When your SD card, pen drive or USB drive becomes inaccessible with the write protection enabled, you'll not be able to use it to store new data or transfer data normally. Basic functions such as installing new data, delete data or move data from one drive to a new one will all being shut down by then. How to fix such a problem? The direct solution is to remove the write protection on SD card or USB drive etc storage devices.
There are several attainable ways for you to remove the write protection and among all, EaseUS Tools M is the most recommended. It's third-party write protection removal software that simplifies the command methods and enables the most efficient and quickest way to unlock a write-protected SD card.

EaseUS Tools M is a practical computer fixing tool that is safe and light-weighted. It's a perfect alternative to the command line.
Use this one-click tool to solve the write-protection issues on your own:
Step 1: DOWNLOAD and install EaseUS Tools M for free.
Step 2: Run EaseUS Tools M on your PC, choose the "Write Protection" mode.
Step 3: Select the device which is now "Write-Protected" and click "Disable" to remove the protection.
Besides the automatic way of downloading write protection removal software to unlock the SD card, you can also try the other three methods to restore the write protected storage device back to normal, all by yourself.
Method 1. Check the Lock Switch on Your SD card/USB Drive
The very first thing that you need to do is to check whether the SD card or USB drive is locked.
Go and check whether the SD card or USB drive have switches, if the switch is locked, please unlock it.
Method 2. Check the SD Card/USB Drive's Properties
Go to My Computer, click Devices with Removable Storage > right-click SD card or USB drive and choose Properties > choose to Remove write-protection.
Method 3. Disable Write Protection in Registry
- Connect SD card or USB drive with PC, click Start.
- Type regedit in the search bar and click it.
- Select the "HKEY_LOCAL_MACHINE" and click "System".
- Find "Current Control Set" and click "Control"
- Check whether there is a key named "Storage Device Policies" to change the digit in the "DWORD value" box into "0" and press "OK" to save the change.
Note: if you cannot find the key named "Storage Device Policies", you are supposed to create a one: right-click "Control" to create a new key and name it as "Storage Device Policies" > right-click this new key to open "DWORD Value" and name it as "write protect" > Double click it to change number.
- If you are unable to remove the write protection on your SD card or memory card, you cannot format the SD card. EaseUS's free format tool is unable to format a write-protected device directly.
After removing the write protection, you will be able to access the SD card or USB drive. And you can even move data on it. Then you are highly recommended to move all the data on it first and format it.
But if you still cannot access an SD card or USB drive, or you need a more direct solution, you can use EaseUS Partition Master Free to thoroughly format it.
Step 1. Select the USB drive to format.
Connect the USB drive or pen drive to your computer. Download and launch EaseUS partition software. Right-click the USB drive you intend to format and choose "Format".
Step 2. Set the drive letter and file system.
Assign a new partition label, file system (NTFS/FAT32/EXT2/EXT3), and cluster size to the selected partition, then click "OK".
Step 3. Check the warning box.
Click "OK" if you see the Warning window. If you have important data on it, back up the data in advance.
Step 4. Apply the changes.
Click the "Execute operation" button first, and then click "Apply" to format the USB drive.
