write on cd-RW in udf file system

[nouvo09]

Hi

I tried to write on a udf fs formated cd-rw where there was already some backups. While there is no problem to read the content, I was unable to add new files on it.

I installed udftool and tried but I just only ruined this backup header.

So does anyone know how to use the cd-rw as as floppies ?

Thanks
