1. Understand the principle of SD card data recovery
The basic principle of data recovery is to re-establish the state of storage before data loss. For SD card data recovery, we need to understand its storage mechanism and the reasons for data loss. Generally speaking, the storage unit of an SD card is divided into multiple areas, including the main storage area, the file allocation table area, the file directory area, and the reserved area. When data is deleted, only the relevant file directories are deleted, while the actual data remains in the primary storage. So, we can try to recover lost data by scanning these areas and re-establishing files through SD card data recovery software.
2. Choose the right SD card data recovery software
There are a lot of SD card data recovery software to choose from in the market. When choosing a software, it is recommended to prefer professional data recovery software that offers free scanning and preview features, such as Cloud Knight Data Recovery (the files can be previewed normally after scanning, that is, what you see can be recovered). This is a good way to estimate the recoverability of your data and avoid paying fees if recovery is not possible. In addition, you can also read the instructions of the software carefully before going to the official website of the software to ensure the correct operation.
Part 3: Steps to recover SD card data
- Stop using the SD card
Once you find out that your SD card data is lost, the first thing to do is to stop using the card. Because continuing to use the SD card may cause the data to be overwritten, which increases the difficulty of recovery.
- Download and install the software
Choose a software that is suitable for your computer system and download and install it, for example, Cloud Knight Data Recovery software is suitable for XP/Win7/Win8/Win10/Win11 operating system.
- Connect the SD card and scan
Remove the SD card from the device in the powered off state and connect it to the computer via the card reader. Run the software, select "USB flash drive/memory card recovery" according to the prompts, and select the SD card that can be recognized normally for scanning.
- Find and preview data
The results are automatically listed after the quick scan ends, and if you don't find the data or you're not satisfied with the preview results, you can select Deep Scan to retrieve more and more accurate data, but the scan will take longer.
- Export the required data
Finally, check the data you want to recover, and then click the "Recover Now" button to save the recovered data on your computer or other storage device for viewing.
4. Preventive measures
In order to avoid SD card data loss, the following precautions are recommended:
Back up your data regularly: Back up your important data from your SD card to your computer or other storage devices just in case.
Use genuine software: Avoid using software from unknown sources to avoid data loss due to viruses or malicious programs.
Operate with caution: When operating the SD card, be cautious about every step to avoid accidentally deleting or formatting the SD card.
Protect the SD card: Avoid exposing the SD card to harsh environments such as high temperature and humidity to avoid damaging the memory chip.
5. Related Questions and Answers

Q2: How to back up data before SD card formatting?
Insert the SD card into your computer or other device, and then copy the files from the SD card to the storage location of your computer or other device.
