I'm still experimenting with my D70s! I shot some photos, transferred them from the camera to a folder on my PC and was able to read the EXIF data via Properties>Details. I just tried again and the data are missing!
Very weird. After I posted this, I tried again and the data had returned. But I just tried again now and no data! I'm still running 8.1 and I these are not yet processed. Some are jpeg and some are RAW.
