Its amazing, looking at the time and effort you put into your blog and detailed information you provide. I'll bookmark your blog and visit it weekly for your new posts.
Its true that one could create copy of DVD using disk utility but its not true while copying a drive or volume. I used Stellar drive clone to create exact replica of Mac volume. Although disk utility can create image of drive but that is not bootable one. For that purpose, one has to rely on some third party Mac cloning application.
When I follow these instructions, the New Image button is grayed out. Everything else looks just as it does in the figure. I'm running Lion, and the disk is an audio CD that I generated myself. It is not copy protected, nor are its contents.
I tried this but the New Image Icon is gray. Won't let me do it. This is just a CD of my personal music (that I own the rights to) that I made. It's not a commercial CD?
Thanks for sharing!
