How to Convert a Clone CD Image to ISO

April 26th, 2008

Just ran into a time consuming hiccup trying to work with a Clone CD Image. I hope the rather detailed explanation below will help someone else deal with a Clone CD Image faster on his Mac.

I'd downloaded a 600 MB disk image to use with Parallels. The disk image came wrapped in a .rar format.

Unpacking the .rar file was very difficult.

• StuffitExpander crashed
• Forklift couldn't handle it
• Archive Utility just wanted to compress it further.

Finally I was able to unpack it with IAarchiver, slowly but certainly.

After unpacking, I was offered a directory with three files in it:

• image.img
• image.ccd
• image.sub

Clone CD img ccd sub files

I had no idea Windows used the archaic Mac .img format. It turns out that Windows doesn't. What I'd inadvertently downloaded is what is known as a Clone CD image. I was unable to mount it on my Macbook. No known solution or software for Mac OS X can handle Clone CD images. BIN and CUE files are no problem, but CCD files - there's nothing out there.
