Ok, I was totaly wrong, my own bash script used the hddtemp (frontend) 
command, while accessing directly to the server for the readings means 
no hdparm -S command working. It seems it keeps using the drives 
preventing them from sleeping. As I kill the scrip everything is working 
again. However I can't understand why it is different using the hddtemp 
command rather than accessing the server.
It is not really a collectd problem but maybe there's a way to find a 
solution.
