"The Disk is write-protected” problem in Memory Card? Here is Soloution

Recently when I tried to copy some files to my mmc using
card reader it showed me some error saying the 
disk is write-protected. Remove the write protection or 
use another disk.

It was working fine before.

I have used this card many times before but it never gave
any error and suddenly it started showing this error. 
After going through some forums I came to know that it 
happens because of write protection notch but there was no 
such notch or switch on my card.I kept on searching on more 
forums and after some time I found one solution to this problem. 

Follow the steps given below if you are also facing the same problem.

   1. Run Registry Editor (regedit).

   2. Navigate to the following registry key:
      (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl)

   3. Right click on control and create new key.

   4. Name it as Storage Device Policies .
      (Copy and paste it from here if possible)

   5. Now click on Storage Device Policies and in right
      side pan right click and select create new dword
      and name it as Write Protect.

   6. Double click on it and set its value to 0.

Now restart your machine and try copying some files to your card.


If this thing also doesn’t work then keep your card in card reader,
connect it to your PC and then restart your system. I don’t know the
logic behind this but It worked for me.

Comment if you need any help.
