When connecting an SD card to a Windows computer or even a mobile phone, it shows “Memory Card write Protected” or “Microsd card write protected” error and couldn’t format it. At that time there’s no possibility to copy the MicroSD card files to another device. Moreover, sometimes Android shows a corrupted micro sd card, need to format message. In most cases, it happens external volume file system errors.
Almost all of our valuable photos, favorite music are stored on our smart devices’ external memory card. If you are not able to recover them you lost all your valuable memories.
There’re several ways to fix write protected error. In this post, I’m going to use the Windows operating system to solve this issue. You have to log in to your PC using an Administrator account. In this post, I’m using the Windows 10 OS, however you can use any Windows operating system.
First, make sure that you’re not manually trigger SD card write protected state.
Disable Write Protected policy on Windows.
- Open the “Run” command window. In Windows 10, right-click on the “Windows” icon and choose “Run”.
- Type “regedit” without quotes.
- When the Windows registry editor opens, you can see a list of folders. Navigate to the following entry by double click on that visible folder icon. “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control“
- Search if there’s a “Storage Device Policies” registry key. If you can’t find such a key, we have to create a new key. Right-click on the “Control” registry key and navigate to “New>Key”.
- Rename the newly created key as “Storage Device Policies” without quotes.
- Now right click on the right-side panel and choose “New>DWORD Value”.
- Rename it has “write protect” without quotes.
- Double click on that write-protect keys and change its value to “0”.
How To Remove Write Protection On Micro SD Card.

attributes disk clear read
- Next, eject the USB adapter and reconnect.
Check the disk errors.
Next, we have to check if there are any microSD corrupted errors. Open the command prompt as you opened in the above step.
- First, identify the driver letter assigned to your micro SD card. You can view it by opening Windows “File Explorer”. In my situation, you can see that it’s assigned the letter “G”.
- Type the following command line and hit the enter key. If your computer assigned a different drive letter for your memory card, then replace that letter with the following command line “G“.
chkdsk /f /r G:
- Now it starts the error checking and if it found, it will automatically fix. This will take a couple of minutes.
Now connect your MicroSD card to a mobile phone and access the SD card using our recommend non-root or root file manager app and check it’s working.
