With a CF/SD card formatted in a camera there will be a camera specific 
DCIM folder, contained in that folder will be a nested folder labelled 
with the camera manufacturer's name and folder number giving you 
something such as this: 100_FUJI, 101_FUJI, 100_D300S, 101_D300S, etc.

Once Photos and Image Capture have been configured not to open files 
from the device/card/camera, you will be blisfully undisturbed by 
Photos.

It is the software treating the SD/CF card as a device. The mounted 
card will still be accessible via the Finder. Lightroom it will treat a 
mounted card as an Import source. Bridge will treat a mounted card as a 
drive.
