Click on the remaster.iso

copy all files into the directory you just created.

unmount bluray drive,

Here is the on the fly burn command string, started in a terminal with current directory you moved the remastered files into.

Code:

growisofs -use-the-force-luke=notray  -Z /dev/sr0  -f -iso-level 3 -D -R  -V \"BluFatDog620\" -p root -publisher \"Ted_Dog\"  -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table ./

OK class let me know if this works for you..

The save session code is always going to fail until we make the changes coming later.

Please reply once you successfully booted with the remake.

The changes made for Bluray, are 100% compatible with DVD you just will not see files larger than 4G or hit the other boundary that kept Bluray from sessions beyond DVD size.

The disc may not be readable on older XP windows, but please check and let me know what happens with your Window if you dual boot and tried this. I have no way to check...

Ted Dog, does it still work if you change iso-level to 4 instead of 3?

No, when you use the iso-level setting of "4", mkisofs actually use iso9660:1999 specification. This is the "supposedly" proper way to use -D (ref: http://linux.die.net/man/8/mkisofs). I can confirm that if you use this setting, the disc is readable fine under Windows XP. The question is whether it can still burn > 4GB files and whether there are any specific bluray stuff that fails.

I've tested removing the -J (change it to -D) and changing iso-level to 4 for all the 3 possible places:
- save multisession
- remaster
- iso builder
and I have tested saving session under these conditions, it seems to work fine.

Growisofs has a calculation bug that effects multisession being written somewhere near the 10G mark.
This is not a limit on these settings, to prove that I added files to a directory inside the directory holding the files needed to boot FatDog64 those added files totaled 22G with one over 10G in size.

Of course I had to use a USB harddrive, not build from RAM for that test.

This is my method of backing up large stuff, Organize files into directories to 22G limit. by moving stuff rather than copying.

I see. So does using iso-level setting of "4" instead of "3" still work? Because like you say above, it seems that the only thing that needs to be changed is:
a) drop -J
b) add -D
I've done both a) and b), but in addition to that I'm changing iso-level from "3" to "4", so I wonder whether it still work? The manpage doesn't exactly say that iso9660:1999 relaxes the size restriction of earlier iso9660 spec (which "iso-level 3" does).

As for why it doesn't work for others puppies (including earlier Fatdogs), is probably because in 620 we now use the latest cdrtools (earlier Fatdogs uses cdrkit - a fork of cdrtools which seems to be no longer updated after 2010). I think many puppies (with the exception of Slacko) perhaps still use cdrkit.

cheers!

@jamesbond,
Thanks for clearing that up for me, level 4 is a modified version of level2 with changes to support nested directories beyond the level 2 native support.

As a level 2, I doubt that the 4G boundaries are leaped. However easy enough to test.

Weather has cleared up nicely, but my grass has shot-up overnight, I see mowing in the next few days. Mad

Thanks for the heads up on why fatdog64 works and other puppies don't

@jamesbond

Would you rewrite this line and the other to send warnings and error msgs to /tmp for debugging ms issues in the future.

Code:
   ! $GROWISOFS -root $archivepath "$SAVEFILE_MOUNT"/archive/* > /dev/null && save_ok=no   



code snippit from /usr/sbin/fatdog-save-multisession.sh

Ted, is there any chance that Fatdog64-611-SeaMonkey will work instead of Fatdog64-620? I already have the iso and I prefer SeaMonkey to Firefox.

see

Does not look like it, plus v620 is a rock solid release worthy of the bandwidth used Wink I have to say its the BEST puppy in any form/spin in the last 18 months. Shocked

And it has SeaMonkey Very Happy

I can also confirm that "-D -iso-level 4" is a replacement for "-J" in XP and Win7. This is both when writing directly to a data DVD and making an ISO to burn data onto a CD.

This argument throws a warning message about filenames longer than 31 characters, but it doesn't appear to be a problem.

I didn't look at any bootable disc / multi-session scenarios.
