Problem creating ISO

I want to create an ISO image of a folder on my disk (10.7.5)

Googling led me to instructions that said to open Disk Utility and select File, New, Disk Image from Folder That isn't working... first, I get a prompt for administrative credentials, which makes no sense, as I can read and write to the folder in question no problem. But if I supply them and hit Save, I get an error Unable to create "<name of folder>" (Permission denied) even though, again, I have write permission to my desktop or anywhere else I've tried to save it.

give burn a try

Burn - Home

Just what folder is this you are trying an ISO of?

Would it make a difference? It's a collection of software and scripts and documentation.

Yes, I was being sure it was not some system folder that was part of the OS as you would probably get that error. Where are you trying to write the ISO to? Same folder? Another folder? Desktop?

All of the above.

What is the exact error Disk Utility is giving? I am wondering if it's some files in the source that are causing the error. I have never had a destination error making IOS's with DU before.

Unable to create "<name of folder>" (Permission denied)

I've tried different names, thinking it didn't like to be called the same thing as the source folder, or if it was too long, or ???

I have gone into the Get Info for the folder at pushed out permission changes through the whole thing just to make sure that I can read and write. Maybe I'll grep through the whole tree looking for anomalous permissions...

Tried again after

find /path/to/directory -exec chmod -N {} \;
find /path/to/directory -type f -exec chmod 644 {} \;
find /path/to/directory -type d -exec chmod 755 {} \;

Now, it takes the time to look like it's building the image, but when it gets done, the image disappears and I get an error 'Unable to create "<name of folder"> (Operation not supported)' Again, this is as a user with admin privileges, and writing to my own desktop, so... how do I find out what it's unhappy about???

I had a chance to come back to this and look a little more. In /var/log/system.log, I'm seeing:

The file in question, though, is in /Volumes/Data/Setup\ Disc/...

Why is the copy process dropping the "Data/"?

Still hoping for some ideas...
