Hi Folks, I have a backup of my system in an "exustar" .star archive file. Its 7.5 GB in size. I want to write this file to a Double Layer DVD+R disk which claims to be 8.5GB in capacity. I have tried growisofs, and K3B, and I can't seem to find the magic incantation which will allow me to do this: > growisofs -dvd-compat -dry-run -speed=2 -Z /dev/hdd root.star > Executing 'mkisofs root.star | builtin_dd of=/dev/hdd obs=32k seek=0' > INFO: ISO-8859-1 character encoding detected by locale settings. > Assuming ISO-8859-1 encoded filenames on source filesystem, > use -input-charset to override. > mkisofs: Value too large for defined data type. File root.star is too large - ignoring > Total translation table size: 0 > Total rockridge attributes bytes: 0 > Total directory bytes: 0 > Path table size(bytes): 10 With K3B, when I try and move the root.star file into the DVD Project window (after making it 8.0GB in size), I get a popup telling me that K3B can't move files bigger than 4GB! Is this a limitation of the DL format? single files can't span the layers? I've read the "Blu-ray Disc/DVD+RW/+R/-R[W] for Linux" document by <appro@xxxxxxxxxxxxxx>, and the only thing I can find on the subject says: > # And when it comes to DVD+R Double Layer and DVD-R Dual Layer recordings, > growisofs applies yet another limitation, purely artificial. Taking > into consideration Double Layer media prices growisofs is programmed to > refuse to perform unappendable recordings which are less than 1/2 of > blank capacity and to advice to use single layer media instead. Well, what I saw was growisofs very nicely eliminated the 7.5GB file and burned me an empty fs. B^( Using the -overburn option doesn't seem to help with growisofs. I also tried with nautilus-cd-burner. I was able to move the 7.5GB file into my session, but the attempt to burn it errored out with: > An unknown error occured while writing to the DVD" I even tried writing directly to an image.iso file with nautilus-cd-burner, but the resulting image.iso contains an empty filesystem (and is only 370688 bytes in size!) and doesn't produce any visible error messages. What's my solution? What am I missing? Do I need to break my single 7.5GB file into 2 smaller files in order to burn them onto the DL DVD+R? Why isn't there a HOWTO that talks about the details of burning a DL-DVD+R and the practical limitations? (Most of what I've found pertains primarily to Video DVDs, and while they are both technically Data-DVDs, there are practical differences, as I want to burn a single large file into my filesystem....)
