OK, using your instructions, I am able to create the disk just fine.
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.

This is the output:

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?

Thanks!
