How To Unlock A Write Protected Micro SD Card
Lock / unlock switch
In most cases, unlocking a write-protected microSD card is sufficient to remove the “physical” lock mechanism on the memory card.
Let me explain: many memory cards (or whatever adapter you can insert them into) have a little toggle on the left side (with the label side and the contacts facing up), usually marked with the writing lock , which if you are married in the right direction, allows you to enable the card’s write protection.
Considering the fact that the switch in question is set aside, it very often happens that the block for writing data is accidentally enabled. To solve, therefore, it is enough to simply flip the switch in the opposite direction.
If the memory card does not have any switch or if, despite having unlocked it via the latter, you still cannot use it correctly, you can try to intervene using the Windows Registry , which will disable the write protection from there.
So, first of all, connect the microSD card to the PC, inserting it into the appropriate reader and retrieve the record. To do this, press the key combination Win + R on the keyboard of the PC, to open Execute.
And in the window that you see appear on the desktop, type the command regedit. Then click the accept button (or press the Enter button on the keyboard) and access the record.
In the new window displayed on the screen, use the folders located on the left sidebar to go to the path HKEY_LOCAL_MACHINE> SYSTEM> Current Control Set> Control> Storage Device Policies ,Double-click the Write Protect key (right), type 0 in the Value data field , and click the OK button .
If you cannot find the Storage Device Policies folder , you can create it by right-clicking on the control folder and selecting, from the menu that opens, the items New> Password . To create the Write Protect key , then right-click on the Storage Device Policies folder and select the menu options that appear New> DWORD (32-bit) value .
If neither of the two solutions I have already provided has proven effective in unlocking a write-protected microSD card, you can try relying on the diskpart tool , a partition utility built into Windows and working from the command line.
To use it, insert the microSD card into the PC reader, click the Start button (the one with the Windows Flag ) located at the far left of the taskbar and open the Command Prompt with administrative privileges, typing cmd in the search field, by right-clicking on the corresponding result and selecting the Run as administrator item from the menu that opens. Then click the yes button .

To use it, start by clicking on the icon (the one with a hard drive ) present in the more folder of the Launchpad.
In the window that you now see on the screen, select the name write-protected microSD card from the left sidebar and click the restore / format button placed at the top.
