They do not spin down after 7 seconds, they unload their heads. In any case this behavior is not expected to ever cause Current_Pending_Sectors rising (which are plain and simple unreadable sectors no matter how hard you try or how long you wait). You can disable the 7-second unload time behavior by using either "hdparm -J" or using "idle3-tools" http://idle3-tools.sourceforge.net/ (also available in Debian). I would indeed recommend doing that to reduce wear and tear on the head mechanism from constant loads/unloads; but I somewhat doubt this will make a difference in relation to your issue. -- With respect, Roman
