Reduce size of compressed disk images
Did you actually compress the .dmg after noticing the larger size, or was that larger size actually after you had compressed it. Reason I ask is - OS X disk images are quite fascinating objects in that they expand and contract to suit the needs of the contents. This format fo disk image is known as "sparse" in teh documentation, and I believe that its the default when creating disk images with Disk Copy. I may be wrong - but what you might have been seeing - if you had not yet recompressed the .dmg - is possibly a temp size boost. This size difference may have disappeared when you recompressed the .dmg again. Just a theory...

I wasn't using a sparse image - AFAIK the only way to create sparse images is to use the command line tool. The larger size was after I had compressed the image with Disk Copy.

Sparse images aren't that good a solution to this problem anyway. |
