How to extract deleted files from sd card？

SD cards are widely used in devices like cameras, smartphones, and tablets for storing photos, videos, and other files. However, data loss can occur due to accidental deletion, formatting, or corruption. Understanding how to recover deleted files from an SD card is essential for anyone who relies on this storage medium. 

SD Card Data Loss

Common Causes of Data Loss

Accidental Deletion: Files can be mistakenly deleted by the user, leading to loss of important data.

Formatting: Formatting an SD card erases all files. Users might format their cards without backing up data.

Corruption: File system corruption can occur due to improper ejection of the card, power failure, or malware.

Physical Damage: SD cards can be damaged by exposure to water, extreme temperatures, or physical stress.

Importance of Immediate Action

When files are deleted, they are not immediately erased from the storage device. Instead, the space is marked as available for new data. If you continue to use the SD card, the chances of overwriting the deleted files increase, making recovery difficult. Therefore, taking immediate action is crucial.

Preparing for Recovery

Steps to Take After Data Loss

Stop Using the SD Card: Immediately stop using the card to prevent data overwriting.

Remove the Card: Eject the SD card from the device to avoid any accidental writes.

Assess the Situation: Determine the cause of data loss to choose the appropriate recovery method.

Using Recovery Software

Select a recovery tool based on your needs and the features offered. For this guide, we will use Recuva as an example.

Step 2: Download and Install

Visit the official Recuva website.

Download the software and install it on your computer. Ensure you install it on a different drive than the SD card to avoid overwriting data.

Step 3: Connect the SD Card

Insert the SD card into the card reader or directly into your computer.

Make sure the card is recognized by the computer.

Step 5: Scan the SD Card

Click on “Start” to begin the scanning process.

Recuva will scan for deleted files. This may take some time, depending on the size of the card.

Step 6: Preview and Recover Files

Once the scan is complete, Recuva will display a list of recoverable files.

Preview the files to find the ones you wish to recover.

Select the desired files and click on “Recover.”

Choose a destination folder on your computer to save the recovered files. Avoid saving them back onto the SD card to prevent overwriting.

Manual Recovery Methods

In some cases, manual recovery might help, especially if the files were deleted recently.

Check Recycle Bin: If the SD card was connected to a computer, check the Recycle Bin for accidentally deleted files.

File History or Backup: If you have a backup system in place, check to see if the files are stored there.

Tips for Successful Recovery
