The only reason not to compress when using a lossless method is normally is to save the processing overhead of compressing and decompession.

Rob,
Your question really got me thinking and as a result I have spent a good slice of today trying to find an answer.
The only info on the subject I can get is from Thom Hogan reviews. From these the D100 RAW is not compressed but the D70, and D50 are. As you are the tech. type I will link both of his reviews. The info is half way down the page. In his review of the D2X there is no mention of Compressed RAW but it would seem logical that it is the same as the D50 & D70.
We now need a couple of tests from Stephen when he has some time.
