Well the problem with my brothers card is, that it doesn't have any branding on it. I just thought of the possibility that it might be somewhere on the card along with the programs, so I am going to ask him about that. I have used transcend cards and others, I don't remeber the brand of. Now you mentioned it, I do remember that they all had some switch on the side to lock them. So that is definitly not what I am going to look for from now on.
If I get lucky and find a card I'll be sure to let you know. I hope you still will let me know if you find a card that works.

Kind regards again,
Willem.
