Accidental deletion or drive formatting are the two leading causes of data loss. Let it be an internal drive or an external storage device such as an SD or a compact flash (CF) card, accidents do happen and might leave you teary-eyed. These days most of the professional cameras come with an SD or CF card slots for storing the captured photographs; this allows the user to store large amounts of data (especially in the case of CF cards). When you delete a file or a folder, in the file index, the space occupied by that folder/file will be marked as empty, so that new information can be written on it. Formatting is similar to deletion in a sense that formatting erases all of the data on the drive, all at once.

The system usually does not overwrite on the space which was previously taken by a now-deleted file; it merely marks that space as ‘available.’ The system will never overwrite on this ‘available’ space unless it runs into low disk space; in that case, only it will overwrite on this ‘available’ space. Till that, there is always a scope for the recovery of deleted data.

Common reasons for data loss from CF cards

  • Accidental deletion: It is one of the reasons for data loss. Sometimes the deletion can be intentional too. And formatting of the drive is another reason for the data loss.
  • Improper handling of the device: A physical damage to the device in which the memory card is inserted can in-turn harm the memory card. Additionally, memory card running out of space and operating the device even when the battery is low can be blamed for data loss in some situations.
  • Firmware damages: You may have received a faulty memory card from the vendor itself. Some firmware damages can be the result of virus or a malicious attacks also.
Some precautions against CF card data loss
  • For severely damaged or file system corrupted CF cards, Windows might prompt you to format the CF card in a failed attempt to read and access the data on the card. Please ignore the message and do not format it before you recover your photos.
  • Once you discover about the damage, avoid overwriting the card (means, do not take pictures with the same memory card before the recovery).
