Quick Overview

Three quick ways to fix write protection errors on SD cards in Windows are: toggle the card’s lock physical switch, check the card’s properties and free up space, or reset its attributes via Command Prompt.

Almost all full-size SD cards include a slider that acts as a write-locking mechanism; microSD cards can be placed into an adapter with such a feature. (Yes, the lock switch.)

To check if your device has been accidentally set to read-only mode, open This PC, right-click on the card’s entry, and then choose Properties.

If neither of these methods worked out well for you, try clearing your card’s write-protected status using the Diskpart utility from Command Prompt (Admin) or PowerShell (Admin).

Different Ways to Fix Write Protection Errors on SD Cards in Windows

Here are three ways to fix write protection errors on SD cards:

Different Ways to Fix Write Protection Errors on SD Cards in Windows

Method 1: Unlock the Switch on the SD Card Itself

The first thing you should check is if there is a switch on the side of your SD card that is preventing it from being written onto. This could be due to accidental contact with the switch while transferring data or simply because of wear and tear on the device over time. To unlock it, move the switch back into its original position and try writing data again.

Method 2: Tweak Your Registry Settings

If the switch on your device isn’t locked, then another potential solution could be to tweak your registry settings. To do this, you will need to open up your registry editor and navigate to:


Once here, change the value for WriteProtect from 1 (enabled) to 0 (disabled). You can now try writing data onto your SD card again.

Method 3: Format SD card

If neither of these methods works, then formatting your memory card could be a way around this issue. Before doing so, ensure you have backed up any important files, as formatting will wipe everything on the Drive!

To format your device, go into File Explorer, right-click on the Drive, and select ‘Format’ from the menu that appears. Then follow the instructions that appear until you eventually see ‘Format Complete.’

Let’s look at recovering the data.

How to Recover Data From a Write-Protected SD Card 

How to Recover Data From a Write-Protected SD Card 
  • Checking if your device has been set to read-only mode can be a helpful way to troubleshoot write protection errors on SD cards in Windows. This mode could have been accidentally enabled while transferring data, resulting in the inability to access, edit, or delete files on the card.
  • To check if your device has been set to read-only mode, you can use Diskpart. To do this, open the command prompt and type in “diskpart,” followed by the drive letter of your SD card. You will then see if the device is set as “read-only.”
  • If your device has been set to read-only mode, you can use a tool like EaseUS Data Recovery Wizard to recover the lost data. This software is designed to help users recover files from write-protected SD cards.

Download and install the software onto your computer and connect your SD card. It will automatically detect the device and start scanning it, recovering any lost files that were previously inaccessible. Once the process is complete, you can access these files as if they had never been deleted in the first place!

Ok great. What about the error messages?

 Fix for Error Messages Related to Write Protection

Create a new partition and format it with NTFS/FAT32 file system.

Follow these steps: 

  • Launch MiniTool Partition Wizard.
  • Right-click on the partition on your SD card which you want to format, then select the “Format” option from the context menu.
  • Input your desired partition label, then select the file system of your choice. This application can format your SD card into NTFS, FAT32, EXT2, or EXT3.
  • Click OK to begin the formatting process, and be aware that all data on the selected partition will be erased.
  • Review all changes and click “Execute Operation” to finalize formatting.

I recommend MiniTool as its customer support is better than Recuva or EaseUS.

Advantages and Disadvantages of Read/Write Protection on SD Cards 

Pros: prevents accidental deletion or overwriting, useful for data integrity and stability, inexpensive way of protecting data from theft and unauthorized access  

Cons: it can be time-consuming if you need to change the settings regularly, may prove inconvenient when transferring files between different devices, and does not offer complete security against attackers.

The only task remaining is to know how to secure your data.

The Best Methods for Securing Your Data On An SD Card 

Here are the best ways to secure your data:

A. Set up password protection on your card – use only complicated passwords with special characters and numbers; avoid choosing simple ones that are easy to guess

B. Enable encryption – both hardware-level and software-level encryption can be used; choose one that best fits your needs

C. Use two-factor authentication – an extra layer of security that requires two independent sources of identification before granting access

D . Install anti-malware software – this helps prevent malicious software from accessing your card and protects your computer when connecting the card.
