Missing pics on SD card
Discussion
I took some photos for a performance recognition event at work yesterday. I've got a Canon 60D and an unbranded 32GB SD card (probably the problem). I shot in RAW/ and JPEG. Took about 150 photos then later in the afternoon the message 'cannot display image' appeared on the playback screen. I was really worried that I lost a lot of photos. After the event I went outside and took some pics of the grounds.
The first 150 or so images have downloaded onto my PC and the outside images are also there but not the ones in between. Are these images gone forever or can I retrieve them with some software? They are not as important as the presentation ones (thankfully they are on there!) but it would be nice to know what happened and if they are on there. Is the card or sections of it corrupted?

I've had this on Compact Flash cards before. Recovery software said the pics were corrupted.
I was given advice to always format the card between uses instead of deleting the files and it's not happened since.
Previously I was using a Canon 20D and a CF card, never had a problem. I formatted the SD card as soon as I bought it. I was given advice to always format the card between uses instead of deleting the files and it's not happened since.
If you feel the experience might be useful try some recovery software to see what it can find.
The chances are that the files are not corrupt but the card's index, which keeps track of the file fragments, might be.
Recovery software tends to assume that the indexes are stuffed and then discovers what fragments there are while attempting to rebuild what should have been there.
Worth a try if only for the experience.

Sorry to hear you're suffering grief over this, but at least you managed to retrieve the vitally important images.
Try something like www.isobuster.com which has been around for years and has been steadily improved to keep up with changing formats.
Using cheap unbranded SD cards is always a recipe for disaster, for what SD cards cost nowadays it's just not worth the hassle.
EDITED to add that you can test the SD card with h2testw.exe: http://www.heise.de/download/h2testw.html
