Windows 7: What's causing heavy disk activity on USB drive?

What's causing heavy disk activity on USB drive?

I'm not sure if this was happening before, but today I noticed that when the system is in its monitor off mode (I have it set to go after 20 minutes of non-use) the activity light on my USB drive will be blinking like crazy. Moments after I move the mouse to get back into working mode it will stop. Didn't do this with XP Pro. Ideas?

No, it's not. I checked the Power Options and USB Selective Suspend was Enabled. I set it to Disabled and will see what happens when it goes back into monitor off mode.

...well that did nothing. I wonder what's making this happen?
