after backing up all your info, you insert the OS X disk, and then when the target disk screen pops up, you will look at the top of your screen at the menu bar, go to utilities and then go into format (erase). It will then format your disk and then the disk will have some prompts on screen (such as language, target drive, etc).

Takes about 30 minutes or so.
