How to Tell If an SD Card Is Corrupted: Common Signs

"Corruption" is a broad term, and it's hard to tell precisely what refers to a corrupted SD card. Usually, when a Windows PC, Android phone, or digital camera can not read or recognize a memory card, it sends strange error messages that prevent you from accessing data. From this, we can determine that the SD card has been corrupted. For example:

From Reddit:
My camera won't read the SD card and recommends to format it, my fathers PC says the same thing and my MacBook just keep giving me this message "The disk you attached was not readable by this computer".
I tried to go to Disk Utility and use the First Aid button but i didn't work. What can I do? Is there any free or not so expensive program or app for this? I'm kind of desperate because it was a 12 hours work...
 

Based on the requests we have received and our ten years of experience in the SD disk recovery industry, generally speaking, when the SD card shows the following signs, it is a sign of damage:

How to repair corrupted SD memory card? We will provide you with five solutions to help you fully fix and retrieve a corrupted SD card in Windows 10/8/7:

Fix 4. Change the SD Card Drive Letter

The drive letter conflict can cause Windows not to recognize the removable disk that is externally connected to it, making the SD card look corrupted. So, assigning a new drive letter unique to the SD card can help Windows re-recognize it.

Step 1. Insert the SD card into your computer and open Disk Management.

Step 2. Right-click on the SD card and select "Change drive letter and path...".

Step 3. Set a new drive letter for the card.

When the process finishes, check if you can access your card.

Fix 5. Corrupted SD Card Recovery Using CMD

When the file system of the SD card gets corrupted, be it NTFS, FAT32, or exFAT, you'll most likely receive the error messages that say, "The file system is RAW", "the disk is not formatted", "the drive is not accessible", and so on. This makes the memory card unable to work usually. Here, we'll try to fix the corrupted SD card using CMD.

Step 1. Insert the corrupted SD card into your PC using a card reader.

Step 2. Press Win + X and select "Command Prompt".

Step 3. Right-click "Command Prompt" and then select "Run as administrator".

Step 4. Type the command: chkdsk [sd card drive letter]: /f /r /x and press Enter. Replace the SD card drive letter with the actual letter of your SD card drive.

Caution: Note that this command will cause a permanent file loss error. So before you execute the operation, ensure you recover data from your corrupted SD card with the reliable EaseUS Data Recovery Wizard.

Chkdsk will check and fix any possible errors on the corrupted SD card and make it readable again.

The worst thing that can happen is you cannot find the SD card in Windows Disk Management. How do you troubleshoot an SD card that is corrupted to this degree? Windows Device Manager is where you need to check the driver update information for the SD card. An outdated or corrupted driver will also cause your SD card to malfunction.

Step 1. Connect the corrupted SD card to the PC, right-click on This PC/My Computer, and select "Manage".
