Burning multisession problem

Hi,

 I've bought the cd recorder LG GCE-8520B and I'm trying to use it in multisession.

I can't understand the behaviuor of mkisofs...I mean: at first creation of ISO9660 image everything works fine, but at the moment I use the command:

mkisofs -r -J -C `cdrecord dev=0,0,0 -msinfo` -M /dev/cdrecorder -o  immagine2.iso /opt/TEST

I have always to eject and re-insert the cd to have the new image.

When this happens mkisofs exits with error:

<mkhybrid: Success. Read error on old image>

Is there a way to resolve a such problem?

Thank you,

 Fab :)
