Well, I've downloaded the idle3-tools-0.9.1.tgz and compiled it. The first test has shown: # ./idle3ctl -g /dev/sda Idle3 timer set to 80 (0x50) So it seems that the idle3 timer is really set to 80 which according to the info in the idle3ctl.8 it corresponds to 8 seconds! However, before I decided to disable the idle3 timer, I wanted to verify, that the problem still persists. What's strange - today no continuous loading/unloading of heads takes place. The conditions are the same as yesterday. Even yesterday I've restarted the machine (cycling the power off/on) after changes in /etc/hdparm.conf, and even with that the Load_Cycle_Count was continuosly increasing. Today it still the same, increasing by one only after power off/power on. Of course I have waited until the rkhunter and updatedb finched their work (as they kept the disk active). So finally I'm giving up. I set the idle3 timer to disabled in the WD drive. Switch the machine off and on (as described here: http://mybookworld.wikidot.com/forum/t-351295/the-s-m-a-r-t-attribute-193-load-unload-counter-keeps-increa it is necessary to switch the machine off and on to really disable the idle3 timer after idle3ctl is used). I also have the following added at the end of /etc/hdparm.conf: /dev/sda { apm = 255 apm_battery = 255 } I hope it will allow my disks to survive next few years (curent count is: 282588 L_C_C after 3580 Power_on_hours and 1686 Power_on_Counts in Seagate ST9500420AS, and 97309 L_C_C after 1481 Power_on_hours and 692 Power_on_Counts in Western Digital WDC WD7500BPKT-75PK4T0 Thanks a lot for all suggestions!
