How to format right protected sd card​？

Formatting a write-protected SD card can be a tricky task, especially when the card is locked and not allowing you to make any changes.

1. Write Protection on SD Cards

Write protection on an SD card is a security feature designed to prevent accidental data loss. It can also be used to protect important files from being overwritten or deleted. SD cards typically have a physical switch on the side that can toggle between “locked” (write-protected) and “unlocked” (writable) states. However, there are cases where write protection occurs due to software settings, errors, or corruption, making it challenging to format the card.

2. Common Causes of Write Protection

Several factors could cause an SD card to become write-protected:

Physical Write Protection Switch: Most SD cards have a small switch on the side that enables write protection. If the switch is in the “lock” position, the card will not allow any data to be written or deleted.

Corrupted Filesystem: A damaged or corrupted file system on the SD card can trigger write protection, making it impossible to write or delete data.

Malware or Viruses: Malicious software can interfere with your SD card’s functionality and cause write protection to activate.

Operating System Settings: Sometimes, an operating system might impose write protection, either intentionally or as a result of an error.

Bad Sector or Physical Damage: Physical damage or bad sectors on the SD card can also trigger write protection as a protective measure.

3. Checking the Physical Write Protection Switch

Before diving into software-based solutions, the first step is to check whether the SD card has a physical write protection switch. This switch is usually located on the left side of the SD card.

Locate the switch: Look for a small slider on the SD card. If it is pushed down toward the “lock” position, the card is write-protected.

Move the switch: Slide the switch toward the “unlocked” position. This should disable the write protection.

Once the switch is in the unlocked position, try to format the SD card again. If this method works, you can proceed with formatting it using your device. If the write protection persists, proceed to the next steps.

4. Formatting Write-Protected SD Card on Windows

If the physical switch is in the correct position but you’re still unable to format the SD card, you can attempt to remove the write protection using Windows settings or commands.

A. Using Diskpart Command

Diskpart is a powerful built-in tool in Windows that can help you manage disks, partitions, and storage devices. Here’s how you can use it to remove write protection:

Open Command Prompt: Press Win + R, type cmd, and hit Enter to open the Command Prompt.

Run Diskpart: In the Command Prompt window, type diskpart and press Enter. This opens the Diskpart utility.

List All Disks: Type list disk and press Enter. This will display all the disks connected to your computer.

Select the SD Card: Find the number corresponding to your SD card (it will usually be listed as “removable”). Type select disk X, replacing “X” with the number of your SD card, and press Enter.

Remove Write Protection: Type the following command to remove write protection:

arduino

复制编辑

attributes disk clear readonly

Press Enter. This command should disable write protection on your SD card.

Exit Diskpart: Type exit and press Enter to close Diskpart.

After removing write protection, you can attempt to format the SD card using File Explorer or Disk Management.

B. Using Disk Management

Open Disk Management: Press Win + X and select Disk Management from the menu.

Locate the SD Card: In the Disk Management window, find your SD card in the list of drives.

Format the SD Card: Right-click on the SD card and select Format. Follow the on-screen instructions to choose the file system (usually FAT32 or exFAT for SD cards).

Confirm and Format: If the SD card is no longer write-protected, you should be able to format it successfully.

If this method fails, you may want to try other methods outlined below.

5. Using the Windows Registry Editor

If you are still unable to remove write protection using Diskpart, you can try modifying the Windows Registry. Here’s how:

Open Registry Editor: Press Win + R, type regedit, and press Enter.

Navigate to the Write Protection Key: Use the left panel to navigate to the following path:

sql

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

If you don’t see the StorageDevicePolicies key, you may need to create it.

Check for Write Protection Setting: Look for a value named WriteProtect in the right panel. If it’s set to 1. it means write protection is enabled.

Change the Value: Right-click on WriteProtect and select Modify. Change the value to 0 and click OK.

Exit and Reboot: Close the Registry Editor and restart your computer.

After rebooting, attempt to format the SD card again.

6. Formatting Write-Protected SD Card on macOS

If you are using a Mac, the process for formatting a write-protected SD card can be different. Here’s how to do it:

A. Check for Physical Write Protection

Before proceeding with any software-based solutions, check if your SD card has a physical write protection switch and make sure it is in the unlocked position.

B. Format Using Disk Utility

Open Disk Utility: Go to Applications > Utilities and open Disk Utility.

Select the SD Card: In the left-hand panel, select your SD card.

Erase the SD Card: Click the Erase button at the top of the window.

Choose the Format: Select the file format you want (usually exFAT for SD cards).

Erase: Click Erase to begin the formatting process.

If the SD card is still write-protected, proceed to the next steps.

C. Use Terminal Commands

If the Disk Utility method fails, you can try using Terminal commands to remove the write protection:

Open Terminal: Go to Applications > Utilities and open Terminal.

List All Disks: Type the following command to list all connected drives:

nginx

diskutil list

Identify the SD Card: Find your SD card in the list, which will usually be listed as /dev/diskX, where X is the number of the SD card.

Unmount the SD Card: Type the following command to unmount the SD card (replace X with the disk number):

bash

diskutil unmountDisk /dev/diskX

Remove Write Protection: Use the following command to remove write protection (replace X with the disk number):

bash

sudo diskutil disableOwnership /dev/diskX

Format the SD Card: Finally, use the following command to format the SD card:

bash

sudo diskutil eraseDisk exFAT SDCard /dev/diskX

This should format the SD card and remove the write protection.

7. Using Third-Party Software

If the above methods don’t work, third-party software tools can help you unlock and format a write-protected SD card. Some popular tools include:

SD Formatter: A tool specifically designed for formatting SD cards. It is available for both Windows and macOS.

EaseUS Partition Master: A comprehensive disk management tool that allows you to manage partitions, including formatting and removing write protection.

MiniTool Partition Wizard: Another popular partition manager that can help with formatting and managing write-protected SD cards.
