Well Ive got my new set of 10 DVD's and I have just tried this ..
Burning a CD or DVD .... The Finder can burn files to a CD or DVD
1. Insert a blank disc into the optical drive of your computer.
If you see a dialog, you can choose an action from the pop-up menu and select "Make this action the default" if you want the same thing to happen every time you insert a blank disc.
The disc appears on your desktop.
2. Double-click the disc to open it, and drag the files and folders you want on it to its window.
The Finder places aliases to the files in the disc's window. The original files are not moved or deleted.
3. Arrange and rename the files exactly as you want them.
When burning the disc, the Finder gives the items on the disc the same names and locations as the aliases in the disc window. After the disc is burned, you cannot change them.
4. Choose File > Burn Disc, and follow the instructions.
The files that the aliases point to are burned to the disc. In addition, if any folder you copied contains aliases, the original files for those aliases are burned to the disc as well.
I was hoping that I could just keep feeding in a new DVD each time until all the info was completely transferd from my external HDD to the set of DVD's,
but when I inserted the first blank DVD , I got this warning box on screen , Is there any way I could set up some thing so when the first DVD is full I get a warning on screen to tell me to eject the full DVD and insert a new blank DVD, until all the information is completly transfered to the set of blank DVD's ? , I do not know just how many files to remove that would fit on one DVD, so the above would help
