Just a question for verification: Do you use such SD cards in
a camera, and will the camera accept FAT and UFS? I have never
heared of such a camera, but...

Of course let's never forget that there are other use cases
for SD cards than just putting them into cameras and phones.
For example, I use USB sticks with _no_ filesystem on them
to transfer data (using tar). I do not know if any non-UNIXy
or non-Linuxy system will be able to read or write them, but
luckily, I don't have to care about that. :-)

Yes, you can use gphoto2 (uses libgphoto) as a convenient
CLI tool, as well as gtkam for GUI access. For example, my
(old) camera supports both PTP and mass storage mode (can
be selected in the camera's menu), but personally, I found
it just easier to remove the SD card, put it into the reader
built into the computer, use it from there, and put it back,
instead of dealing with the USB mini-B socket and its lousy
protection cap, oh, and where did I put the cable... ;-)
