While I use a K-x, this problem seems to affect more than just my camera model or brand of memory card (Kingston, class 4).
- When trying to view the preview of my photos in-camera, some photos do not display, instead showing an “Image can not be displayed” error (or something to that effect). There was previously a “Memory Card Error” messaged displayed in the camera.
- When imported, these files are corrupted and do not display or import.
- Attempting to format the card in-camera produced the same “Memory Card Error” message.
The solution: Use your USB cable to connect the camera to the computer for importing, etc., instead of inserting the SD card into the computer directly. Then eject the camera from the computer and format the SD card through the camera’s menu.
This solved the problems listed above, for me.
Based on what various Pentax forum posters say, the mistakes that led to the problem appear to be any mix of the following:
- not formatting the card in-camera before using it;
- plugging the SD card directly into the computer for importing;
- deleting photos from the card while it is plugged directly into the computer;
- deleting photos in-camera.
