Method 2: Try a Different Card Reader or Device
Card readers fail sometimes. The problem might not be your SD card. It could be the reader itself. Ports get damaged. Connections become loose. Dust accumulates in USB ports. This blocks proper contact. Old card readers lack support for newer cards.
Testing with different hardware is smart. You eliminate the reader as the problem. This simple step saves time. It helps you understand how to recover files from unreadable SD card without complex tools. Sometimes the issue is just a bad connection. Trying another device costs nothing. It takes only minutes to test. This method works surprisingly often.
How to Try a Different Card Reader or Device:
- Remove your SD card from the current reader. Try another card reader if you have one. Or insert the card directly into your laptop's built-in slot.

- Check if your computer now recognizes the card. Try different devices, like another computer or camera. If the card works elsewhere, your original reader or port has issues. If it still doesn't work, move to the next method.
Method 3: Use CHKDSK Command (Windows)
CHKDSK is a Windows tool. It fixes file system errors. The command checks disk integrity. It repairs bad sectors automatically. This utility has existed for decades. Microsoft built it into every Windows version. It's trusted by professionals worldwide. The tool works at the system level.
This built-in utility is powerful. It solves many SD card problems. No extra software needed. Learning how to recover data from unreadable SD card often starts here for Windows users. CHKDSK scans the entire card structure. It identifies problematic areas. Then it attempts repairs automatically. The process is thorough and reliable.
How to Use CHKDSK Command:
- Connect your SD card to PC. Press Windows key + R to open the Run dialog. Type "cmd" and press Enter to open Command Prompt. Note your SD card's drive letter from File Explorer.

- In Command Prompt, type "chkdsk X: /f /r/x" where X is your SD card drive letter. Press Enter. Wait for the process to finish. It might take several minutes. Restart your computer and check if the card is now readable.
Method 4: Assign a New Drive Letter
Windows assigns letters to drives. Sometimes conflicts happen. Your SD card gets no letter. Or it shares a letter with another drive. Network drives can cause conflicts. External drives use up available letters. The system gets confused.
Without a proper drive letter, cards become invisible. The system can't access them. This method fixes that problem. It's a simple way to recover unreadable SD card access. Drive letter assignment takes seconds. You just need administrative access. The fix is permanent once applied. Your card will work normally after this.
How to Assign a New Drive Letter:
- Right-click on "This PC" or "My Computer" and select "Manage." Click on "Disk Management" in the left panel. Look for your SD card in the list of drives.

- Right-click on your SD card partition. Select "Change Drive Letter and Paths." Click "Change" or "Add" if no letter exists. Choose a new letter from the dropdown. Click OK and close Disk Management. Check if your card now appears in File Explorer.

Method 5: Update or Reinstall Drivers
Drivers help hardware communicate with Windows. Outdated drivers cause problems. Corrupted drivers stop cards from working. Your system can't read the card properly. Windows updates sometimes break drivers. Malware can corrupt driver files. Old drivers lack support for new card formats.
Updating drivers is easy. Windows can do it automatically. This often solves recognition issues. Many people learn how to recover data from an unreadable SD card through this simple fix. Fresh drivers restore proper communication. They enable full card functionality. The process requires no technical expertise. Windows handles everything for you.
How to Update or Reinstall Drivers:
- Press Windows key + X and select "Device Manager." Expand "Disk drives" section. Find your SD card reader in the list. Right-click on it.

- Select "Update driver" from the menu. Choose "Search automatically for updated driver software." Windows will search and install updates. If that doesn't work, right-click again and select "Uninstall device." Restart your computer. Windows will reinstall the driver automatically.
Method 6: Format the SD Card (Last Resort)
Formatting erases everything on the card. It creates a fresh file system. This is your last option. Try all other methods first. Formatting should make you nervous. That's good. It means you'll be careful. The process is irreversible once completed. Your old data structure disappears completely.
Format only if nothing else works. You lose current data. But you can use the card again. If you've backed up files or used Recoverit first, formatting makes sense. This completes your knowledge of how to recover files from unreadable SD card scenarios. A formatted card is like new. It has no errors or corruption.
How to format SD card:
- Backup any accessible data first. Use Recoverit to scan and save files before formatting. Open "This PC" in Windows. Right-click on your SD card drive.

- Select "Format" from the menu. Choose FAT32 for cards under 32GB or exFAT for larger cards. Uncheck "Quick Format" for thorough formatting. Click Start and wait. Your card will be clean and ready to use again.

FAQs
-
Q1: Can I recover data from a physically damaged SD card?
Physical damage makes recovery harder but not impossible. Small cracks or bent cards might still work with careful handling. Try connecting the card to see if it's recognized at all. Professional data recovery services use special equipment for badly damaged cards. They can often retrieve data even from broken cards. However, if the chip inside is destroyed, recovery becomes nearly impossible. -
Q2: Why does my SD card suddenly become unreadable?
Several reasons cause SD cards to become unreadable suddenly. Improper ejection damages the file system. Power failures during file transfers corrupt data. Virus infections can make cards inaccessible. Wear and tear from years of use degrades the memory. Bad sectors develop over time. Using the card across multiple devices increases corruption risk. File system incompatibility between devices causes problems too. Sometimes it's just the card reader failing, not the card itself. -
Q3: Is free data recovery software as good as paid versions?
Free software has limitations compared to paid versions. They often restrict recovery size to a few hundred megabytes. Advanced features like deep scan are locked. Technical support isn't available with free tools. However, free versions work fine for small recovery tasks. They help you test if files are recoverable. Paid software like Recoverit offers unlimited recovery. They provide better algorithms.
