SD Clean/Windows

This is an add-on section for completely recreating an SD card's filesystem using diskpart. This should only be done if formatting does not fix your issue or is not possible for some reason.

This page is for Windows users only. If you are not on Windows, see the Mac and/or Linux pages instead.

Instructions

Before beginning these steps, copy all of your SD card's contents to a folder on your computer.

1. Launch diskpart by searching for diskpart in the Windows search bar.
2. Once diskpart is active in the new Command Prompt window, type list disk.
3. Find your SD card in the list of disks (hint: look for the size of your card), then type select disk #, where # is the disk number of your SD card.

   Never select disk 0! This will always be your main windows drive.

4. Type list disk again. You should now see a * next to your SD card.
5. Once you are absolutely sure that you have selected the right disk, type clean, then type convert mbr.
6. Close the diskpart window.
7. Format the SD card.
8. Once the format is complete, copy your data back onto the SD card.
