Fix 1
---------------------------------------------------
From time to time I'll get a clicking sound from my hard drive, I have identified it to be HDD head parking problem. The fix that has worked for me was the following:

Temporary solution: sudo hdparm -B 255 /dev/sda
sudo vim /etc/hdparm.conf

Unfortunately after sleep or reboot the heads parking property resets back to default. I don't want to run this command every time so I came upon a fix in ArchLinux which put a bash script in a folder that executes everything in it on awake/power on.

In Ubuntu 12.10 I placed my script in /etc/pm/power.d and /etc/pm/sleep.d
