Rescue CD imaging whole drive, not just data

I am trying to get an image on my new laptop before I start to do anything with it. I have a 40 gig hdd with only 5 or so gigs of data. My images are coming out at 37 gigs, not the 5 that it should be. I have imaged machines before without any problems, but this particular pc won't coopperate. Any ideas

 

what filesystem is used? which os?

do you use some ez-driver, another "hdd-tuning" ore compressing tool which interact with partition handling?
