Hi: Does anybody know how to specify "where to put the layer break" while writing a large ISO image (6+ GiB) on a 8.5 GB DVD-R DL disk ? Do we need to calculate this or is there an option that we can use so as to enable to tool to compute it by itself ?
Long Story Have to write a 6+ GiB bootable ISO image on a DVD Normal DVD is 4.5 GB so it cannot be used Dual Layer DVD or DVD-R DL hold 8.5GB as they have two recordable dye layers. I bought a Sony 8.5 GB DVD-R DL and used growisofs to write the ISO image, by issuing the following command the device that maps to DVD writer is # ls -l /dev/sr0 brw-rw---- 1 root optical 11, 0 Dec 4 12:50 /dev/sr0 Hence the command issued is, # growisofs -dvd-compat -Z /dev/sr0=mybootable.iso The DVD writing process started as usual and then stopped with an ERROR exactly when one layer (approx 4.5 GiB) was written :-[ WRITE@LBA=1fdb40h failed with SK=3h/ASC=0Ch/ACQ=00h]: Input/output error :-( write failed: Input/output error The versions of the tools are as follows: # # growisofs -version * growisofs by <[email protected]>, version 7.1, front-ending to mkisofs: mkisofs 3.02a07 (x86_64-unknown-linux-gnu) # # cdrecord -minfo -v Cdrecord-ProDVD-ProBD-Clone 3.02a07 (x86_64-unknown-linux-gnu) Copyright (C) 1995-2016 Joerg Schilling TOC Type: 1 = CD-ROM Linux sg driver version: 3.5.36 Using libscg version 'schily-0.9'.
