SD Card Suddenly Write Protected, How to Fix

I've been using the SD card on my Wii for a few months, but yesterday when I removed it to add some homebrew apps, my computer said it was write-protected. What should I do to remove this error?

Don't worry; this is a common problem. Memory SD card is locked in "read-only" mode; this is because the card is getting old, damaged, corrupted, or infected by a virus. Sometimes human error can also make an SD card read-only. You can fix this error via CMD commands, but please be careful when you type the following commands:

Step 1: Plug the read-only SD card into Windows.

Step 2: Click the Windows icon, choose Run, and enter cmd in the new window.

Step 3: Enter diskpart and hit enter.

Step 4: Type list disk; then hit enter.

Step 5: Type select disk 1. 1 represents the letter of your SD card.

Step 6: Type attributes disk clear readonly to remove the write protection.

If you don't consider yourself a professional computer user and are unfamiliar with the command line, turning to third-party software can help you remove write protection from hard drives, USB drives, and even SD cards.

EaseUS Partition Master stands out from many write protection removal tools. It allows you to remove the write protection with simple clicks, and you don't need to type any commands during this process.

Step 1. Download and launch EaseUS Partition Master, and click "Write Protection" in the "Toolkit" section.

Step 2. Locate your SD card and choose "Disable."

However, if none of the ways work, Chances are your SD card is encrypted by a virus or malware.

Here are the tools I used to use to remove viruses:

Norton Antivirus, ESET NOD32, Avira, Avast, AVG, McAfee, etc.
