Part 1. How to Unlock SD Card in 4 Tested Methods

If you encounter the issue where your SD card is locked or write-protected, we can assist you in resolving it. Here are four effective methods: 1. Manually unlock your SD card 2. Remove write protection in Windows & Mac 3. Unlock SD card with a password Follow these steps to address the problem: 1. **Manually Unlock SD Card**: Check the physical lock switch on the side of the SD card. If it's in the locked position, slide it to the unlocked position. This switch only controls read-only access and doesn't affect write protection in software. 2. **Remove Write Protection in Windows**: - Connect the SD card to your Windows computer. - Open File Explorer, right-click on the SD card, and select "Format." - In the Format window, ensure the "Quick Format" option is checked, and then click "Start." - A warning will appear; click "OK" to format the card, which should remove write protection. 3. **Remove Write Protection in Mac**: - Insert the SD card into your Mac. - Open Disk Utility (found in Applications > Utilities). - Select the SD card from the list on the left. - Click the "Erase" button, choose a format like "MS-DOS (FAT)" or "ExFAT," and then click "Erase." - The process will remove write protection and format the card. 4. **Unlock SD Card with a Password**: - Use a third-party tool, such as CardRecovery or tools, which often have features for unlocking password-protected SD cards. - Follow the software's instructions to unlock the card. Note that this method may not work if the card has been genuinely write-protected and not just password-protected. Remember that formatting or unlocking may lead to data loss, so always back up your important files before proceeding.

Method 1: Manually Unlock the SD Card

This method will help you remove physical write protection. On the left side of the SD card, there's a Lock switch. Ensure that the Lock switch is slid up (in the unlock position). If the card is locked, you won't be able to modify or delete any content on the memory card.

If the lock switch feels loose and moves effortlessly, it's possible that the switch is sliding into the locked position as the card is inserted into your host device. In this scenario, the card would need to be replaced.

This method focuses on removing write protection using the Command Prompt (CMD) to unlock your SD card. If you're not familiar with CMD, you can opt for an alternative. Continue reading and follow the steps below:

Step 1. Ensure that you're logged in with an administrator account. Connect the SD card to your computer.

Step 2. Click the Windows logo in the bottom-left corner of the screen. Search for "Command Prompt" and then click "Run as Administrator."

Step 3. Enter each of these commands individually and press "Enter" after each one:

Here's how to unlock an SD card on a Mac: 1. Connect the SD card to your Mac using a card reader or a device with an SD slot. 2. Open "Finder" by clicking on its icon in the Dock or using Spotlight (press Command + Space). 3. In the Finder window, navigate to the "Devices" section on the left sidebar. You should see the name of your SD card listed there. 4. Right-click on the SD card's name and select "Get Info" from the context menu. Alternatively, you can press Command + I while the SD card is selected. 5. A small window will appear with details about the SD card. Look for the "Sharing & Permissions" section at the bottom of the window. 6. Click the lock icon in the lower right corner to make changes. You'll be prompted to enter your Mac's administrator password. 7. After entering the password, you'll be able to modify the permissions. Find the user or group listed under "Owner & Group" or "Everyone," then click the lock icon next to the read-only permission setting. 8. Change the read-only setting from "Read Only" to "Read & Write." Make sure the "Apply to enclosed items" checkbox is selected if you want to change permissions for all files and folders within the SD card as well. 9. Click "OK" to save the changes and close the "Get Info" window. 10. The SD card should now be unlocked, and you should be able to modify its contents. Remember to eject the SD card safely before physically disconnecting it to avoid data loss or corruption.

Step 1. Connect your SD card to your Mac device.

Step 2. Check and remove the write protection on the SD card.

Right-click on a file on the SD card and select "Get Info." In the resulting window, under the "Sharing & Permissions" section, you'll see "Read Only" listed under Privileges. To modify this, click on the lock icon in the bottom right corner and enter your administrator password to unlock the settings. Once unlocked, click on "Read Only" and change it to "Read & Write."

Method 4: Unlock/Decrypt SD Card with Password

If your memory card or SD card is secured with a password, this approach would be applicable. If you utilized a third-party encryption software to encrypt the card, you can conveniently decrypt it using the same tool with the correct password. If you locked the SD card using an Android phone, the only means to access the data on the card would be to decrypt it. For illustrative purposes, we will demonstrate how to decrypt the SD card with a password on a Samsung phone: 1. **Unlock your Samsung phone** and go to the home screen. 2. **Access Settings**: Swipe down from the top of the screen and tap on the gear icon to enter the settings menu. 3. **Locate and open 'Lock screen and security'**: Scroll down through the settings options and find 'Lock screen and security' or 'Security' (depending on your phone's version). 4. **Select 'Other security settings'**: This option might be nested within 'Lock screen and security'. 5. **Tap on 'Encrypt and decrypt storage'**: You might find this under 'Encryption and credentials' or 'Storage and USB'. 6. **Choose 'Decrypt SD card'**: The option might say 'Decrypt external storage' or something similar. 7. **Enter your password**: At this point, you will be prompted to enter the password that was set for the SD card encryption. 8. **Wait for decryption process**: After entering the correct password, the decryption process will begin. This may take some time depending on the size of data on the SD card. 9. **Confirm successful decryption**: Once completed, your SD card should now be decrypted, and you can access its contents. Remember that the steps might vary slightly depending on your Samsung phone model and Android version. If you face any issues, consult your device's user manual or contact Samsung support for assistance.

Tip
You can't decrypt the SD card on another device. Different devices use different encryption algorithms, so the decryption methods vary. To access all the data saved on the SD card, we recommend that you decrypt it on the original device.

Step 1. Insert the SD card into the source Samsung phone and restart it. Proceed to "Settings" and tap on "Lock screen and security".
