How to Manually Remove Write Protection from SD Card, USB or Pen Drive

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.

unlock your sd crad, memory card or usb

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.

Notice:
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.

How to Free Erase/Format the SD card or USB drive

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".

format USB - 1

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".

format USB - 2

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.

format USB - 3

Step 4. Apply the changes.

Click the "Execute operation" button first, and then click "Apply" to format the USB drive.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
