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' locking mechanism on the memory card.
Let me explain: many memory cards (or whatever adapter you can insert them into) have a small switch on the left side (label side and contacts facing up), usually marked with writing blocking, which if you are married at the correct address, allows you to enable card write protection.
Taking into account the fact that the switch in question is placed to the side, it very often happens that the block stops write 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 a switch or if, despite having been unlocked through the latter, you still cannot use it correctly, you can try to intervene using the Register Windows, which will disable write protection from there.
So, first of all, connect the microSD card to the PC, inserting it into the appropriate reader and recover the record. To do this, press the key combination Win + R at keyboard from the PC, to open E execute.
And in the window that you see appear on the desktop, type the command regedit. Then click on the button to accept (or press the Enter button on the keyboard) and access the record.
In the new window displayed on the screen, use the folders located in the left sidebar to go to the route HKEY_LOCAL_MACHINE> SYSTEM> CurrentControlSet> Control> StorageDevicePolicies,
Double click the key WriteProtect (right) write 0 in the field Value data and click on the button to accept.
If you can't find the folder StorageDevicePolicies, you can create it by right clicking on the folder control and selecting, from the menu that opens, the elements New> Password. To create the key WriteProtect, then right click on the folder StorageDevicePolicies and select the options from the menu that appears New> DWORD value (32 bits).
Now, restart your PC and try again to write data to your microSD card. If everything went well, you should finally do it.
If neither of the two solutions I have already provided you have proven to be effective in unlocking a write protected microSD card, you can try relying on the tool diskpart, a partition utility built into Windows and working from the command line.
To use it, insert the microSD card into the PC reader, click Start button (the one who has Windows flag ) located at the far left of the taskbar and open the Symbol of the system with administrative privileges, writing cmd in the search field, right-clicking on the corresponding result and selecting the item Run as administrator from the menu that opens. Then click the button yes.
Now that you see the command prompt window on the desktop, issue the following commands by pressing the key Intro on the PC keyboard.
- diskpart - to start the Diskpart utility.
- disk list - to list the units available on the PC and locate the microSD card in which all the permissions will be restored.
- select disk x - to select the microSD related drive you want to act on (instead of "X", you must write the number associated with the microSD).
- attributes disk clear readonly - to erase the read-only attributes of the memory card.
- output - to exit Diskpart.
At this point, your microSD card should finally be unlocked, and therefore should be freely used for reading and writing.
