DESCRIPTION:
This is a daemon that launches after every boot to keep you hard drive alive and thus stop its *Clunk* noises due to head parking. This issue as been reported on some Mac Mini version and eeepc.
Please read the entire article about ClunKiller and other solutions HERE
INSTALL:
Run ClunKiller package installer
Open a Terminal window and type:
sudo chown -R root:wheel /Library/StartupItems/ClunKiller
Enter your password etc.
Repair disk permissions:
If you do not repair permissions you'll probably see this kind of message into the Console, and ClunKiller will not run until a few hours after your next reboot:
Reboot
Now after reboot check if ClunKiller is working!
Enjoy!
UNINSTALL:
Go to /Library/StartupItems and delete the ClunKiller folder
CHANGELOG:
07/08/09:
Fixed: Better script that stops *Clunk* noises every 4 sec.
Version name: 1.2
20/07/09:
Fixed: Filtering enabled for Hard Drive I/O activity.
Version name: 1.1
17/07/09:
Intelligent version! ClunKiller can now detect when it is needed to wake your Hard Drive. It also uses a new command line to wake your hard drive that doesn't make any writing noise 
NOTE:
ClunKiller automaticaly detects when it needs to wake the Hard Drive to stop these *Clunk* noises, as you can see on this screenshot:
ClunKiller is also optimized to do not use a lot of CPU, as you can see on the folowing screenshot dtrace & sh do not use more than 0,5% of the CPU:
If you still hear some *Clunk* noises:
PLEASE READ THIS NEWS: ClunKiller - How does it work?
ClunKiller does not work for me, why?
You need a file called mach_kernel.ctfsys into your / directory to make dtrace working. If you do not have this file, try to ask people who have the same computer/OS/kernel that you use.
This is mine: mach_kernel.ctfsys.zip (But I think it will not work for you)
Try "mach_kernel.ctfsys dtrace" on Google.
If you have this file and you can still hear some *clunk* noises time to time, then I'm afraid to tell you that you need a better Hard Drive.
