Fujifilm X-PRO2: Memory Cards Myth

category: Cameras • 2 min read

This applies to all digital cameras including: Fujifilm, Canon, Nikon, Sony…

Myth #1: Do not erase images from the camera

Deleting images while reviewing is supposed to corrupt the memory card. Why don’t you try it yourself:

  • reformat the card in the camera
  • take a dozen photos of whatever is in front of you, your window, your desk, the wall…
  • start reviewing the images and delete image #3, image #5 and image #8. This means that there are 9 images left on the memory card
  • turn off the camera
  • insert the memory card in the reader attached to your computer
  • review the images and delete image #2 and image #6
  • unmount/safely remove the memory card
  • place it back into your camera
  • review the images with the playback

And guess what? It still works.

Myth #2. Format the memory card in the camera and not on the computer

Formatting on the computer is supposed to render the memory card unreadable by the camera.

All current cameras (that I know of) use FAT32 as a file system. In the ldquo;good old days” it was FAT when the memory cards were smaller than 2GB. By using the FAT32 file system, the maximum file size is 4GB and the maximum partition size is 2TB.

In the menu system of the Fuji: USER SETTINGS > FORMAT

The camera overwrite the existing FAT32 and creates the directory DCIM. All files on the memory card have been “quick erased”, which means, the directory entry for the various files have been deleted nut the image is still on the memory card.

If you format the memory card on the computer, the camera will create the DCIM directory for you.

Why don’t you try it yourself:

  • On your computer reformat the memory card
  • unmount/safely remove the memory card
  • place it back into your camera
  • take a few pictures
  • views them on your computer: they will be within the DCIM\FUJI_999 (3 digits starting with 100) folder

  1. Do NOT fill the memory card completely. Many cameras don’t know how to recover from a memory card full, so some of the file system will get corrupt.
  2. Let the camera finish the writing to the memory card before removing the card from the camera. Usually there’s an orange light that’s blinking while the camera is writing to the memory card.
  3. Don’t let the battery charge go too low or there won’t be “enough juice” to finish writing the images to the memory card and the memory will become corrupt.
