How to recover formatted sd card?

Recovering data from a formatted SD card can be a daunting task, especially if you don’t know where to start. However, with the right approach, tools, and techniques, it’s possible to recover lost files. 

1. SD Card Formatting

1.1 What is Formatting?

Formatting an SD card involves preparing the card to store data. This process can include creating a file system (FAT32. exFAT, NTFS, etc.), which determines how data is organized on the card. When you format a card, the system erases the data structures (the index) that point to the data, making it appear empty. However, the actual data may still reside on the card until overwritten by new data.

1.2 Types of Formatting

Quick Format: This option only deletes the file index and not the actual data. It’s faster but leaves the data intact, making recovery easier.

Full Format: This option deletes the file index and overwrites the data, making recovery significantly harder and, in some cases, impossible.

2. Preparing for Data Recovery

2.1 Stop Using the SD Card

As soon as you realize your SD card has been formatted, stop using it immediately. Continuing to write new data can overwrite the sectors where your old files were stored, significantly reducing your chances of recovery.

2.2 Assessing Your Recovery Options

You have two main options for recovering data from a formatted SD card:

Software Recovery: Use specialized data recovery software.

Professional Services: If the data is critical and software recovery fails, consider professional data recovery services.

3. Using Data Recovery Software

3.1 Choosing the Right Software

When selecting data recovery software, consider the following:

Compatibility with your operating system (Windows, Mac, etc.).

Types of files supported (photos, videos, documents, etc.).

User reviews and success rates.

Availability of a free trial version.

3.2 Recommended Data Recovery Software

Here are some popular recovery tools:

Recuva: User-friendly and effective for Windows users.

EaseUS Data Recovery Wizard: Comprehensive recovery options for both Windows and Mac.

Disk Drill: Powerful software for both Windows and Mac that supports a variety of file types.

PhotoRec: Open-source tool that works with multiple operating systems, focusing on recovering lost files from storage devices.

3.3 Step-by-Step Recovery Process

Follow these steps to recover data using software:

Download and Install the Software: Choose your software and install it on your computer. Do not install it on the SD card to avoid overwriting data.

Connect the SD Card: Use an SD card reader to connect your formatted card to your computer.

Launch the Recovery Software: Open the installed software and select the SD card from the list of available drives.

Select the Recovery Option: Choose the type of recovery (e.g., deep scan) for a more thorough search for lost files.

Scan for Lost Files: Initiate the scanning process. This can take time depending on the size of the card and the method used.

Preview the Recoverable Files: Once the scan is complete, review the files that can be recovered. Most software allows you to preview files before recovery.

Recover the Files: Select the files you want to recover and choose a location to save them. Always save recovered files to a different drive to prevent overwriting any remaining data on the SD card.

5. Tips for Successful Recovery

5.1 Use the Right Tools

Always use reputable data recovery software to ensure the best chance of recovering your files. Read user reviews and consider trial versions before purchasing.

5.2 Avoid Writing New Data

As mentioned earlier, writing new data can overwrite the old files. Ensure no new files are added to the SD card after formatting.

5.3 Regular Backups

Regularly back up your data to prevent loss in the future. Use cloud storage or external hard drives for backup purposes.

6. Preventing Future Data Loss

6.1 Proper Ejecting
