How to recover files from microsd card that won’t read​？

Causes of Micro SD Card Not Reading

Physical Damage: This can occur due to factors like improper insertion or removal, exposure to extreme temperatures, water damage, or physical impacts. For example, if the card is bent or the metal contacts are scratched, it may prevent proper reading.

File System Corruption: Viruses, sudden power outages while the card is in use, or improper ejection can lead to file system corruption. This can make the card appear unreadable to the device.

Software Issues: Outdated or incompatible drivers on the device reading the card, or problems with the operating system, can also cause reading failures.

SD Card Reader Problems: The card reader itself may be faulty. Dust, dirt, or mechanical issues with the reader can prevent it from establishing a proper connection with the Micro SD card.

Precautions Before Recovery

Avoid Further Writing: Do not save any new data to the Micro SD card. Any new data written to the card may overwrite the existing data that needs to be recovered, reducing the chances of successful recovery.

Handle the Card with Care: Avoid touching the metal contacts on the card to prevent static electricity discharge or physical damage. Use anti-static gloves if possible.

Backup Recovered Data: As soon as you recover the files, back them up to another storage device to prevent data loss in case of future issues with the Micro SD card or the recovery process.

Methods to Recover Files from Unreadable Micro SD Card

Method 1: Check and Clean the Card and Reader

Inspect the Micro SD Card: Examine the card for any visible signs of damage, such as cracks, bent edges, or dirty contacts. If there is dirt or debris on the card, gently clean it with a soft, dry cloth.

Clean the SD Card Reader: Use compressed air to blow out any dust or debris from the card reader slot. If the reader is external, you can also use a cotton swab dipped in isopropyl alcohol to gently clean the contacts, but make sure to let it dry completely before using it again.

Reinsert the Card: After cleaning, carefully insert the Micro SD card into the reader and check if it is recognized. Try inserting it into different card readers or devices to see if the problem persists.

Method 2: Update Drivers and Software

Update Device Drivers: For computers, go to the Device Manager and locate the SD card reader. Right-click on it and select “Update Driver”. Follow the on-screen instructions to update to the latest driver version.

Update Operating System: Ensure that your computer’s operating system is up to date. Manufacturers often release updates that include fixes for hardware compatibility and storage issues.

Use Compatible Software: If you are using specific software to access the Micro SD card, make sure it is updated to the latest version and is compatible with your operating system and the card’s file system.

Method 3: Check and Repair File System Errors

On Windows: Open the Command Prompt as an administrator. Type “chkdsk H: /f” (replace “H” with the drive letter of your Micro SD card) and press Enter. This command checks the file system for errors and attempts to fix them.

On Mac: Use the Disk Utility. Open Disk Utility, select the Micro SD card, and click “First Aid”. The utility will scan for and repair any file system issues.

Method 4: Use Data Recovery Software

Panda Assistant also includes additional tools to help users manage their data recovery efforts more effectively. For instance, the software provides a preview function, allowing users to view recoverable files before proceeding with the restoration process. This ensures that users can confirm they are recovering the right files, saving time and effort.

Security is a top priority for Panda Assistant, and the software is designed to prevent further data loss during the recovery process. It features a read-only mode to avoid overwriting data and ensures that only deleted or lost files are targeted for recovery.

Method 5: Seek Professional Data Recovery Services

When to Consider Professionals: If the above methods fail, or if the data on the Micro SD card is extremely important and valuable, it may be time to consider professional data recovery services. Professionals have specialized equipment and techniques to handle complex data recovery situations.

Choose a Reputable Service Provider: Look for companies with a good reputation and experience in data recovery. Check online reviews, ask for recommendations, and make sure the company offers a free evaluation and a clear price estimate before proceeding.

Tips for Preventing Future Micro SD Card Issues

Use Quality Products: Invest in high-quality Micro SD cards and card readers from reputable manufacturers. Quality products are more likely to be reliable and durable.

Eject the Card Properly: Always use the “Safely Remove Hardware” option on your device before removing the Micro SD card to avoid file system corruption.

Keep the Card and Reader Clean: Regularly clean the Micro SD card and the card reader to prevent dirt and dust from causing problems.

Backup Your Data Regularly: Don’t rely solely on the Micro SD card for data storage. Regularly backup your important files to other storage devices or cloud services to avoid data loss in case of card failure.
