Hybrid Data Cd Using Udf Instead Of Iso9660

I can't think of a reason why the client would want UDF over ISO 9660, though. Are there filenames over 64 characters (one possibility)? There won't be files > 2 GB on a CD, so that won't be a reason.

Perhaps you are aware of the following, but... Could it be that the reason for wanting change is that they see strict ISO 9660 filenames (MYDOCUME.EXT (MS-DOS style)) for ISO reading, instead of longer filenames with mixed case and extended characters? If so, that could be solved by setting [select ISO] > Settings tab > Naming: "Joliet (MS-DOS + Windows)".

 

Thanks. I don't know specifically why they asked me to consider this; I suspect it was more about matching some work done on another part of the system. Thanks for taking the time with such a thorough reply.

Toast differentiates between "Mac & PC" (all files visible to both platforms) and "Custom Hybrid" (reveals certain files when the data disc is used on a Mac, and certain other files when it is used on a PC). We use Custom Hybrid, and the question I have been asked is "can you make the CD a UDF rather than a ISO9660 and still maintain the HFS+ partition?" I think the answer is no, but I am not certain of that conclusion; that was the reason for my post.

 

Perhaps I was not clear that this is a Data CD, not a DVD.

 

Thanks for your attention.

You are correct that the answer is no.

Ah, okay, now I get it.

The user interface of Toast doesn't provide a way of selecting such a custom hybrid. But in theory it should be possible to construct such.
