    Re: laptop harddrive Load_Cycle_Count issue

    Recently did a clean install of Ubuntu v9.04 (Jaunty Jackalope) and the problem has been fixed in this version. No need for me to do any of the fixes.

    Hi, I just want to confirm that I no longer need to do this with 9.04.

    Thanks, and how can I check.

    In terminal:

    sudo apt-get install smartmontools

    date; sudo smartctl -a /dev/sda | egrep '(Load_Cycle_Count|Temperature)'

    Run the second one every so often (15 minutely if you're bored, otherwise something like daily )

    Since I've installed 9.04 I've noticed that the hard drive would cycle on and off very frequently. Neither the -B 254 or -B 255 had any affect. I tried the -S 0 and I think this fixed it.

    A clean CLI only install from an alternate 9.10 CD still has the old Load_Cycle_Count problem. Solution: install acpi-support
    Code:
    sudo aptitude install --without-recommends acpi-support smartmontools
    smartmontools is probably not part of the solution, just needed to check the Load_Cycle_Count.

    Re: laptop harddrive Load_Cycle_Count issue

    After upgrading to Karmic 9.10, I noticed that my hard drive was starting and stopping a couple of times a minute. Issuing a smartctl command didn't make a difference, and neither did unchecking "Spin down hard disks when possible" in System > Preferences > Power Management.

    I tried removing the packages laptop-detect and laptop-mode-tools and rebooting. This seems to work. It also seems too simple and too easy. Where is the Linux joy in tinkering with arcane scripts I don't understand? Still, it seems to work. Something in the scripts must have interfered with my laptop's default tendency to keep the hard drive spinning.

    This could possibly be a problem under battery power, if changing the Power Management settings for battery power has no effect. But I never unplug my laptop anyway.

    This works for me on my NC10 using Xubuntu (Karmic.) Having thought I had found a solution I tried a fresh install of Linux Mint 8 hoping that it work there too. It doesn't. I am going to return to Xubuntu. Though I am only a light user and it would be years until I hit my drive's maximum duty cycle I find the noise (and knowledge of what is happening to small parts under great load) disturbing. I see a copy of Windows 7 in my not to distant future............

    EDIT: I am correct in thinking Debian has fixed the problem? Or I am getting confused with all the messing about?

    I hear the clicking of the HD on my HP mini 5101 running UNR 9.10 when on battery. 2 days of use and a load cycle count of 978 (scary, isn't it?). The only fix that has worked for me is setting the apm to 254 after every boot.

    That's the default and expected behavior. The head parking was designed to save energy and to protect the disk in case of a strong jolt.

    Have you tried to going to Power Preferences and uncheck the box that says "Spin Down Hard Disks When Possible"?
