As various mobile electronic devices such as smartphones, tablets, digital cameras, and driving recorders have entered thousands of households, SD cards have also gained widespread market recognition as a storage medium matching these devices. SD cards have gradually become an indispensable data storage tool in daily work and life due to their small size, large capacity, high reading and writing speed, and compatibility with a variety of devices. Here, we discuss in detail whether data can be recovered after SD card formatting and how to recover lost data.
1. Can the SD card be recovered after it is formatted?
In daily use, SD cards not only store office files, but also carry a large amount of personal memories, such as precious photos, videos, and music. SD cards generally have a read and write life of about 100,000 times. Without physical damage, they may still fail due to a variety of unforeseen reasons. These reasons include but are not limited to frequent access to unfamiliar devices, forced power-off and card removal, or partial oxidation or damage of the gold finger. Once the logical file of the SD card is damaged, most devices will prompt you to "format".
Many people worry that all data in the SD card will be lost once they follow this tip and format it. However, this is not the case, because the so-called "formatting" only adds a "deletion mark" to the beginning of the SD card sector so that the system can write new data. The original data is actually still stored inside the SD card and can be recovered by using professional data recovery software such as EasyRecovery.
EasyRecovery data recovery software developed by American Ontrack company uses deep scanning technology to easily recover files in various formats from SD cards to other storage media. Therefore, you don’t have to worry too much about data loss after formatting the SD card.

2. How to recover lost SD card data
When the device cannot recognize the SD card or accidentally deletes important files, the most critical thing is to immediately stop any writing operations on the SD card to avoid new data overwriting the original data, making the files unrecoverable.
First, connect the SD card to the computer through a card reader, and then visit EasyRecovery’s official Chinese download website to download and install the software. After successful installation, follow these three steps:
Step 1: Start the EasyRecovery software, select the data type that needs to be recovered, and find the target SD card in "Connected Hard Drive".
Step 2: Start the scanning program, and the software will automatically list the recoverable files in the SD card.
Step 3: Select the files that need to be recovered in the "File Type" list and click Recover.
In this way, you can easily recover lost data from the SD card.
