There is an easy way to Remove Write protection from pd.

Steps:

  1. Open cmd as administrator
  2. Type some commands
    1. diskpart
    2. list disk
    3. select disk 1 (flash drive disk)
    4. attributes disk clear readonly (or to set -- 'attributes disk set readonly')

There may be 3 possibilities

  1. your pen drive have a physical lock and if it is enabled make sure to disable it
  2. try to format it with windows and if it does not allow you use "DISKPART" (it is run from command prompt for its commands google it ) to format it
  3. Use a LOW LEVEL FORMATTING TOOL to format it
  4. If above methods are not working , Use DISKPART to check the status (the drive is read only OR not) and if it is showing "read only : no" your drive has a hardware problem contact service center

It's been a long time since you asked but to help others, I just did some deep hacks (ChkFlhs lol) and killed my sandisk which was write-locked, it was kind of a vegetable though,

In the sandisk forums someone sais that he contacted sandisk and they answered,

I understand that you are getting write protection error while accessing your Cruzer flash drive. The flash drive has detected a potential fault and has become write protected to prevent data loss. There is no method to fix this. You will need to backup your data and replace the flash drive. Our team of developers is in combination with the OS developers looking into a solution to resolve this issue. Please note that only a minor percentage of users are experiencing the write protection issue and these are the customers posting on the internet to find a solution.

He also sais,

SOLUTION 1: Return to where you bought and get a refund (as others usb drives might have the same issue) SOLUTION 2: Contact Sandisk costumer service and get a refund, for the same reasons

Good luck sending your flashdisk to sandisk :)
