+
+ {\bf Mounted Media} line should give you the information.
+
+ To set the device to {\bf Restricted Overwrite} mode, run:
+\begin{verbatim}
+ dvd+rw-format /dev/xxx
+\end{verbatim}
+ If you want to set it back to the default {\bf Incremental Sequential} mode, run:
+\begin{verbatim}
+ dvd+rw-format -blank /dev/xxx
+\end{verbatim}
+
+\item Bacula only accepts to write to blank DVDs. To quickly blank a DVD+/-RW, run
+ this command:
+\begin{verbatim}
+ dd if=/dev/zero bs=1024 count=512 | growisofs -Z /dev/xxx=/dev/fd/0
+\end{verbatim}
+ Then, try to mount the device, if it cannot be mounted, it will be considered
+ as blank by Bacula, if it can be mounted, try a full blank (see below).
+
+\item If you wish to blank completely a DVD+/-RW, use the following:
+\begin{verbatim}
+ growisofs -Z /dev/xxx=/dev/zero
+\end{verbatim}
+ where you replace xxx with your DVD device name. However, note that this
+ blanks the whole DVD, which takes quite a long time (16 minutes on mine).
+\item DVD+RW and DVD-RW support only about 1000 overwrites (i.e. don't use the
+same medium for years if you don't want to have problems...).
+
+To write to the DVD the first time use:
+\begin{verbatim}
+ growisofs -Z /dev/xxx filename
+\end{verbatim}
+
+To add additional files (more parts use):
+
+\begin{verbatim}
+ growisofs -M /dev/xxx filename
+\end{verbatim}
+
+The option {\bf -use-the-force-luke=4gms} was added in growisofs 5.20 to
+override growisofs' behavior of always checking for the 4GB limit.
+Normally, this option is recommended for all Linux 2.6.8 kernels or
+greater, since these newer kernels can handle writing more than 4GB.
+See below for more details on this subject.
