How to recover data from sd card after format​？

From capturing precious moments with our cameras to storing crucial documents on the go, these compact storage devices are invaluable. However, one of the most common mishaps that users encounter is accidentally formatting an SD card. The thought of losing cherished photos, important files, or irreplaceable data can be daunting. Thankfully, formatting an SD card does not always mean that your data is lost forever.

Formatting an SD card is the process of preparing it for use by the operating system. This action typically involves creating a new file system, which organizes how data is stored and accessed on the card. There are two primary types of formatting:

Quick Format: This method removes the file allocation table, which keeps track of files stored on the card. Although it clears the directory structure, the actual data remains on the card until it is overwritten by new data.

Full Format: This type goes a step further by scanning the SD card for bad sectors and overwriting the entire card with zeros. While this method is more thorough, it significantly reduces the chances of data recovery.

Why Does Data Loss Occur?

Data loss can occur due to various reasons, including:

Accidental Formatting: A user may inadvertently select the format option instead of another action.

Corrupted File System: An SD card may become corrupted due to improper ejection, power failures, or software errors.

Virus Attacks: Malicious software can corrupt files and lead to loss of data.

Physical Damage: Dropping or exposing an SD card to extreme conditions can make data inaccessible.

What to Do Immediately After Formatting

If you realize that you’ve accidentally formatted your SD card, follow these steps to maximize your chances of recovery:

Stop Using the SD Card: Immediately cease any activity on the card. Avoid writing new data to it, as this can overwrite the old files.

Check for Backups: Before attempting recovery, check if you have any backups of your data stored elsewhere (cloud storage, another device, etc.).

Avoid Full Formatting: If you haven’t yet performed a full format, don’t. Stick to trying to recover from the quick format.

Assess the Situation: Take note of what data you lost and how critical it is. This assessment can guide your recovery efforts.
