hi........please check that if there is switch in your pendrive..if present turn it other side..if not than follow this steps... 1. download a software from here http://www.softpedia.com/get/System/Hard-Disk-Utils/HDD-Low-Level-Format-Tool.shtml
2.now fromat your pendrive by this software and than scan it for virus ...
hope this will solve your problem

your pendrive is infected with Autorun.inf virus
to remove this virus install malwarebytes and scan your whole system as well as your pendrive

If the above method is not work

try to format in other operating system like vista or in 7
but not in xp because in vista and 7 you can force format your pendrive..

I have had the same prob and able to remove the write protected message by just unlocking the hold button. If this doesn't work there is formating software for each USB on the web. One can google and download it for free inorder to formate the USB

Think this write protection error is due to some virus.
