Suppose, you were your press's only photographer who photographed a terrorist attack of a hotel in the city a few minutes back. This incident being of national interest is of great importance. Proud of your skillful sure and striking shot, your office is now greedily awaiting your enlightening photos. Back at office, you are startled to find your memory card empty. That is really shocking as a man and shameful as a professional.

Cause:

If you used a wholesome and compatible card when taking the photos, any of the following may have caused this mysterious loss:

1. unmindfully deleting the photos,
2. unmindfully formatting your card,
3. removing the card from camera while you were reviewing your shots,
4. contact error,
5. switching off the camera or unplugging USB while you were previously transferring the photos, etc.

Solution:

If deletion or formatting caused the problem, running a data backup program may recover your self-esteem and professional dignity. If contact error is not the issue, any of the last two possible causes above must be responsible. Now, reformat your card to make it usable again, and then run the data backup program. But in all cases, you should avoid writing any data on the reformatted card before recovery not to risk your photos' getting overwritten. Overwritten data cannot be recovered.

If the problem persists, use some specially Digital memory card recovery software.
