recovering duff images

Last week i had the first instance of a dodgy memory card.

It was in my k200d and out of 200+ shots, five were corrupt. the odd thing is, they show up ok on image capture (on a Mac) and also on the screen on the back of the camera. when i tried to upload them to flickr they didn't go. they are taking up space on the cards equivalent to a good shot, but iphoto and pentax browser software says the file type isn't recognised.

any ideas or are the images gone?

cheers

The file header or file may be corrupt. What you are seeing in the Mac or camera screen is the small thumbnail JPG held inside the RAW or full size JPG file.

If you can see the file in the equivalent of file manager you could at least copy it to the PC/Mac and delete it from the card. You can then try working on it, opening in different apps &c where you might find that it works with one.

Does the 200D have in camera editing? ie B&W etc.

I would try something like that first and save it as a new image, I think I'm correct in saying if the camera cant edit the file then its probably a lost cause.

Yes, the K200D has onboard editing. See page 182 in the manual, Processing Images with Digital Filters.

However, if the file is corrupted it may not work. But try it by all means.

But try to save an off camera copy first ... If editing fails or deletes the file you still have one to go back to.

thanks guys.

I tried the in camera editing, but no joy.

i did transfer the files to the laptop, but can't open them, even with preview. looks like those 5 shots have been lost.

That's my first duff card, i get them from 7dayshop - usually get the unmarked ones, but this time went for some fuji ones - and never had a problem - that'll teach me to switch brands.

just taken some more shots to see if any of those die and i'll use a different card from now on.

thanks again.

Do you Format your cards ? As this needs to be done periodically to help avoid corrupted files.
