Ohhhhh - I can see that might be a problem.

I was thinking about this after I posted. The thing to do would be to do a test. I would format the card and then see what can be recovered with file recovery software. Then I'd format it again and take a bunch of photos with the lens cap on to see if that displaced all the old data. I think if you filled the card with black photos, or even filled it with a bunch of huge, useless Photoshop files, that would effectively bump the old image files. But you'd need to test to see if it worked.

There probably is a way to completely wipe a drive or card clean. I would ask IT experts about that. In fact, I'll check with my IT guy here at the office and see if he knows anything.
