Re: Dead CD-R burn...
It is highly recommended to first preopare the image with mkisofs.
check it with loopback device and only then burn it.
Most CD-R's depend on the speed their internal buffer is being fed.
If there is a delay the CD will be unusable.
Try to run mkisofs to a disk image,
Then test it with
mount -t iso9660 -o ro,loop=/dev/loop0 imganame /mntpoint
Only then run cdrecord from the Image.
I have burned this way Hundreds of CD's under Linux without a single
problem.
