Hey check this.
I had this problem too on a drive that does not have a write protection switch
I tried many things (RegEdit, DiskPart, using GParted under Linux etc...) without any luck.
The next thing I tried was re-flashing the USB drive firmware and that worked.
It is quite involved, as you need to figure out the vendor ID and Product ID of the drive
This software allows to detect all USB devices and find ID:
http://www.nirsoft.net/utils/usb_devices_view.html
the download is all the way at the bottom or here: http://www.nirsoft.net/utils/usbdeview.zip
Then you need to go find the Mass Production tool software (the program manufacturers use to flash and test the USB drives)
The best place seems to be here:
http://flashboot.ru/iflash/
Enter the VID (Vendor ID) and PID (Product ID) and if you're lucky there is a tool for you!
Look for the CHIP vendor (not the flash vendor). Mine was Phison. And then the Flash MODEL
Then go look in the tools section: http://flashboot.ru/files/
and find the flash vendor tools: look for the tool that supports your Flash model.
Once you have that, you may need to look up info on the web on what to do because all tools are different.
One thing seems to be common: you can load the current config and save the data to disk: DO THAT FIRST!
You generally then need to edit some paramters: make sure they match what you currently have.
In my case with the Phison tool, the tool version itself and some DLL version were wrong, and not available. I 'downgraded' the version numbers in the program to match the flash tool I had, and it went through.
TADAAA!!! Now I have a brand new flash drive unlocked... but obviously EMPTY... So if you have important files on there, you should really back them up first (as usual!)
Good luck!

Again, these are all solutions for Windows users. I need a solution for a 64G drive (to hell with the data on it!) for a Mac. I originally formatted it for ExFat and that worked until I let a Windows user borrow the drive. It came back as write protected and cannot be reformatted using the OS X disk utility (reformatting greyed out). There is no write protection on/off button. What is the answer?

I have an 8GB Mentor media sent by Dell to install Windows 8 on a replacement HD. When tried to write to it or format got the message "write protected".
This will surely fix the problem. Download this utility from the link and follow the simple instructions by launching the program ( .exe file )

Working as of Jan 8th, 2015

By the way the USB is pretty cheap, write speeds are about 4MB/sec and read about 19MB/s, but it was free from Dell and you can use it for whatever you want where data access speeds are not a concern.

Have fun!


Cheers

Unless you specifically enabled a feature to write protect the thumb drive (which very few support) the issue is hardware related.

First check the capacity as shown in drive management (ctl panel > admin tools > computer management > drive management) to see what it's showing. If it shows 0 as the capacity (which it most likely does) then the drive is toast and the data is most likely gone.
