I took some pictures yesterday with a new card and there was one corrupt file - is my camera at fault? What causes this? I do remember switching from RAW to JPG in the middle of shooting yesterday, does that cause corrupt files?
Your help is appreciated!

1. Reformat your card regularly using your camera software as that will help to prevent data corruption. If you need to rescue files try ‘photo rescue’ software.

   No, switching formats mid shoot should not cause any problems. If they persist you may have a camera problem, possibly with the firmware… sometimes it can be a problem with bad sectors on an old disk.

2. V is right.

   There are two other possible cause of corruption.

   * deleting images in the camera, rather than waiting until the images are on your computer.
   * removing or inserting the card while the camera is turned on.

   Formatting after each use is the only way to keep your card refreshed (new file folders and a new image index file) and ready to be uses for your next shoot. Memory cards have limited lifetime warranties and are designed to perform well with up to 20,000 formatting cycles. If formatting does not correct the problem, contact the card maker and request a replacement.
