Double check.
If you still have problems, I am not sure why it didn't fix with the 10.2.1 upgrade for you
I insert a blank CD, drag the files from the harddisk on the CD icon and then select "Burn CD" in the finder.
I also tried to use "disk copy" by first creating a dmg and second dragging it onto a blank CD icon to create the CD from "disk copy".
Both methods did not work for me. Does anyone know if you can select which file system the finder/burner uses? Is it ISO9660 or Iso9660Xtended (or what is it?). Can anybody recommend a shareware CD burner software, or can I use iTunes for making data CDs?
