How Do I Remove Free Space From A Dog So It'll Fit On A Cd?

[Jonukas]

#$^@ Lion autocorrect. I meant dmg, not dog!

 

I'm trying to make a hybrid Mac/PC CD using the Disc Image Merge feature, but I'm having a hard time making both images fit onto a CD.

 

The ISO image is 109.4 MB on disk and the mounted volume shows both the used space and capacity as 108.3 MB with 0 bytes available. That's fine. My problem is with the Mac image. It is 177.4 MB on disk but the mounted volume shows the capacity as 681.6 MB with 519.2 MB used and 162.4 MB available. Toast shows the merged image size as 754.4 MB (ISO: 104.4 + DMG: 650 MB).

 

How can I convert or otherwise remove the free space from the .dmg file so that everything fits on a CD? I've tried using 'hdiutil resize -sectors min -nofinalgap' but that doesn't seem to work.

 

Any advice?

Disk Utility allows you to make a DMG any size you want. When you go to create a New Image, select Custom... from the Size drop-down.
