Some software may automatically finalize if there is not much space left. I have used cdrecord and growisofs. >The ISO image is an "image" of what's going to be burnt onto the disc, >virtually all the pits and bumps. You are quite wrong about this. An ISO image only contains the data for an ISO9660 volume, which can be written to a CD or DVD, or loopback mounted from a file. The ISO image has /none/ of the pits and bumps of the various colored books. It is just the data for an ISO9660 filesystem. >That isn't just the files, but the >file system, as well - everything that goes onto the finished disc. >It'll include all the bits that burning software also writes with files >indicating that the disc is closed.

If it did, it would work on CDs or on DVDs, one format only. It is just the data for an ISO9660 filesystem. >Having to finalise a disc burnt from an ISO image is an abnormal >requirement. You are wrong. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
