Moser Baer pen drive disabled

Hello,
Sir,

I have a Moser Baer 1 GB pendrive. It showed 2 partitions - a partition which had a password protection software and another where i could keep my data. I used the password protection tool and locked the other partition. But mistakenly, also formatted the partition containing the password protection software. Now, it shows insert disk in drive --- and does not format.

Please help me out.

Thank you.
