Space gobbled

[pupino]

I use an iMac G5 1.8 with 768mb o ram, an 80 gig internal hard drive. I just bought and used super duper to make a copy of my hard drive which had aboot 39 gigs of room before I made said copy. After said copy to an external firewire drive, erased and partitioned prior to coping. I now am down to a tad over 17 giggies left on the internal hard any ideas where or what happened to aboot 20 giggies of space. I am so
