Re: Adding data to existing CD/DVD (FIXED)

[Jerry]

I found the problem. I had to manually set the '$dv" variable.
Actually, I have "CDR_DEVICE=3,0,0" set in the environment  so all I had
to do was use for mkisofs.

It still outputs some error notations; however, I assume that they are
harmless.

Thanks for your assistance.

OK, using your instructions, I am able to create the disk just fine.
However, when I attempt to add data to it, it bombs out.

I created a script and then used it to try and add two files to the
disk using your instructions.

This is the output:

As you can see, nothing was written. I am using brand new CD/R disks
that work on other platforms so I don't think that is the problem.
since I can create the original disc, I can obviously write to one. do
you have any ideas what the problem might be?

Thanks!

You need to *not* fixate the disk, and on subsequent sessions you need
to tell mkisofs where to start the new image.  The burning command also
needs to know that it's a multi-session disk.  See the "-C" option for
mkisofs, and the "-multi" option for cdrecord.

My crib sheet for burning disks provides an example:

# first session
TZ=UTC-5 mkisofs -R $filenames |cdrecord -v driveropts=burnfree -multi
-data -tao -

#other sessions
OFST=`cdrecord -msinfo`
echo $OFST
TZ=UTC-5 mkisofs -M $dv -C $OFST -R $filenames |cdrecord -v
driveropts=burnfree -tao -multi -data -eject -

Certainly the sysutils/k3b port makes it much simpler.  But the command
line is quite easy too, now that I have a working script written down.
