Q. Should I fill up a memory card (CF or SD) with images before I delete the images or reformat the card? I'm thinking of the VCR and audiocassette days, when if you recorded over and over on one portion of a tape, it would wear out that portion before the rest of the tape.
A. Memory cards don't copy over the same space over and over as a tape would. A more pressing issue: If you fill up the card with images, you run the risk that, if the card becomes corrupted, you will lose that many more images. Also, if you're out shooting with a nearly full card, you'll find yourself scrambling to erase images to make room for others. Given that the price of memory cards has dropped enormously in recent years, and that you can reformat them many thousands of times without a problem, we say buy a bunch of them, offload your cards at the end of the day, and reformat them.
