Remove Write Protection From USB Drive Problem and Complete Solution

If you are using Windows 7 OS and can't find the way to disable the write-protection to your USB drive here is the full tutorial:

After connecting the USB drive, you probably received the error:

The problem: The disk is write-protected:


1. Check your cables, is the drive connected properly?
In some cases, the problem can be fixed quickly. Just check the cables first and you may notice that the drive was not connected properly. Once it is connected properly, you will be able to write to your USB drive again.
Note: In some cases you can read the drive even if it is not connected properly.

2. Is the drive actually write-protected?
Open the Windows Explorer (Windows key +E) and right-click on your USB drive and click on Properties. Go to the tab Security and click on Edit. Select your username and check if you have Write permissions. If you don’t, check the option “Full” for full permissions or “Write” for write permissions:

3. Search for a “lock switch”
Some USB drives and USB sticks have a switch that allows you to lock a hard drive and prevent ANY changes. Please read your handbook or examine the USB drive, SD card or USB stick closely. If you can find the switch, you can easily unlock and remove the write protection from your drive.

4. Modify a registry key: StorageDevicePolicies
The last solution that you might want to try after creating a backup of your registry:
1. Click Start, type regedit.exe and hit ENTER.
2. Go to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\StorageDevicePolicies
3. Search for a key WriteProtect
4. If there is such a key change the value to 0.
5. Repeat the same for all HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00*\Control\StorageDevicePolicies (replace * with number)

4'. Can’t find (3)? Create a registry key StorageDevicePolicies:
If you can’t find the key StorageDevicePolicies in step (3) you have to create it manually:
1. Right-click HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\ and select New -> Key.
2. Enter the name StorageDevicePolicies.
3. Click on the new registry key StorageDevicePolicies and on the right pan right-click, select New > DWORD and give it the name WriteProtect.
4. Double click on it and set its value to 0.

5. Last resort: Format your USB drive
If you still receive the error that you have to remove write protection first, try to connect the USB drive to another PC and see if the problem remains. As a last resort, you might want to copy the data on your drive or stick to another USB drive and then format the write-protected drive. After formatting the USB drive the write protection will be gone.
