imaging question

[Steven M. Sawczyn]

I recently reinstalled Windows XP on my bootcamp partition and so as  
to make the process easier for next time, thought I'd use Disk Utility  
to make an image.  Although the partition only contains 3.7 GB, the  
compressed DMG is 8.92 GB.  Anyone have any ideas why the image is  
larger than the data on the partition?  More importantly, does anyone  
know of a way to compress, or somehow make a smaller image?  I'd  
really like to use Disk Utility if possible as I could then easily  
restore the image to the Bootcamp partition, at least I'm thinking  
that should go rather smoothly.

Thanks for any help,
Steve
