How to remove The write protection of Pen Drive or SD Card

As we want to remove write protection, First we should know about the write protection.Write protection is the ability of a hardware device or software program to prevent new information from being written or old information being changed. Typically, this means we can read the data, but not write.

How We Enable and disable write protection using software

To protect a file in the Microsoft windows command line or in MS-DOS use the attribe command. With windows, you can view the file properties and enable the read-only attribute.Finally, with a Linux variant or Unix the chomod command could be used to enable and disable write protection.

Now, I am showing you how to remove the write protection in windows PC detail:

   1.Regedit:

In any version of Windows (from XP), First run Regedit.exe. To find this just Search  ‘regedit’ in the Start manu usually it show at the top of    the list. 

Start manu

Now, navigate to the following link:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Double-click on the WriteProtect value in the right-hand pane. You can now change the Value data from 1 to 0. Then click OK to save the change. Close Regedit and restart your computer. Connect your USB drive again and, with a bit of luck, you should find it is no longer write protected.

You can now continue to use the drive, but it's worth copying off any files you want to keep and then formatting it by right-clicking on it in the list of drives in File Explorer and choosing Format.

 If you can't find StorageDevicePolicies, you can create this by right-clicking in the white space in the 'Control' folder and choosing New -> Key and entering the name StorageDevicePolicies.

Now double-click on the new key (it will show as a folder) and right-click once again in the white space and choose New -> DWORD. Name this WriteProtect and set its value to 0. Click OK, exit Regedit and reboot your computer.

2.Diskpart:

If 1st method doesn’t work, try this method.

At first attach the usb drive or memorycard or pen drive to your computer, lunch a command poromt. You can do this by searching for cmd.exe or ‘Command Prompt’ in the Start menu.

NOTE: run it with administrator privileges. Choose ‘Run as administrator’ from the menu that appears. If you have Windows 10, simply right-click on the Start button (bottom left of the screen) and choose Command Prompt (admin).

Now, at the prompt, type the following and press Enter after each command:

diskpart

list disk

select disk x (where x is the number of your non-working drive – use the capacity to work out which one it is)

attributes disk clear readonly

clean

create partition primary

format fs=fat32  (you can swap fat32 for ntfs if you only need to use the drive with Windows computers)

exit

cmd

That's it. Your drive should now work as normal in File Explorer. If it doesn’t , go to the web of product manufacturer for more support. Sometime SD card or Pen drives have hardware lock system. You can solve it just through unlocking the drive. In the picture is an example of a write-protection switch on an SD card that turns on and off write protect on that card.

Why use write protection?

As mentioned above, by using write protection you can help ensure data is not accidentally overwritten or erased. For example, if you had an SD card with lots of pictures you did not want removed you could enable write protection. Of course, if you were to do this no new pictures could be added.
