Well... in fact that SMART value (load_cycle_count) is what you think: *** http://en.wikipedia.org/wiki/S.M.A.R.T. 193, C1, Load Cycle Count, Load/Unload Cycle Count (Fujitsu), Lower Count of load/unload cycles into head landing zone position.[14] The typical lifetime rating for laptop (2.5-in) hard drives is 300,000 to 600,000 load cycles.[15] Some laptop drives are programmed to unload the heads whenever there has not been any activity for about five seconds. [16] Many Linux installations write to the file system a few times a minute in the background.[17] As a result, there may be 100 or more load cycles per hour, and the load cycle rating may be exceeded in less than a year.[18] 4 04 Start/Stop Count A tally of spindle start/stop cycles. The spindle turns on, and hence the count is increased, both when the hard disk is turned on after having before been turned entirely off (disconnected from power source) and when the hard disk returns from having previously been put to sleep mode.[11] *** Good, bad...? Who knows. Nowadays every hard disk manufacturer applies different strategies within the hard disk firmware for power savings. Note that start/stop count parameter does not have a best rating value (nor lower/higher are better, is just an informative field). SMART test has to be interpreted in whole (there are values that are more important than others) but I would not care much if there is no other sign indicating that something wrong is goin to happen. But it is bad that it loads the head all the time. - Though I do not know if it worth (I think it does as my computer is on sure surface) - to tune it so that it will be flying all the time, or it is unwise? I would contact your hard disk manufacturer and ask about this value (if you provide them the full SMART test results, better). They will tell you if there is is something to worry about or if this is just the normal behaviour.

Load_Cycle_Count to stop growing.
Good day. I have some trouble with growing number of Load_Cycle_Count parameter of my HDD. And the Temperature_Celsius as well. - Shown by smartctl utility. So, my question is, How I can stop it spin down? - As I do understand, w/ the help of sdparm utility (it is SATA drive). Or may returm to the manufacturer defaults of the drive if any? - As I tried before to play w/ laptop-mode-tools package, and I did not like the results. Or where I can look for a utility that spins it down? In the BIOS I saw no option for spinning it down - so it is out of culprit list.

Thank You for Your time and answer, Camaleón: And what are those offending values? :-) I will not bring them here - so You may not say, Ah it is ok - there are even worse cases do exist! - For what is ok for one - not so for another. :) I just saw better values - and want to restore it - before my experiments w/ laptop-mode-tools.

And the Tell the HD to stop unloading its heads, and to stop spinning down (it *has* to unload heads when it will spin down). It will increase power consumption, and it will make you more vulnerable to head crashes (while unloaded, the heads are far more resistant to vibration). OTOH it will increase the HD lifetime, as loading/unloading heads slowly damage the head assembly. Usually, hdparm -B and hdparm -S can do it. The BIOS might fight against you and might set it back behind your back on reboot, suspend/resume, etc. Temperature_Celsius Get better cooling. If it is impossible, well, there is nothing you can do other than stop giving the disk so much work to do until it cools down. So, my question is, How I can stop it spin down? - As I do understand, w/ the help of sdparm utility (it is SATA drive). Use hdparm. -- One disk to rule them all, One disk to find them.
