Removable Disk with Write Protected Status

Removable Disk with Write Protected Status

Probably you might have faced many times, when you insert a USB Flash Drive or Memory Card through a Card Reader in your computer, and when you click on your device, your computer simply fails to explore that portable device and displays a message showing that – This disk is write-protected. This may be sometimes due to virus attack and there are many other causes also. When this happens you can’t copy files to/from your Flash Drive/Memory Card to the computer.

This came to my attention when I inserted my 2 GB Memory Card of my mobile through card reader and found the same problem as mentioned above. However, I have fixed this problem and I am sharing this on TechPuffs for you guys. I am a Windows 7 user, but I am expecting that this solution hopefully should work for Windows XP and Windows Vista also.

How to Remove Write Protection Status?

To remove Write Protection status from your USB drive, follow these steps:

  1. Open Run dialog in your computer and type regedit,  and hit Enter. Now Registry Editor Window will open. In that Window navigate to:
  2. If StorageDevicePolicies is not visible to you then you need to make it manually. To make it manually, create a new key by right clicking on control folder in the left window, and name it StorageDevicePolicies. Now highlight StorageDevicePolicies, and then create a New DWORD (32-bit) Value named as WriteProtect in the right window.
  3. Double click the key WriteProtect in the right window and set the value to 0 in the Value Data Box and press OK button.

  4. Now close Registry Editor window and restart your computer for changes to take effect.

Now insert your USB drive and Windows won’t show it as write protected disk and now you can access this disk onwards.

There is also a little chance that the issue still persists. If this is the case then insert your USB drive in your computer and run the following commands. Open command window by typing cmd in Run dialog and pressing Enter, and type the following commands sequentially.

  1. Type diskpart and press Enter.
  2. Type list disk and press Enter.
