Don't count on it. At work there are several plc's, and robots that use sd cards for program storage. If you place one in a pc, write protected or not, The pc reports that the disk is "unformatted". The card becomes unusable by the plc, and has to be reformated by the plc.
There are utilities that can do binary transfers to and from the sd cards, but I suspect something is going on with the secure part of the sd, wiping out the card.
Good Luck
