Are you sure that was not 200meg free and now you are at 4meg. 200Gig to 4meg is a HUGE difference. Even if you were on line at a 16meg connection it would take you many many days to download 200Gig.
Even if you were Ripping DVDs; you would have to Rip 25 movies to fill 200gig of space up. Ripping 25 movies if everything went perfect would take over 12 hours.
