How to make Final Cut Pro to use my Tera bytes' HDD and not my Laptop's HDD? I want all videos to my external HDD and not my laptop's HDD and Final Cut Pro does not give this option. I am not wanting to use my MBA's free space for video editing. How can I define the location of videos in Final Cut Pro?
Change the Save to location to be your external drive.

Since 10.1 you can also create a library which can be stored externally. See:
