cdrecord multisession not working

I'm trying to burn multisession CDs. It doesn't appear that gnomebaker supports it, so I'm trying to do it using mkisofs and cdrecord.

I started by using mkisofs to create an image: mkisofs -v -r -J -V MyLabel -o myimage.iso mydata

I then burned it using: sudo cdrecord dev=ATAPI:0,0,0 -v speed=4 -data -eject -multi -tao myimage.iso

This worked fine and I could view the data under Linux and Windows.

For the next session I ran: sudo mkisofs -v -r -J -C 'cdrecord dev=ATAPI:0,0,0 -msinfo' -M ATAPI:0,0,0 -o mynewimage mynewdata

I used sudo because cdrecord needed it. I forgot the .iso extension (but I don't think that matters).

I tested the new image using: sudo mount -t iso9660 -o ro,loop mynewisomnt-iso

Everythiing looked good. I new all files and listed and I was able to access the new file I just added.

I ran: sudo cdrecord dev=ATAPI:0,0,0 -v speed=4 -data -eject -tao -multi mynewimage

It looks like it ran fine, but when I mount the disk I only see the first session's files. It looks like cdrecord did not write the new TOC. I ran cdrecord 2 more times playing around with unmounting to see if I had a lock problem, but the same thing happened. cdrecord looks like it worked (it writes about 5MB which is the size of the new file I added), but I can't get access to it.

I tried loading the CD on a Windows machine, only could see the original files.

I ran: sudo cdrecord dev=ATAPI:0,0,0 -toc

It shows 4 tracks (one for each of the sessions I wrote). I tried mounting the CD with -o session=4. But it still only shows the original files. I tired mounting using -o sector=love but mount would not work.

The only thing I see is I get this message when running cdrecord:

I'm running Ubuntu Hoary Hedgehog.

Is this a known issue with the version of Linux I'm running? Does anyone have any ideas on what I'm doing wrong?

Thanks,

Steve
