Remove write protection fro flash disk and sd card

Method I : 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 diskpart command can do serious damage if you run it on the wrong disk. 1) Start Menu -> Run(or in search box) -> Type 'cmd' -> press 'Enter' -> Command Promt will open 2) Type 'Diskpart' -> enter -> 'list disk' -> enter 3) Select the disk you are going to modify, if your required USB disk is in 'disk 4' then 4) type 'select disk 4' -> enter , now disk 4 is selected, 'list disk' will show star(*) beside it 5) 'list disk' -> enter To Clear the Read-Only attribute on the selected disk (To Disable write protection): 6) Type 'attributes disk clear readonly' -> 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 readonly' -> enter When you are done modifying the disk attributes just issue the exit command 7) 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 II : 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.
