Nikon cameras use NEF (Nikon Electronic Format) RAW format to store photos. These RAW photos contain all the information captured by the camera's sensor, and hence are very important. An NEF file is written to a memory card in either compressed or 'lossless' compressed form. But, these NEF files may become become inaccessible in event of memory card corruption. A minor mistake while handling a memory card can give rise to grave data loss situations. Therefore, it is highly suggested to take regular backup of NEF photos. However, if you face a data loss situation, in absence of a valid backup, no need to worry. In such situations, you can easily go for a photo recovery software.

Consider a scenario, wherein, you have a Nikon camera which stores photos in NEF format. One day you decide to transfer photos from your camera's memory card to your computer. You connect both the devices and while the transfer process is on, your camera shuts down all of a sudden after experiencing a battery loss.

The next time when you insert the card in your Nikon camera, it displays an error and renders all your pictures inaccessible.

Cause

The abrupt behavior is an outcome of interruption in the read/write process. In the above case, the memory card become corrupt after the write-process was halted unexpectedly. The interruption in read/write process could also occur in many ways, some of them are listed below:

• When the memory card is pulled out of the camera while it is still on

• When the memory card is removed from the camera while transfer process is on

• When the camera shuts down unexpectedly while it is in the process of writing a photo

• When the camera is switched off immediately after clicking photos

In all the above cases, there are high chances of memory card becoming corrupt, thus leaving photos inaccessible.

Resolution

In you are facing problems with a card, you must try and take backup of the photos stored onto it. After taking backup, you must format it in the Nikon camera. Formatting installs a new file system on the card, making it reusable.

In order to recover lost NEF photos, you should either look up to a backup or an efficient photo recovery software. Though, you have lots of options available on the Internet, ensure you download a software which recovers NEF files. Also, ensure that you use a read-only photo recovery utility.
