Why would you wipe SD card? Reasons can be: reading on SD card is getting slower when enough free space available; SD card performances poor after times of use; simply give it others wondering no trace to your SD card, delete file is not a secure way of keeping data safe, and there may be more. We'll guide on how to wipe SD card in Windows 10 using diskpart command line and other system utility.

Wipe SD card using diskpart, right-click on start menu, and select command prompt (Admin), in the cmd window, type the following commands:

  1. diskpart >> list disk >> select disk ### >> clean
  2. exit

You can also insert the SD card to a card reader so Windows will treat this SD card reader as a USB flash drive, then right-click on the drive in Windows Explorer and select format from the menu, or just use Disk Management and right click the largest disk number, right-click to choose format. However, format only remove the original file system and create a new one, it doesn't wipe data.
