How to Remove Write Protection from a Drive or Memory Card?

<1>. Remove it by sliding the switch on the one side of a drive or memory card.

 You could firstly check whether there is a switch on the one side of the drive or memory card, the switch that can generally close or open the write protection function.

Fortunately, if you find such a thoughtful switch, you could freely slide it to lock or unlock the write protection.

However, if you don’t find such a switch, don’t worry!

<2>. Remove it by plunging the drive or memory card to a computer.  

Unluckily, if there is no such a switch or the switch is gone, you also could try to remove the write protection by yourself.                  

1. Plunge the drive or memory card to a computer. (Of course, you should use a card Reader to connect your memory card.)

2. Click “Start” on the taskbar to open “Run” and type in “regedit”.

3. Hit “HKEY_LOCAL_MACHINE” to expand “System”.

4. Find “Current Control Set” in “System” list to click “Control”.

5. Check whether there is a key named “Storage Device Policies” to change the digit in the “DWORD value” box into “0” and press “OK”.

But, 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 highlight “DWORD Value” and name it as “write protect”=> Double click this “write protect” box to change the number.

<3>. Remove it by trying some special software.

There are many related special software out there. You should make your decision carefully.


“Read-only” & “Write Protection”

As to a “read only” drive or memory card, “read only” is absolutely another description for people to deliver the same meaning of “write protection”, especially for some computer beginner.

Therefore, in this situation, we could cope with the “read only” problem in the same way as the “write protection” problem.

However, as to a “read only” file or folder on your drive or memory card, the “read only” is quite different from “write protection” in some degree. It is only one of the file or folder attributes, not the whole drive or memory card attributes. Namely, we still could do some changes to the rest files or folders on our drive or memory card after part of files or folders become “read only”. However, we cannot do it to the write protected drive or memory card. That’s the difference.

Therefore, in this case, we could simply remove the “read only” like this:

Right click the file or folder to hit “Properties” and remove the sign in front of “Read only” attributes in “Properties” box.
