How To Repair Corrupted Memory Card/USB Pen Drive

Today in this digital world, everything is based on data transfer that is possible through portable memory storage devices: the memory card, pen drives, and Hard drives.

However, sometimes viruses and improper ejection of these drives lead to corruption. And in that case, Windows can’t properly format your portable memory drive.

Best Ways to Repair Corrupted Memory Card/USB Pen Drive

So to resolve this issue, we are here with the best methods to repair corrupted memory card or USB drive. With these methods, you can easily repair your drive and use it.

1. Connect The USB Device To Another Computer

We mainly face SD card or Pendrive issues due to incompatibility or related issues. So, before you conclude that your USB or SD card is damaged and useless, try to connect it to other devices.

If the USB device works fine on other devices, you must work on your computer rather than a USB or SD card. So, this is the very first step that you should take to check or repair your SD card or USB flash drive.

2. Using Troubleshooter

You can use the Command Prompt to run the hidden hardware and devices troubleshooter in Windows. Running the hardware and devices troubleshooter will find and fix existing problems with all your connected hardware, including the USB flash drive.

So, if the USB flash drive is corrupted due to some unknown issue, running the hardware and devices troubleshooter may help. Here’s how you can run it.

1. Click on Windows Search and type in CMD. Right-click on the CMD and select Run as administrator.

2. When the Command Prompt opens, execute the command:

msdt.exe -id DeviceDiagnostic

3. This will open the Hardware and Device Troubleshooter. Click on the Next button.

4. Now, follow the on-screen instructions to complete the troubleshooting part.

That’s it! The Hardware and Devices troubleshooter of Windows will automatically find and fix existing hardware or device problems.

3. Updating USB Driver

If Windows fails to read your USB drive, outdated drivers might be the reason. Sometimes updating the device driver could fix any existing problem. Here’s how you can update the device drivers

1. Open the RUN dialog box and type in devmgmt.msc. It will open up the Device Manager.

2. Now, you need to expand the Universal Serial Bus Controllers. Here you will see the corrupted or unrecognized USB devices as ‘Unknown Devices’

3. If there are no unknown devices, right-click on the USB Mass Storage Device, and select Update driver.

If the connected USB device needs an update, the Driver update wizard will let you know. Simply update it to fix existing issues of the Memory Card/Pendrive.

4. Changing the Drive Letter

Sometimes your computer cannot assign the drive letter to your storage media. This might be the reason the files on it can’t be accessed. Therefore, make sure your drive has a letter, or you need to assign the drive letter to your device. Here’s how you can fix your pen drive or memory card by assigning a correct drive letter.

1. First, click on the Windows search and type Disk Management. Next, open the Disk Management utility from the list of matching results.

That’s it! This will change the drive letter of your Pendrive.

5. Scan the Corrupted Memory Card with Antivirus Program

 

Malware and viruses are prominent reasons for corrupted data on the PenDrive. While the latest version of Windows has a robust security tool called Windows Security, certain malware can still slip off onto your USB drive.

So, it’s best to use a reliable antivirus solution to scan for malware and viruses. You can use antiviruses like Malwarebytes, AVG, or Kaspersky to find and remove viruses and malware from your USB flash drive.

6. Reinstalling the Device

In this method, we will use EaseUS Partition Master to format the SD card completely. However, it’s worth noting that this method will delete all files stored on the SD card.
