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

[bojo42]

HOWTO fix this problem on Ubuntu 8.10:

An up-to-date Ubuntu 8.10 (in it's default state) includes fixes for
this problem in it's "acpi-support" package. But they do not work
because there's a small failure in the scripts.

Therefore you can correct these scripts manually (just like written in
https://bugs.launchpad.net/ubuntu/+source/acpi-
support/+bug/59695/comments/612 ) or you simply install the updated
package including these fixes form Tom's PPA
http://ppa.launchpad.net/thjaeger/ubuntu/pool/main/a/acpi-support/ .

And when you want those stuff also to function at the wakeup from suspend, you should just run
sudo ln -s /etc/acpi/resume.d/90-hdparm.sh /etc/pm/sleep.d/
in a terminal next to you.

It is just as easy as this. After done that you only need to plug off
and in your AC to get the fixes working. BTW they are designed to work
exclusively at AC, as they would otherwise deactivate the shock
protection of your laptop's harddrive when running on battery.
