How to Fix a Corrupted SD Card in Windows 7
Method 1: Use CHKDSK to Repair the SD Card
One of the easiest ways to fix a corrupted SD card in Windows 7 is by using the built-in CHKDSK utility. Here’s how to do it:
Insert your SD card into your computer’s card reader.
Open the Start menu, type “cmd” in the search bar, and press Enter.
Right-click on “Command Prompt” and select “Run as administrator”.
In the command prompt, type the following command, replacing “X” with the drive letter of your SD card: chkdsk X: /f /r /x
Press Enter and wait for the process to complete.
This command will scan your SD card for errors, fix any issues it finds, and recover any readable data.
Method 2: Use Windows Explorer to Format the SD Card
If the CHKDSK method doesn’t work, you can try formatting your SD card using Windows Explorer. Keep in mind that formatting will erase all data on the card, so make sure to back up any important files first.
Insert your SD card into your computer’s card reader.
Open “My Computer” or “This PC”.
Right-click on the corrupted SD card and select “Format”.
In the Format window, select the file system you want to use (e.g., FAT32, exFAT, or NTFS).
Click “Start” to begin the format process.
Method 3: Use EaseUS Partition Master to Repair the SD Card
If the built-in tools don’t work, you can try using a third-party partition management software like EaseUS Partition Master. This tool offers advanced features for repairing corrupted SD cards, including surface testing for logical and physical errors, bad sector checking, and secure wiping.
Download and install EaseUS Partition Master on your computer.
Launch the software and locate your corrupted SD card in the main window.

Follow the on-screen instructions to perform the surface test and repair any errors found.
Method 4: Use a Data Recovery Tool to Recover Data
If your SD card is severely corrupted and you can’t access your data, you can try using a data recovery tool like EaseUS Data Recovery Wizard. This software can scan your SD card for recoverable files and help you restore them to your computer.
Download and install EaseUS Data Recovery Wizard on your computer.
Launch the software and select your corrupted SD card from the list of available drives.
Click “Scan” to begin searching for recoverable files.
Once the scan is complete, preview the files and select the ones you want to recover.
Click “Recover” to save the files to your computer.
Method 5: Update the SD Card Driver
If the above methods don’t work, the issue may be related to an outdated or faulty SD card driver. You can try updating the driver to see if it resolves the problem.
Open the Device Manager by pressing the Windows key R, typing “devmgmt.msc”, and pressing Enter.
Expand the “Disk drives” category and locate your SD card.
Right-click on the SD card and select “Update driver”.
