Default Burning BDXL M-Dic with OpenBSD

I'm about to try backing up some old files to BDXL M-Disc 100MB. I don't want to make $20 drink coasters, so I thought I say what I plan to do and see what OpenBSDers think:

From searching here I found the following advice which looks good.

Optical ISO creation: I use mkisofs from sysutils/cfrtools for CD9660
filesystems, and sysutils/udfclient for UDF filesystems.

Disc Burning: I follow the guidance in the FAQ, and use cdio(1) for CD
media, and growisofs from sysutils/dvd+rw-tools for all other optical media.

http://daemonforums.org/showthread.p...ight=growisofs
I also looked on the net and found a user saying growisofs didn't write 100GB disks correctly and he was told they would not fix it and I started to worry.

growisofs stops short of media maximum

Then I found this advice which seems to fit the above issue:

Reliable Burns with Links

Burning Blu-rays on Linux can be a pain, and often results in useless
"coasters" from failed burns.

The most reliable method is to create a UDF using k3b or Brasero (but only
create image, don't burn). Then you use CDRTools to burn, rather than
growisofs (which spits out a strange "error").

So I thought make the iso using udfclient as jggimi suggests, but then use cdrtools to write it to the BDXL. What do you think? Should I do that or trust growisofs?

My understanding is that k3b/Brasero are front ends to cdrtools. My system will not utilize sysutils/dvd+rw-tools to back up files in one step. What works well for me is to generate an *.iso using mkisofs and then use the following from growisofs(1)

Code:
growisofs -dvd-compat -Z /dev/rcd0c=image.iso
You may need to adjust your character device per the same man page.

I have not used this w/ blueray but it worked with a Dual layer dvd.

It appears that the dvd+rw-tools developer did not have BD-RE hardware to recreate the reported problem with growisofs, and recommended xorriso as a possible solution. dvd+rw-tools is not actively developed, its last update was in 2008.

OpenBSD has a package of xorriso.

I know nothing about the software tool, but a quick browse of its features indicates it is for CD9660 file systems, it does not apparently support UDF.

sysutils/dvd+rw-tools upstream does have some info on BD-RE
http://fy.chalmers.se/~appro/linux/DVD+RW/Blu-ray/
It also mentions an -udf option

Recently I had time to try to get this to work and ran into an issue that I thought OpenBSD newies might want to know about.

I used the recommended command from the FAQ to make an image:

mkhybrid -r -J -o file_name.iso /directory_name

But when I mounted the image and tried to copy the files back, there was a copy error on some files and not others.

It turns out the files were too big. I thought 4 GB would be okay, but it has started working when I made them 1 GB.
