How to recover deleted items from sd card？

​Losing important files from an SD card can be a frustrating experience, whether it’s due to accidental deletion, formatting, or corruption. Fortunately, recovery is often possible with the right approach and tools. This comprehensive guide will walk you through the steps to recover deleted items from an SD card, including preparation, software options, and recovery techniques.

1. SD Cards

1.1 Types of SD Cards

Secure Digital (SD) cards come in various types: SD, SDHC (High Capacity), and SDXC (Extended Capacity). Each type has different storage capacities, and understanding these can help in selecting the right recovery approach.

1.2 How Data is Stored

Data on an SD card is stored in a series of blocks. When files are deleted, the data isn’t immediately removed; instead, the space is marked as available. This is why recovery is often possible if the space hasn’t been overwritten.

1.3 Common Causes of Data Loss

Accidental deletion

Formatting the SD card

Corruption due to improper removal

Physical damage

Virus attacks

2. Preparation for Recovery

2.1 Stop Using the SD Card

The most crucial step after data loss is to stop using the SD card immediately. Continuing to write new data can overwrite the deleted files, making recovery impossible.

2.2 Check for Backups

Before diving into recovery software, check if you have backups on other devices or cloud storage. If a backup exists, restoring from it can be a simpler solution.

4. Step-by-Step Recovery Process

4.1 Install the Recovery Software

Download and install your chosen recovery software on your computer. Ensure that it’s from a reputable source to avoid malware.

4.2 Connect the SD Card

Insert the SD card into your computer using an SD card reader. Ensure that the card is recognized by the system.

4.3 Scan the SD Card

Open the recovery software and select the SD card from the list of available drives. Start a deep scan for better results, as it searches through all sectors.

4.4 Preview and Recover Files

Once the scan is complete, the software will display a list of recoverable files. Preview the files to confirm they are the ones you need, then select and recover them to a different storage device to avoid overwriting.

5. Manual Recovery Techniques

If software recovery doesn’t work, you can try manual techniques.

5.1 Using Command Prompt (Windows)

Open Command Prompt as an administrator.

Type chkdsk X: /f (replace X with your SD card drive letter).

Press Enter. This command checks for file system errors and attempts to fix them.

5.2 Using Terminal (Mac)

Open Terminal.

Type diskutil list to find your SD card.

Use sudo fsck_msdos /dev/diskX (replace X with your SD card number) to check and repair the file system.

6. Post-Recovery Tips

6.1 Create Regular Backups

To prevent future data loss, implement a regular backup schedule. Use cloud storage or an external hard drive to keep copies of important files.

6.2 Properly Eject the SD Card

Always eject the SD card safely using the operating system’s eject feature. This prevents corruption and data loss.

6.3 Monitor SD Card Health

Keep an eye on the health of your SD card. Tools like CrystalDiskInfo can help you check for issues and prolong the lifespan of your card.
