How do I write DVD?
You need to use growisofs command, which combined mkisofs frontend/DVD recording program. From growisofs man page, "growisofs was originally designed as a frontend to mkisofs to facilitate appending of data to ISO9660 volumes residing on random-access media such as DVD+RW, DVD-RAM, plain files, hard disk partitions. In the course of development general purpose DVD recording support was implemented, and as of now growisofs supports not only random-access media, but even mastering of multiession DVD media such as DVD+R and DVD-R/-RW. In addition growisofs supports first-/single-session recording of arbitrary pre-mastered image (formatted as UDF, ISO9660 or any other file system, if formatted at all) to all supported DVD media types."
First create the ISO image
# mkisofs -r -o /tmp/var-www-disk1.iso /var/www
Now use the growisofs command to write the ISO onto the DVD:
# growisofs -Z /dev/dvd=/tmp/var-www-disk1.iso
To append more data for same DVD:
# growisofs -M /dev/dvd /tmp/file.1
To format (erase) a DVD:
# dvd+rw-format -force /dev/dvd
# dvd+rw-format -force=full /dev/dvd
The dvd+rw-format command formats dvd disk in the specified dvd drive.
To display information about dvd drive and disk using dvd+rw-mediainfo command:
# dvd+rw-mediainfo /dev/dvd
