Data Recovery After SD Card Formatting on Sony A7III

Many people turn to data recovery software to retrieve lost files after accidentally formatting their SD card, hoping to recover precious photos and videos. While some of these software solutions boast user-friendly interfaces and high success rates, we do not recommend relying solely on them.

In some instances, these programs fail to recover the data, regardless of their reliability. Specifically, for the Sony A7III camera, it is virtually impossible to recover the formatted data using any online software. This case study delves into our approach and techniques for achieving successful data recovery in such challenging scenarios.

Formatting an SD Card on a Camera

It is easy to format the SD card on the camera. With a few clicks, you can clear and prepare the SD card to store new data. However, this convenience comes with a risk. Accidental formatting of the SD card erases all data stored on it, including photos and videos that have not been backed up.

Most regular cameras format the card by only erasing the beginning and putting in a new file system, which can be undeleted. On the other hand, the Sony A7III formats the card by zeroing out the translator; this is a unique feature because it starts the card as a clean and empty sector.

If you accidentally format the SD card on other cameras, you may be able to recover the data using readily available software solutions. However, this can be risky, so it is better to rely on proven data recovery services. Check our DIY recovery risks post.

How Sony A7III Formatting Works

In contrast, if you format the card on your Sony A7III camera, using standard data recovery software will not help at all. When a Sony camera formats an SD card, it does a special process that basically makes the card look empty. Even though the data is still there, the camera and other normal programs can’t see it.

This makes it really hard to get the data back if something goes wrong. Knowing this is important if you need to get your data back because regular ways of recovering files might not work. You might need more advanced methods to help you out.

Evaluation of Formatted SanDisk SD Card in Cleanroom

Once we received the SD card, our team immediately began evaluating it. We performed a physical analysis to determine the extent of the formatting and any other potential damage.

Upon further examination, we found that the SD card had no physical damage and was only formatted by the Sony A7III camera. This meant that the data was still present on the card but needed specialized techniques for recovery. Thanks to our previous experience and knowledge of Sony A7III formatting, we were confident that we could retrieve the lost photos.

Data Recovery Process of SD Card Formatted on Sony A7III

We took the SD card into our cleanroom facility, where we used specialized equipment and techniques to retrieve the data. Our team carefully connected the SanDisk SD card to our proprietary recovery system.

Using our advanced software, we tried to locate the data logically. However, the Sony A7III formatting process made it difficult to do so. Only zeros were visible, and the file system was completely hidden.

Then, we carefully removed the protector film where the memory pads are located. After removing the chips, we used a specialized NAND adapter to connect them to our system. This allowed us to read the raw data stored on the chips without any interference from the Sony A7III formatting.

After hours of thorough work and careful recovery techniques, we were able to retrieve all the raw data from the NAND chips. We then used our specialized software to reassemble the data and recover all the lost photos.
