on 2/27/2009 Hey Jason:

Please advise those of us who have NOT watched the chapter on “mounting from fire wire external drive” what to do? Under the assumption that your viewers watched that particular chapter – you launched into a very fast and confusing explanation, of which I understood zero. If I spoke and understood your technical lingo - I would not have needed instructions on how to create a Mac start-up disc! What is the point of a VIDEO tutorial if all we see is your bearded face and/or tiny computer screen with blurred images, which nobody can read nor recognize? All spiced up with your fast presentation, references to previous tutorials and expressions that viewers do not understand! Did we see clearly what you were clicking? Did it correspond to what you were saying? Did you put the actual CD/DVD into its drive and take out a finished product? Thanks for nothing! So much for a genius!

"Hi I'm Jason previous Mac genius, and today we're going to talk about a disk image. And this is going to be a disk image, it's bootable from CD. So what we're going to do is if you've watched the chapter on mounting from fire wire external drive, using fire wire target disk mode. We've got that set up here I have the laptop in target disk mode, and I started up by holding down my T key on the computer, and then a fire wire cable plugs into the other laptop so I can access my mac book from that laptop. And so here we have mounted the mac book. And what I'm going to do to create this disk image, is go into disk utility, and I'm going to click on mac book, new image. And it's going to give us image format here for read only, compressed, read or write, or CD or DVD master. And I'm going to start off with CD or DVD master, and we're going to save this on the desktop. And I'm going to hit save. And what it's doing now is reading this whole image as a CD or master. So you would then take this file and burn it to a CD when you're done, and that should allow you to start up from that disk. I'm going to cancel that, go back in here, new image, read and write, save. And you're going to see this file saving as a disk image, so we can actually mount this file on the desktop. And then it would uncollapse when we double clicked on it and mount it as an external disk. But it would be on your system hard drive. So those are two ways you can create images to back things up or to create boot disks."
