Append data to DVD R

I have successfully used growisofs to append content (data / files and folders) to a DVD+R.

invocationEdit

general formatEdit

the format for composing such a command (line (invocation)) is:

growisofs -speed 2 -M /dev/dvd (mkisofs/genisoimage command line goes here).

The "-speed" switch is optional.

particular exampleEdit

Here is my particular example:

# growisofs -speed 3 -M /dev/dvd -A 'myName' -sysid 'WifiSlax 4.7Final' -udf -joliet-long -long-rr-time -r errctl="WARN|ALL *" -iso-level 2 -N -publisher 'udf joliet-long -long-rr-time -r -iso-level 2 -N ucs-level 1' -p 'implicit -pad, right? no charset specified use-fileversion errctl="WARN|ALL *" ' -use-fileversion -ucs-level 1 -V 'Econee cPanel backups2013nov' -v -v -v -gui -log-file=growisofs-speed3-M_-v-v-v-gui.log.txt -graft-points sears500WD-Temp-econee_whm_cpanels=/mnt/sears/Temp/econee_whm_cpanels/

resultEdit

When I query the blkid (information for the block device) of the optical disc, it still shows information about the bootable first track/session which is the (exact) same as before growisofs -M was run, when there was only one session on the disc.

blkidEdit

# blkid /dev/sr0
/dev/sr0: LABEL="slackelLive_kde-4.10.4-64" TYPE="iso9660"

initial session was burned usingEdit

Note: the initial session (And track) on the disc was burned with:

growisofs -speed 4 -Z /dev/dvd=slackellive-kde-4.10.4-64.iso


Next, I decided to query the disc state (status) (stats) usng dvd+rw-mediainfo and then cdrdao disk-info and msinfo commands/modes/operations:
