FORMAT PEN DRIVE

Hello,
I recently purchased a 64 gb pendrive (Kingston) . I tried to format it, but during formatting its file system is only NTFS but not formatted at all. It is not opening at all, showing the "disk is not formatted". When I am triyng to format it in NTFS it is showing pendrive cannot be formatted. I have also tried HP USB disk storage format tool 2.06 but it still not working in any format NTFS, FAT or FAT32.

Please helpme to overcome this problem.
