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

[SirLancelot]

For me best solution in Hardy was:

Put:

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


In:

/home/[User_name]


And next:

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/


It was only way to hold load/unload hard drive cycles.

Any other methods discribed in:
https://wiki.ubuntu.com/PowerManagement

Failed.

But in Ubuntu 8.10 there are no good method for me to stop load/unload hard
drive cycles when I switch off AC cable and work my MSI VR610 Laptop on
Battery.

In the same configuration I had under Ubuntu 8.04 with no load cycles except
TurnOff... Now under Ubuntu 8.10 I have 6 load cycles per minute! It's too
much in my opinion.

Please describe good method to slow down cycles under Ubuntu 8.10!
