High chance to recover files/formatted files from Memory Card


Have you ever accidentally formatted your SD with important files in it without backup? Or perhaps your hard drive crashed when you transfer files or images from memory card to computer? What's the chance to recover and retrieve lost files from memory cards.

Chance of Recovery is high to retrieve deleted files from memory card

If you manually deleted images from the card either on the camera(CF Card, SD Card, SDCH Card, etc) or on your PC, the chances of recovering all data are very high, as long as more images or data were not written on the disk. Just like in formatting, deleting files simply marks certain area of the disk as free for writing. The actual files are never erased from the disk. (Download File Recovery)

Chance of Recovery is high to recover files from formatted card

if you happened to format the memory card for whatever reason, either in-camera or on your PC. Chances of recovering all data are very high, as long as the card was not touched after the last format. This is due to the fact that the formatting process never actually deletes the images from the memory card – it simply labels the card as “free” and prepares it for writing.

Chance of Recovery to recover data due to Non-physical damage/data failure 

The chance to recover photo to data failure is Moderate to Low, depends on type of failure. Whether you are using a Compact Flash or SD/SDHC card, one of the more common ones is when a memory card fails during the process of writing images to the card (corrupted data). This is where your camera would give an error, indicating that the data could not be written to the card. The chances of data recovery are moderate to low, depending on how serious the damage is due to bad sectors, etc. Some unreadable cards can be recovered, again, depending on the damage.

Chance of Recovery is low to recover lost file from physical damaged card

If your memory card has suffered from physical damage and is unreadable, the chances of recovery are very low. You could try H-Data Recovery Master if it can recover anything. If all programs fail and the drive cannot be recognized, it might be better to take it to data recovery experts, who can try to retrieve the data in a lab environment.
