Minimally blanked DVD-RW media can only be recorded in DAO mode (it's
the way it is, period). growisofs does attempt to detect minimally
blanked media and engages DAO in such case, but unfortunately there is
no reliable way to tell apart minimally and fully blanked media and it
might fail to engage DAO with some units. Your options are
- try to growisofs -dvd-compat -dvd-compat, i.e. pass two -dvd-compat
options, to manually engage DVD-RW DAO;
- try to 'dvd+rw-format -force /dev/scd0' to format for Restricted
Overwrite (I personally recommend Restricted Overwrite);
- spend an hour on 'dvd+rw-format -blank=full /dev/scd0';
