Subject: Re: Western Digital GreenPower drives and Linux

on a second system , my wd drive shows this values:

  9 Power_On_Hours          0x0032   099   099   000    Old_age   Always       -       853
193 Load_Cycle_Count        0x0032   170   170   000    Old_age   Always       -       90960

absolutely scary.....

meanwhile, i got wdidle3 from WD support and set it to 25secs (factory support seems to be at 8 secs) - but still waiting for an answer if this is a bug or not. 

i`m really wondering why support is so quiet here....
anybody got a response from support about this? 

will take a look how the drive behaves with windows......maybe things look different there.

:) I am not so enthusiastic about fiddling with my NAS box every couple of 
months.

I have suggested exactly what you say - unfortunately the conversation has 
gone cold since. Maybe they are busy already. :)
