So Im getting rid of a couple memory cards I used in my 1D Mark IIn (which I traded off, btw). I am trying to completely wipe the media so that the pictures on the memory cards cannot be recovered. I have the Sandisk Rescue Pro but its not working. Everytime I use the media wipe feature it fails, has an internal error, or just doesnt do aynthing everytime i try.
So here I am, asking if anyone here has any programs they can suggest I use before I ship off my camera + memory cards in ~12 hours.
Please let me be clear that I dont think the buyer will steal my work or anything, its just that there's family photos and personal photos Id rather not anyone but myself to have.
