Close all applications. Run Perfmon. Click on Disk. Click on disk
Write. If your system sits "idle" long enough you should eventually
see disk write drop off to nothing. If not, look to see what is causing
disk IO. Turning off Superfetch and indexing on your fixed disk
drive(s) kills lots of disk IO without effecting system performance.

The "hard drive light" can indicate more than just fixed disk activity.
If your case IO light keeps blinking about once a second after disk
write activity stops then there is no disk activity - the problem may be
the SATA/IDE chipset IO polling related to your CD/DVD drive. If this
is the case disconnect the SATA or IDE connection to your CD/DVD drive.
Does this reduce of eliminate "apparent" IO activity?

What is your motherboard brand/model and the SATA/IDE chipset(s) on the
motherboard?
