quote from Thomas Schmitt,
looks like a problem with cdrecord and multi-session on DVD-R.
Possible reasons are:
1) The first cdrecord run was not done with option -multi.
I.e. the DVD-R is closed when the second run is attempted.
2) Option -sao of the second run spoiled the attempt to add a session.
-sao could trigger write type Disk-At-Once which is not appropriate
for media which already contain data.
3) cdrecord could be unwilling to do multi-session on DVD-R.
I deem this unlikely, because i have seen reports that it works
with DVD-R.
Investigations and tries:
1) One should inspect the DVD-R after the first run by runs like
cdrecord dev=/dev/sr0 -minfo
dvd+rw-mediainfo /dev/sr0
xorriso -outdev /dev/sr0 -toc
cdrskin dev=/dev/sr0 -toc
xorriso would report for a DVD-R which capable of taking more data:
Media status : is written , is appendable
and for a DVD-R which cannot take more data
Media status : is written , is closed
2) If the medium is reported to be "appendable", then leave out options
-sao and -tsize. I.e.
cdrecord -v gracetime=2 dev=/dev/sr0 speed=16 driveropts=burnfree -multi
-waiti -data ./some_image_file
3) Try whether cdrecord does multi-session when run by command line
cdrecord -v -multi dev=/dev/sr0 ./first_image_file
cdrecord -v -multi dev=/dev/sr0 ./second_image_file
Above inspection commands should afterwards report 2 sessions.
