Re: cdrecord: no blanking of CD-RW possible



Hi Christoph,

I don't have all the answers, but hopefully this points you in the
right direction.

Judging by the output you posted it would seem that there are no
errors, so the CD should have been blanked. The toc command failed. To
me that would indicate that there is no toc and therefor the disc is
empty.

With such a line it seems you are trying to blank the disc and burn an
iso to it in one go. I suggest you try this with two separate
commands, so that would be something like:

cdrecord -v -blank=fast dev=0,6,0 speed=4

cdrecord -v dev=0,6,0 speed=4 ./sarge-i386-1.iso

You seem to be making a multi-session cd then. There is no need for
that, as the sarge iso will take up almost all space on your cd
anyway. Just make it a 'normal' cd.

Maybe you need to explicitly specify the write mode you need for your
drive. I'm no expert there though, so I would redirect you to the man
page for cdrecord. Supported modes for your drive as reported by your
cdrecord output are TAO PACKET SAO SAO/R96P SAO/R96R RAW/R96R.

Perhaps you could tweak the defaults in /etc/default/cdrecord.

HTH,
