Show notes synopsis:

Home Folder:
-Most of the evidence is located in the Userʼs Home Folder
-Majority of the Preference PLists with user-specific settings are in 
 User/Library/ Preferences

LEOPARD:
-Disk Arbitration looks at devices and mounts the device and makes icon 
  to access this device available to the user
-On Boot, Disk Arbitration recognizes the internal hard drive. Recognizes
  file system. Mounts partitions on desktop.
 -In order to prevent writes, we must prevent the mount.

 -To turn off Disk Arbitration, enter Terminal and type:

sudo launchctl unload System/Library/LaunchDaemon/com.apple.diskarbitrationd.plist

-Now when you connect a disk, the disk will not mount

-To turn back on, enter Terminal and type:
sudo launchctl load System/Library/LaunchDaemons/com.apple.diskarbitrationd.plist

or Reboot system and diskarbitration will become active again

TIGER:
-Not controlled by LaunchCtl process
-Need to move the PList from one location to another

-Method:
1. Make copy of the diskarbitrationd.plist
2.Once the copy is made, use the remove command in Terminal to delete  
   the com.apple.diskarbitrationd.plist from the /etc/mach_init.d folder
3.Reboot system
4.Only OS Boot partition will mount.

To UNDO, Copy the diskarbitrationd.plist back to the /etc/mach_init.d  
   folder and reboot the system.
