-VERYIMPORTANT ISSUE REGARDING HARD DISK POWER MANAGEMENT CAUSING POTENTIAL PREMATURE FAILURE.

BASICALLY YOU WILL NOTICE A FREQUENT SEQUENCE OF CLICKS FROM THE HARD DISK. THIS IS APPARENTLY CAUSED BY A DESIGN FAULT BY THE DISK MANUFACTURER WHICH MAKES THE DISK PARK ITSELF EVERY 5 SECONDS OR SO.

MOST DISTRO'S SEEM TO HAVE INTEGRATED A FIX FOR THIS IN THE POWER MANAGEMENT CONFIGURATION. UBUNTU HASN'T YET (DESPITE THE FAULT BEING REPORTED OVER A YEAR AGO).

THE FIX IS SIMPLE HOWEVER

IN A TERMINAL TYPE:



sudo gedit /etc/acpi/resume.d/99-hdd-spin-fix.sh



INSERT

#!/bin/sh

hdparm -B 254 /dev/sda



SAVE IT



NOW REPEAT WITH

sudo gedit /etc/acpi/start.d/99-hdd-spin-fix.sh

AND

sudo gedit /etc/acpi/suspend.d/99-hdd-spin-fix.sh



IT DID THE TRICK FOR ME
