New Build HDD Problem

[supra21]

I have a WD Caviar SE16 320GB SATA-II HDD and a Asus P5e Mobo with Vista Ultimate and 4Gb of RAM. The problem is the HDD activity LED it stays solid and flashes constantly even when i am not doing anything on my PC, its not just the LED; from time to time i can hear my HDD processing somthing even when i am doing nothing
Ive tried the following:

- looked in the task manager for any programs using the cpu nothing, colsed all programs to be sure and the HDD LED is still flashing.

- disconnected my SATA DVD drive, still no change

- defragmenting the HDD, still no difference

Any help would be greatly appreciated!

ok well thats werid after watching the performance monitor for a while the hdd led is not constantly solid anymore but still flashes a litte every few seconds. However i can see that it is constantly writing log files, NTFS volume log?

EDIT, after looking at the performance moniter the problem seems to be solved, still flashs a bit but i cannot hear the HDD anymore which makes the system much quiter, thanks rpstewart!
