just posted this in an apple.com forum. Let's see who responds first.... I keep reading that there is no way to add info to a CDRW without erasing the whole disk and starting over. Or doing a multi session burn using disk copy which sounds like a pain. This is a major disappointment considering my old PC running win98 can use CDRW disks just like a floppy disk. I just drag and drop a file and eject and it's on there. I can add or delete files at lesure while never having to completely erase the disk. What's the deal? Why can't I do this on my Mac?
