However, when I attempt to add data to it, it bombs out. I created a script and then used it to try and add two files to the disk using your instructions.

As you can see, nothing was written. I am using brand new CD/R disks that work on other platforms so I don't think that is the problem. since I can create the original disc, I can obviously write to one. do you have any ideas what the problem might be?
