Default Cannot burn CD's succesfully.

Cannot burn CD's succesfully. ( post #1)

Yo!

Please help, I have fighting with this for long time. :-)

I would like to create such a cd which supports multisession, which probably means that I can continue the CD later until its filled and it must be closed.

But this seems totally impossible task for me. When I try to burn ISO file for my cd rom it can burn only one track. Right after that the cd seems to be totally closed no matter how much space is left on the CD-ROM. Very strange, but this surely is CODE 18, isnt'it?

So what is wrong with these flags which I use:

mkisofs -v -J -r -f -l -multi -iso-level 3 -hfs -hide-rr-moved -o varmuuskopio2.iso /home/tommi/isottelut

And it creates a cute ISO file which I can burn, good.


Then I use cdrecord:

cdrecord -v -multi -eject speed=6 dev=0,0,0 varmuuskopio2.iso

And it burn the file and everything is O.K. But when I try to continue the record, it says like this:

bailing out..

It looks like the CD-ROM is totally closed and its all but multisession. BTW...does iso support multisession? Which file I should use if that is the case...?

Hi Tommi,

it's a good idea to add a cd-burners group if you are planning to write cds with your normal user account.

try burning your CDs as root user or do a
chown root:root /usr/local/bin/cdrecord
chmod u+s /usr/local/bin/cdrecord
to run cdrecord in suid-root-mode.

if this doesn't help check how you created
the iso-images for the 2nd, ..., n-th session:
you have to use cdrecord's switch "-msinfo" to retrieve information about the sessions already on CD. See manpages on cdrecord and mkisofs an the cd-writing-howto.
