There may also be a lock switch on the card itself or an SD card adaptor, if 
connected to the PC using an adaptor, although I expect Dale would have 
noticed that feature and unlocked it.  Sometimes the lock switch is faulty and 
will only make contact half way through, switching back to read only at the 
fully unlocked position - they don't make things as they used to anymore.  :(

Let's not forget corroded electrical contacts - I've had that happen with a 
USB stick, which accidentally fell in a cup of coffee.  LOL!  The coffee 
corroded the copper, but the problem only became apparent intermittently a 
week later.  Cleaning the contacts with fine wire wool and blowing away all 
swarf followed by a wipe with methylated spirit allowed me to access my files 
again.

To eliminate PC/adaptor problems, reinsert the card in the camera device it 
came with and delete/format it there.  If it still doesn't work, RMA it under 
warranty, or buy a new card, of a different make.  Then tell us all what make/
model it was, so we can all avoid it!  LOL!

PS. exFAT has made it into the latest Linux kernels.
