<1>. You could try some steps on this thread to remove it: http://www.tomshardware.com/forum/296408-32-write-prote...
<2>. Recover your data.
Before the format, you should ensure whether there is something important on your pen drive.
If you do store something important there, you may need a free pen drive recovery tool to get back your data. This free application has helped me recover many of my files from a unformatted drive. You should try it.
<3>. Format it.
If you do not have anything important there, you should forma it :
Start => Setting => Control Panel =>Administrative Tools => Computer Management =>Disk Management=> Right click your drive on the list => format it.
