Anyway, I always wqas lucky using growisofs (from port dvd+rw-tools). This is the command: # growisofs -dvd-compat -Z /dev/dvd=3Dfoo.iso You can replace /dev/dvd with the ATAPICAM device refering to your DVD recorder, usually something like /dev/cd0. The command # camcontrol devlist shows you the device name (l=F6ok for the SCSI ID 1,0,0 as from your cdrecord example). > what are the magic commands to use from the cmdline to=20 > erase my dvd? is there a utility to erase? In "man growisofs" I found this: Note that DVD+RW re-formatting procedure does not substitute for blanking. If you want to nullify the media, e.g. for privacy reasons, do it explicitly with 'growisofs -Z /dev/dvd=3D/dev/zero'. This should work, or try the respective cdrecord blank=3D command (all or fast). --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
