Isn't it because the ISO should an CD-ROM format, such as Rockridge,
or Joliet, or ISO 9660, and not a file format that is used on hard
drives? I have created many useless CD-R drink coasters while trying
to burn an ISO to a CD-R disc, because MacOSX often mistakenly asks if
I want to burn the "Contents" of the ISO image to the CD-R, instead of
burning the ISO image on to the CD-R and I forget that doing it that
way does not create a CD-ROM that can be read on other computers.
When I use OSX's Disk Utility and burn the ISO image to the CD-R, I
get a CD-ROM that can be read on any computer.
Hope this helps. (from the new guy, AmigaDave)

Subject: hdiutil help
I'm trying to write a script that turns a zip file into a Windows-
mountable ISO file, and my sticking point is the hdiutil command
creating the disk image.
hdiutil create <image_name> -format UDTO -srcfolder <source-folder-
path>
Works. It creates a .cdr (aka .iso) file with the contents of the
source folder. However the resulting disk image is formatted with a
HFS+ file system, so when you try to mount the .iso file on a wondws
machine (or the disk made by burning it) Windows claims it's
corrupted and unreadable.
hdiutil has a -fs option allowing me to choose MS-DOS as the file
system but trying that results in an error:
mount_msdos: /dev/disk2 on /Volumes/TEST: Operation not permitted
/sbin/mount failed with error 18176
However, it seems to continue to make the disk image.
Anyone know why it' spitting out that error?
(and before you suggest it:
No Toast is not an acceptable solution, nor is using Disk Utility,
this has to be managed on a regular basis by a user who just wants
to stick some stuff in his windows Access database (yes, I'm writing
a Mac utility to create an ISO so Access can use it in his Windows VM)
