Method 2. Erase SD Card Using DiskPart Command

The DiskPart command forms part of the Command Prompt and should be one of the primarily used native methods to erase the SD card securely. If you find the Disk Management utility and other utilities are not working on your Windows device for any reason, it may be worthwhile to consider using the DiskPart command. 

However, since the method involves using the command prompt and entering the commands to get things done, you need to be careful when using the technique. A wrong command or wrong step can create issues, and you may end up erasing a wrong disk or drive. 

Having warned you through that information, here we go with the best steps to assist you in how to erase SD cards using the DiskPart command securely – 

  • Launch Command Prompt on your device. By typing CMD in your Windows Search and picking the appropriate search result, you can do so. 
  • Type in the command diskpart.
  • When Diskpart opens up, type in the command list disk. 
  • Select your disk by typing select disk # where # is the disk number specified by the results of the list disk command above. 
  • Now type in the command clean all

Press ENTER and wait till the disk is erased in its entirety. It is at this stage that you need to be careful. First, ensure that you have selected the correct disk and entered the command to erase its data. Otherwise, you may erase the data on the wrong drive that you did not want to. 

You can either use the clean or clean all command. The clean command deletes the reference to the data, as in the case of the Delete command. The data is not erased securely and can be retrieved through other data recovery tools. Clean All command securely erases all the data beyond recovery. The data is overwritten with random binary numbers, making the data recovery difficult or even impossible.
