I have a FreeBSD system whose CDRW drive is working well
and I can use mkisofs and burncd to make conventional
single-session CD's. I just attempted to write a CDRW using the
UDF or Universal Disk Format file system which is built in to
FreeBSD and is supported in mkisofs at least to some extent
according to the documentation.
I wrote two test files to the CD with the following
command
mkisofs -l -R -udf -q /home/martin/cdroot/ | burncd -q -f /dev/acd0c data -
Do you just keep running that command or something
similar when there are new files to write to the disk and then
run the fixate command in burncd when the disk is as full as you
want it to be?
I basically thought that is what the documentation said,
but when I mounted the CDR on another system, I only saw the
first file I wrote and nothing more.
In my test, I wrote that first file in the directory
called cdroot, did the UDF burn, removed that file and replaced
it with another one of different name, did another UDF burn and
then fixated it.
If it was a CDR, it probably would be a coaster now.:-)
