process is hogging the disk (especially when the processor is running at less than 20%).

ProcMon from Sysinternals/Microsoft.

FileMon is outdated, and not recommendable anymore. You will get more out of it's successor: ProcMon. In any case, that's the tool for the task. +1.

You're aware Task maanger can have columns for

  • I/O Reads
  • I/O Read bytes
  • I/O Writes
  • I/O Write bytes
  • I/O Other
  • I/O Other bytes

? That might help - see View/Select Columns

HA, you'd think I would have looked there... However, it appears to just show totals, which doesn't tell me who is hogging it right now. Still worthy of an up-vote, though.

Indeed. I usually just look at the screen to visually spot the ones that seem to be changing fast - which is a quick check but less useful if you want to log the results or something.

If you move the mouse over the I/O chart than you can see which process is doing the most I/O.
