Most of us may accidentally delete photos when viewing them. If you want to recover these deleted photos from the SD card, a piece of data recovery software can help you. In this essay, we will tell you why photos can be recovered and how to be recovered.

Part 1: Why Deleted Photos and Videos can be Recovered from SD Card

Through data recovery software, deleted photos and videos can be recovered from the SD card. Take photo files as an example. Most of software will adopt the header data when they are recovering the photos. So, what header data is?
In fact, each file is composed of header and payload, and the header records different data that defines the file type. That is to say, a header can be regarded as the unique “fingerprint”of a file.

If you view photos with the binary viewer, you will discover that “FILE0”, “IE C1” (marked on the below img.) are always seen but the arrangements and forms of these files are completely different. That can also approve that the headers are different between files.

The data recovery software can scan the fixed features of files to separate the deleted data from the existed data, and then it can recover the deleted one.

Part 2: Does and Don’t when SD Card Data is lost

Clicking “Delete” in the SD card does not mean the file will disappear forever. If you use the disk management software to scan the card, the software will scan out many blocks where data is be stored.
Like this image, green blocks indicate the data marked as deleted but not overwritten; normal data is placed in red blocks; blank blocks are free space for data storage.

Of course, we can copy, delete and format data in the SD card. These ways are merely to change the blocks to be writable. Once the files are deleted, we cannot get access to them along with the path on the operating system, but they still exist in the SD card. That is to say, deleting and formatting the SD card will make room for storage but not erase the written data.
However, if you overwrite data on these blocks, the original data will be covered and spoiled. Even though the partial data can be recovered, most of them are damaged or unable to be opened, shown as below:

All in all, you can recover data from the SD card as long as you never overwrite with new data. How to recover data from SD card safely and effectively? Go to the next part!

PhotoRec is recovery software for disks and zips. It works well on SD card, too. PhotoRec can skip the file system and recover data from the blocks. Even though the file system has been severely damaged or formatted, it still works. It can also scan the known header to recover the complete file.
