I have a friend who burned a CD with a Roxio Easy CD Creator on his windows machine, and he says that he has used a sort of windows multiple burn technology...the ability to burn 1 CDR more than once by progressively filling the CD up. Can I do this on my Mac (finish filling up a CD he has partially burned already on his Windows machine), and how can I get my Mac to recognize the CD he has partially burned? It doesn't seem to be showing up.
