I just picked up a 4 gig Sandisk CF card from Dell. I noticed something that I did not see in the instructions and it is hard to find. On the side there is a little tiny dip switch that can be set to 4 gig fat32 or 2 gig fat 16. There are two 2 gig settings. This I believe is so that you can use the card in a camera like the D1x which does not support fat 32. In a D1x use the card set at fat 16 2 gig and then when you fill this switch the card to the second fat 16 2 gig positon to get full 4 gigs. I guess this is a partioned disk. I just wanted to share because it did not appear to be obvious and I did not see it in the manual.
