Any ideas what makes my hdd led blink once very 1 second?

[BobMCT]

My system is on 24x7 running Win 7 Ent SP1 on an HP Pavilion machine. When the system is at idle I can watch the hdd led blink once every 1 second like clockwork (no pun intended). Wondering what might be causing this activity I used task manager to stop processes one by one to see if the activity stopped. I tried to use my intelligence to select the items to be stopped. But none of what I stopped made any difference.

Just out of curiosity I'm wondering if any Windoze gurus can speculate on what task/service is causing this?

If anyone is bored enough to enlighten me I'd be grateful.

Thanks

File indexing? That tends to happen when the machine is otherwise idle.

Hope this helps.

Good thought cmeagan656! I checked on indexing/search were both on. Turned them off and we'll see what happens.

Thanks and enjoy!

Just for grins, try changing the update speed in your task manager. It's very possible the pagefile is being read for each refresh interval.
Not to mention, no telling how often the OS thinks the pagefile gets updated from idle processes.

Dave,

I've looked through the Task Manager and cannot find where to change the speed that you refer to. I would like to try your suggestion but need advice on how to change the speed?

Thanks

In task manager, click the View menu, then Update Speed, and change to High
