[WD20EADS] Smart: Load_Cycle_Count increases fast

Hi guys!

In my DNS-313 powered by ffp 0.5 I have successfully installed WD20EADS 2TB hdd. I wrote about it here -> http://forum.dsmg600.info/viewtopic.php?id=7435 .

Set up NFS for my wdtvlive and overall performance is OK. DNS is powering it down after 5 min in idle, as I want it to.

Now I read about eads series of wd's hdds and their 'bug' (?) in IntelliPower with linux machines which causes Load_Cycle_Count parameter to increase rapidly, about every 8th second.

So I installed smartmontools package to closely monitor smart parameters.

Here they are for a disk which is 5 days old. This param is now at 1499.

==============================

Do you think it would be wise to change this parameter with wdidle utility at for example 30sec?
The main purpose of my NAS is 80% nfs streaming, 20% backup function for the rest of the PCs...
