I shot my first wedding this weekend and found out I have a corrupt memory card, I'm a little unhappy at the moment. One of the cards I used is completely blank. I put it in the computer this afternoon to find out that it has 7.8 gigs available (8 gig card). Is it possible to recover any of the images. I have a mac and don't want to pay for any software without getting some he advice first.
Some more info:
I viewed the images on a computer before just to check a few of them. The card was safely ejected. A few weeks ago I was doing some ISO testing with my camera (so wasn't planning to keep the images). I viewed the images on my computer and safely ejected that card. I went back to the card a few weeks later to format it(for the wedding) the images were gone. I figured i just did it after I viewed them the first time. After this happened I'm wondering if the card should be trashed after sorting out the latest problem or if anyone knows what might be causing it. The images weren't viewed on the same computer each time that caused the possible corrupting so don't think the computer contributed (and went through the same process with 3 other cards).
Any help would be much appreciated. Thanks!
