Fix Canon Memory Card Errors

Fix Canon Memory Card Errors

1. Err 02

Error 02 means that the camera can't get to the SD card because it's broken or not connected correctly. This mistake means there might be a problem with the SD card or how it was put into the camera. Usually, it's because the card is broken (cracks or bends) or the link isn't safe.

Solution:

  • Cracks, bends, and scratches on the SD card should be considered. If you need to, replace the SD card.
  • Ensure the SD card is properly put into the card slot on the camera. Remove it and return it to the card to make a secure link.
  • Get rid of any dust or dirt on the metal contacts on the SD card and the card port on the camera with a dry, soft cloth.

2. Err 03

Error 03 means there is a problem with the folder layout on the SD card, which can happen if there are too many folders. This mistake means the directory structure is too complicated, making it hard for the camera to move around in the storage. By improving the folder structure, you can ensure that everything runs more smoothly and stop Error 03 from happening again.

Solution:

  • Connect the memory card to a computer and change the folder layout by cutting down on the number of folders or levels of nesting.
  • To make the directory layout easier to understand, remove folders that aren't needed or move files to fewer folders.
  • It is important to ensure that the SD card doesn't have more groups and files than the camera can handle.

3. Err 04

The error code 04 means that the SD card has run out of space on it. This error happens when there isn't enough room on the card to hold more files. Please remove the files not needed on the SD card or move them to another storage device to fix the problem. With enough storage, you can keep taking pictures without stopping, giving you a more uninterrupted shooting experience.

Solution:

  • To make room on the SD card, remove things you don't need or move them to a computer.
  • If you often run out of storage room, consider using an SD card with more space.
  • Ensure you check the SD card's free space often to avoid running out of room while shooting.

4. Err 10

Error 10 means there is a problem with a data file, which could mean that the file system is faulty, incompatible, or not present. This mistake shows up when the camera has trouble reading or getting to the files on the SD card. Update the camera's software regularly to fix any compatibility issues and keep it running at its best.

Solution:

  • Use the camera's formatting to create a new SD card file system and fix corruption problems.
  • Ensure the SD card has a file system that works with the camera, like FAT32 or exFAT.
  • Make sure that your camera's firmware is up to date. File system compatibility problems may be fixed in newer firmware releases.

5. Err 99

Error 99 stops the camera from taking and could mean problems with the SD card or lens connection. This error stops shooting, which could be because of a problem with how the camera talks to either the SD card or the lens. Putting a different SD card into the camera can help determine if the card still causes the mistake.

Solution:

  • Take out the SD card and look for damage or dirt on the contacts. Clean the contacts, then put the card back in firmly.
  • Ensure the lens is attached correctly to the camera and that there are no things in the way of the lens and the camera body communicating properly.
  • Try the camera with a different SD card to see if the problem still happens. If it does, you should get more help from Canon support.
