Sony India — Sony pendrive is not of any use as it is write protected

Address:	400097
Website:	sony

I purchased one laptop from vijaysales and i got the sony 8 gb pendrive with the laptop .
Pendrive contains mib movie and the pendrive is write protected .
I tried all the process for formatting the pd and removing this readonly property of the pendrive.
Still no go.
I checked on the internet and i found so many users are suffering from the same issue.
This pd is of no use.
Please help if possible .
Otherwise only one way is there that to throw this pendrive .
