It's a new XP installation, runs pretty smoothly.
I've noticed, an hour ago, that the HD light is constantly on, it's not even flickering. Touched the box - there really seems to be constant HD activity. I ain't running anything that's supposed to cause this (like a scan or a defrag). What could it be? How can I monitor disk activity and, more importantly, which programs generate the disk IO on Windoze?
