[Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime

[SirLancelot]

I have enabled all options that You described.

I have enabled all settings from:

https://wiki.ubuntu.com/PowerManagement

And:

#
# Idle timeout values. (hdparm -S)
# Default is 2 hours on AC (NOLM_HD_IDLE_TIMEOUT_SECONDS=7200) and 20
seconds
# for battery and for AC with laptop mode on.
#
LM_AC_HD_IDLE_TIMEOUT_SECONDS=7200
LM_BATT_HD_IDLE_TIMEOUT_SECONDS=300
NOLM_HD_IDLE_TIMEOUT_SECONDS=7200

#
# Power management for HD (hdparm -B values)
#
BATT_HD_POWERMGMT=200
LM_AC_HD_POWERMGMT=255
NOLM_AC_HD_POWERMGMT=255

And I put this script:

http://launchpadlibrarian.net/12024037/90-hdparm.sh


Into:

sudo install 90-hdparm.sh  /etc/acpi/resume.d/
sudo install 90-hdparm.sh  /etc/acpi/start.d/
sudo install 90-hdparm.sh  /etc/acpi/ac.d/
sudo install 90-hdparm.sh /etc/acpi/battery.d/


And I still got 6 load/unload hard drive cycles per minute!

It's somethin different betwean 8.10 and 8.04! Under 8.04 I had only those
scripts and load/unload was only on PowerOff.

Help!
