This video tutorial demonstrates how to format an external hard drive using Mac OS X.10.7. Regardless of brand or model, the very first thing that you must do when you buy a brand new external hard drive is to format it properly for your system. Format your new disk immediately, before you start using it for backup or for additional file storage.

It is essential that you do take these steps right away, before you start using the drive, because the formatting process erases everything on the external disk. For more on hard drive setup see thelightroomlab.com/2009/01/formatting-an-external-hard-drive/
