Reformat memory card for use in other cameras?

Hi. Presently, all my Sandisk Extreme Pro memory cards that I used with my BMPCC don't work with my other cameras, specifically a Panasonic HMC150. I use a Mac, and I've taken the cards into disk utility to try erasing, first aid, and reformatting in all the options available to me. Have these cards been rendered usable ONLY with the BMPCC?

I should mention that I'm aware that sdxc cards haven't worked with my other camera in the past, but I've done the firmware upgrade to it which addresses this issue. I've got 6 64GB cards that I can't use with other cameras...
