Whenever i burn cd's, dvd's, or anything on my computer, I save to the internal hard drive of my computer? Do any of you guys use external hard drives to save all of your work and to move your stuff from one computer to another? It seems that some do and it is kind of safe because your internal hard drive will not get broken or hacked in. Is this true? And what operating systems do you guys use for all this stuff? Thanks for any input. What hard drives do you recommend?
