How to Disable Write Protection From Pendrive

What is Write Protection?- Write Protection is a feature (yes you read it right) that is generally
found in flash drives like pen drives and memory card. It prohibits user to write anything to the drive, thus protect the drive from any modification to its data and also stops virus (from computer) to Copy (write) it self to the drive.

- How to Solution this problem

Update: I have found a simple trick which also solves this problem
(when your USB Device has minor problem only). Trying this:

1. Right Click My Computer

2. Click Manage 

3. Then Click Disk Management

4. Select your USB drive.

5. Click "Change drive letter and paths"

6. Then  Rename it to a different letter
Check whether it starts working or not!!


Method 1: Using Diskpart

First we will try to remove read only attribute from the specific drive.
Warning: Be sure to do this on the right disk since the disk part command
can do serous damage if you run it on the wrong disk.

1. Start Menu-> Run (write search box) Type cmd-> press Enter Button.
2. Type diskpart >  Enter
3. Type list disk > Enter
4) Select the disk you are going to modify, if your required USB disk is in 'disk 4' then
5) type 'select disk 4' -> enter , now disk 4 is selected,  'list disk' will show star(*) beside it
6) 'list disk' -> enter
To Clear the Read-Only attribute on the selected disk (To Disable write protection):
7) Type 'attributes disk clear read only' -> enter
The disk is no longer Write protected. The Read-Only attribute is removed.

If you wish to set the write protection again, just do the same procedure and
Type 'attributes disk set read only' -> enter

When you are done modifying the disk attributes just issue the exit command
8) Type 'exit' -> enter

If files inside USB drive are still in read only mode
-open command prompt
-Type ' j: ' -> enter (put your drive label in place of 'j' )
- Type ' attrib -r /s /d *.* ' -> enter
- exit


Method 2 : Using RegEdit

This will Remove write protection from USB Drives. If it doesn't then lets disable writeprotect from your System Using Registry Editor:

1) Start Menu -> Run(or in search box) -> Type 'regedit' -> press 'Enter' -> Registry Editor will open

2) Expand by clicking ' + ' and Navigate to the following path :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

If you can't find  'StorageDevicePolicies', then you have to create the key:
-Right click on ' control '-> New -> Key -> a new key will get created -> rename it as 'StorageDevicePolicies'
-Right click on 'StorageDevicePolicies'
-> New -> DWORD (32-bit) Value -> Name it as 'WriteProtect'
writeProtect to storage device policies   

Now if you want to enable write protection, use ' 3) ' , to Disable write protection, use ' 4) '
3) To Enable Write protect, Double click on 'WriteProtect', and set its value data to '1'
Edit DWORD value
Once set, all users on the computer is now blocked and prevented from copying, transferring or writing any files, documents and data to the USB disk drives.
4) To Disable Write protect, Double click on 'WriteProtect', and set its value data to '0'
Once reset to '0', all users on the computer is now allowed to copy, transfer or write any file, document and data to the USB disk drives.

5) close your registry edit window.
For first time, you may get that same message again, close the notification window and try to write to the USB again and it should work. You’ll probably have to do this with all your USB drives to clear that “Disk is write protected” message. Hope this helped.

If still same problem then You have to go for Formatting it.
