There are platform where it works. :-) What do you mean by "destroy" - make it unreadable before or after something has been burned onto the CD-R? You can use /dev/random to fill the writing process for tools like cdrdao or cdrecord, e. g. dd if=/dev/random bs=1024 count=100 | cdrecord -tao -data - Maybe you need to set specific options (dev=, speed=) for your recorder. However, after a successful recording, it's easier to destroy the CD-R physically. If the session (and media) is already closed, the same idea applies. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
