Data loss from a Pc, laptop, memory card, or an iPod can have serious implications. The gravity of the issue is directly proportional to the kind of data you have lost. There are two ways to address this problem. You can whether recreate the data, or recover the lost data. Recreating the data will depend on the complexity, or the kind of data that you have lost.

- the cable is pulled off while transferring data from the camera to Pc or laptop
- you have accidentally deleted the data from the card
- you have formatted the card
- there is an improper shut down of the principles due to power fluctuations or software malfunction
- the backup is corrupt or incorrect backup practices
Photo rescue software to recovering lost Raw, Jpeg or Tiff files
Even after losing data from the memory card (Sd, Mmc, Smart media, Miniature), you can still recover it with a specialized photo rescue software. When data is deleted from the memory card, the data do not get erased completely, but the pointers to the data are erased. This makes the data inaccessible. Specialized photo rescue software is enabled with suited algorithms to trace and recover such data.
However, if you use the camera to shoot more pictures after deleting data, the chances of recovering deleted or lost data is less. This is because the new pictures will over write the lost or deleted data. So, immediately after you lose data from a card
- do not use the card to store more data till you recover lost data
- remove the card from the camera and store it in a safe place to avoid using it supplementary till you recover lost data
