Why does my Hard Drive Activity Light Constantly Blink

matter of fact you can turn off indexing itself and that will help a lot

You wouldn't think a newly installed OS would be fragmented. I'll give that a try.

you said you upgraded and if the Vista was not defragged before the upgrade now it's a mess in there yes always defrag after

Interesting. I actually upgraded from XP to Windows 7 and did a clean install.

I have the same problem on several computers, and some computers that don't have the problem. There are thousands of users who have this problem (ask Google) and no one has been able to provide a valid answer.

It is not indexing, it is not internet, it is not "how Windows is supposed to work", it is not USB, it is not DVD drive. It is not likely HDD as it occurs with both WD and Seagate drives. I haven't ruled out BIOS as all my computers use Award. Black tape over the light is not a valid answer.

I am trying to get around to asking Fred Langa if he has any idea what causes this blinking.

A certain amount of blinking is not abnormal there are a lot of things going on behind the scenes so to speak but heavy constant hard drive use can be an issue.

If you want to know what it is doing, just use the resource monitor / disk activity (type: Resource in the start menu)

I have used the Resource Monitor but I can not determine what activity is abnormal. Page File and a couple of other processes are the highest (I mention them in my first post) but how do you determine if they are using the disk more than they should?
