Ok, but I know that with cat /dev/cdrom > image.iso I can make an iso
image... and I tried that command with a CD not recorded in my Writter
and it works.

I think it could be that I don't do the things well when I record a CD.
I used the following command:

        mkisofs -q -r cdvarios | cdrecord dev=0,1,0 speed=16 \
		driveropts=burnproof fs=15M -

I have read that I must give tsize option to the cdrecord, could that be
a mistake? must I do that or is not needed?

Now, could you tell me where can I find information about this kind of
problem? I was searching in google and nothing... :(

Thank you.

Sorry for my english.
