#17. "RE: lossless vs. uncompressed - what are you doing?" In response to In response to 14 Mon 16-Sep-13 02:00 AM by jrp

I am not aware of Nikon software to convert uncompressed NEFs into lossless compressed NEFs, except for Capture NX2, where -as Gary mentioned- a dialog pop-up window comes up for you to select the format.
It is a one-at-a-time thing. Maybe that can be batched.
As for the images capacity from the card, that is always a very safe (conservative) estimation, not an accurate calculation reading.
