Recover photos from a damaged card

While we're on the subject of SD cards, let's talk about photos. A new, high-capacity SD card ? smaller than a postage stamp ? can hold thousands and thousands of photos. It's a photographer's dream.

Of course, if the card breaks, it becomes a photographer's nightmare. That's why I recommend taking a number of smaller SD cards on a trip. If one breaks or gets lost, you haven't lost as many photos.

Then there are times when a memory card just goes haywire. You put it in the computer and it shows up blank, it's corrupt or just missing files.

If your card reader isn't broken and the card isn't externally damaged, you have a bad card. But hope is not lost.

Grab a free photo recovery program. Zero Assumption Recovery and Recuva are two good ones.

Tip inside of a tip: These free file recovery programs find hidden or deleted items on memory cards. You can use them to recover files on flash drives and hard drives as well.

After a scan, you might see your photos and other missing files. When you recover the files, be sure to save them to your hard drive. Don't try to save them to the memory card!

Not only is the card dying, you'll overwrite the files you're trying to recover. Trust me; it doesn't end well.
