How Do I Recover Files from My SD Card That Won't Read?

SD cards are widely used for storing important data, including photos, videos, and documents. However, encountering an unreadable SD card can be frustrating, especially when it contains valuable files. If your SD card isn't being recognized by your device, don’t worry—there are several methods you can try to recover your data. In this guide, we will walk you through the steps to fix an unreadable SD card and restore your lost files.

Common Reasons Why an SD Card Won’t Read

Before attempting recovery, it’s essential to understand why your SD card isn’t being recognized. Some common causes include:

  • Physical damage – Broken or bent SD cards may be unreadable.
  • File system corruption – If the file system is corrupted, your device may not detect the SD card properly.
  • Driver issues – Outdated or missing drivers can prevent the SD card from functioning.
  • Virus infection – Malware or viruses can corrupt your SD card’s data.
  • Improper ejection – Removing the SD card without safely ejecting it can cause data corruption.

Steps to Recover Files from an Unreadable SD Card

1. Check the SD Card on Another Device

Before proceeding with advanced solutions, insert the SD card into a different computer, camera, or mobile device to see if it is detected. Sometimes, the issue is with the device rather than the card itself.

2. Use a Different Card Reader

If your SD card isn’t detected, try using a different card reader or USB adapter. Faulty hardware may be the reason your card is unreadable.

3. Assign a New Drive Letter

If your SD card is visible in Disk Management but does not appear in File Explorer, assigning a new drive letter may help:

  1. Press Win + X and select Disk Management.
  2. Locate your SD card.
  3. Right-click and choose Change Drive Letter and Paths.
  4. Click Add or Change, then select a new letter.
  5. Click OK and check if the card is accessible.

4. Run CHKDSK to Repair Corrupt SD Card

Windows has a built-in tool called CHKDSK that can fix file system errors. To use it:

  1. Connect your SD card to a PC.
  2. Open Command Prompt (press Win + R, type cmd, and press Enter).
  3. Type the following command and press Enter: 
    chkdsk X: /f /r /x
    (Replace "X" with your SD card’s drive letter.)
  4. Let Windows scan and repair the card.
  5. Once completed, check if you can access your files.

5. Use File Recovery Software

If your SD card remains unreadable, try using third-party recovery software like:

  • Recuva
  • EaseUS Data Recovery Wizard
  • Disk Drill

These tools can scan your SD card and attempt to recover lost or corrupted files.

6. Reinstall SD Card Drivers

If your SD card isn’t recognized, reinstalling its drivers may help:

  1. Press Win + X and select Device Manager.
  2. Expand Disk Drives and locate your SD card.
  3. Right-click and select Uninstall device.
  4. Remove and reconnect your SD card.
  5. Windows will reinstall the drivers automatically.

7. Format the SD Card (Last Resort)

If all else fails and you need to recover your SD card’s functionality, formatting might be necessary. Be aware that formatting will erase all data on the card.

  1. Right-click on the SD card in File Explorer and select Format.
  2. Choose the file system (exFAT or FAT32).
  3. Click Start and wait for the process to complete.

If you need to recover files before formatting, make sure to use a data recovery tool first.

Preventing SD Card Issues in the Future

To avoid encountering unreadable SD cards in the future, follow these best practices:

  • Safely eject the SD card before removing it.
  • Use high-quality SD cards from reputable brands.
  • Keep backups of essential files.
  • Avoid filling the SD card to capacity to prevent corruption.
  • Run periodic scans to detect malware or errors.

Conclusion

An unreadable SD card doesn’t necessarily mean your files are lost forever. By trying different troubleshooting methods—such as using file recovery tools, running CHKDSK, or reinstalling drivers—you may be able to retrieve your data successfully. If you need to access your files urgently, software recovery programs can be an effective solution. Lastly, always ensure you handle and store your SD card properly to prevent future issues.

If your SD card is still unreadable, you can try accessing it using the command file ///sdcard/ on some devices to see if any files are retrievable. However, this method may not work in all cases, so using recovery software remains the best option.
