Hi all:
An interesting bug that causes high frequency of of load/unload
cycles on some hard disk may shorten lifetime.
Brief
current behavior may lead to premature disk failure in laptops
due to excessive unnecessary drive parking. Fix will disable
disk cycling by default when on AC power, by correcting an error
in the hdparm logic of acpi-support.
Take a look at the issue in detail, bug description and the fix
https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695The key focus here should be to understand the 'hdparm' logic
that caused the bug in the first place.
thanks
Saifi.
