4 Ways To Fix Your Corrupted Memory Card



1. Try Using Your Memory Card On Other Devices

When you encounter some of the above-listed signs in your memory card, you may not have to conclude hastily that the card is corrupted. You may simply try other methods to ascertain the status of your SD card. That is exactly what to do. 



Simply insert your card into a variety of different devices that is SD card-compatible such as smartphones, laptops, tablets, and so on. It may turn out that the card is not only compatible with your device, or that it has issues related to the driver of your computer.



2. Test For “chkdsk” Command Errors 

chkdsk Command Errors



If you still get the initial symptoms after comparing your memory card with other devices, try checking for errors with the “chkdsk” command. To achieve the desired results with this method carefully follow the steps below:




  • Select the “Start” button on your Windows Taskbar and choose “Computer”. Then go to “Devices with Removable Storage” and from the drop-down box, find your card under it, take note of the assigned Drive letter of your card. 


  • Again, click on the Start menu and type in the letters “cmd “- which is the command in the search box. Right-click on the cmd button. When it comes up, choose “Run as Administrator” as your choice.


  • Fix the corrupted memory card by typing the “chkdsk” letters in the command window that opens afterward. What follows, at this point, is your card drive letter, colon (:) and “/f”. Your card drive letter is the letter displayed on your computer when performing step (iii) above. This is what you get, for example: “chkdskc:/f” (excluding the quotation marks).


  • To start the “chkdsk” checking process for potential errors, click the “Enter” key on your keyboard. Next, begin replacing the corrupted SD card and carefully follow the prompts that will inevitably pop up. Wait until the CHKDSK software finishes checking your memory card for systemic error. 


  • Press the letter ‘Y’ on your keyboard to allow the software to continue checking your SD card until you can identify the files and directories you saved on your memory card. Once the CHKDSK test process is done, you will be prompted to transfer missing chains to the archives.


  • Click on the ‘Yes’ option. In a few moments, “chkdsk” will display all your missing data files that have been restored on your computer. Go back and review your card drive letter to confirm that your memory card has been recovered and that your files have been retrieved. But, if you discover that the files have not been retrieved or that you still find it difficult to assess your files. Then allocate your SD card with a new drive letter.



Using your computer, you can allocate a new drive letter to your card by following these simple steps:


locating disk management on computer



  • Right-click ‘Start’ button
  • Click on the “Disk Management” to open the screen. 
  • Right-click on the volume of the drive letter you wish to change 
  • Choose from the available list of drive letters given and select “OK” At this point, you will be asked to choose “Yes” “if you really want to try to do this.” 
  • Once finished, you can remove the “disk management” console by clicking on it.



3. Format Your SD Card

You can decide to format your SD memory card and erase all data in it. And you can start using these steps on your computer again. 



  • Attach the affected SD card to your device using a card reader or some other adapter
  • Click the “Start” button. Then click on the computer to take you to “my computer”.
  • All of your hard drives will appear in the “My Computer” tab. If the files do not, select on the computer from the left menu.
  • Your memory card should be seen listed here under “Devices with Removable Storage.” To show the context menu of your SD card, right-click your card. Select “Format” to view from a range of formatting choices. Tick the box next to “Fast Format” for faster operation. Finally, select the “Start” button to start the operation.

  • Using cotton wool or cotton swab, apply a large amount of precision cleaning agent to moisten it. 
  • Use the moist cotton swab to clean the surface of your memory card. 
  • With a sharp tool like a knife, gently scrape the surface of the panel (use it like you’re attempting to remove excess dirt). Once done, clean the surface again with the cleaning agent and leave it to dry. Insert the memory card back to your device or computer to be certain it’s working.

EaseUS Data Recovery Wizard





Finding the right memory card recovery application software out of the many can be quite tasking. Top of the data recovery software list is the EaseUS Data Recovery Wizard developed in 2004. However, based on consumer experience, it has remained the best with proven data recovery outcomes with more than 100 real-life data loss scenarios of all kinds. It is lightweight, easy to install, and use. 



The EaseUS data recovery wizard is most recommended for people with little to no technical knowledge of computing in order to prevent complicated issues using the CHKDSK recovery tool.

It also supports almost all file systems, including NTFS5, exFAT, and lots more.

Another ideal data recovery software is the Disk Drill Recovery software created by CleverFiles. Disk Drill is a data recovery software for professionals.
