A few weeks ago I was doing a Photography Shoot for a Company and had to be onsite to take photos of some volunteer companies that were contributing to the project. I ended up taking some 90 or so shots. It was until a day later I got to look at them to process them for the customer. When I inserted the memory card into my card reader, my heart sunk, I got a normal response, no photos found. I am like What??? Panic hit me, my heart is racing, now what! Most of my memory cards for both my cameras are Lexar. I have a few Sandisk but mostly Lexar. I as my panic started to subside I remembered that my Lexar Professional cards each came with a piece of paper that I had filed away for a rainy day. I oddly remembered where I had filed them and wow, on that paper there was a download link to download file recovery software for the cards and the license was on that paper as well. So I downloaded that software for both my windows laptop and my mac and installed it on both.
I inserted the card and ran the recovery software and I was able to easily recover ALL the files with no effort. I also noticed that many of the files I had since discarded which I thought when you format your memory card in your Camera they would be gone. Nope, even those files were there. So not sure what format memory card really means in the camera. Anyways I recently came across an article at slrlounge.com about how to minimize memory card problems. This article has some good points on keeping your memory cards healthy. Just click here for more info on minimizing memory card problems.
