This question already has an answer here:
I recently purchased a 1 TB Seagate ST31000528AS drive and I have Windows 7 RC (build 7100 installed on it). I've noticed that whenever the computer is idling, the hard drive light tends to blink at a rate of about once per second. What are the possible reasons for this?
As far as I can tell there should be no disk activity (all non-essential services are switched off and if there's some amount of swapping going on, then I would assume the drive activity would be a little more erratic that that.
At the same time I've installed drive activity monitoring software but it doesn't blink at the rate of 1 per second. So I'm inclined to believe that there's really no read-write activity taking place.
Bottom line..what's with the blinking lights?
