I have Toshiba 8 GB Transmemory USB and my OS: Windows 8.1 Pro. OS is detecting the drive and showing the memory. but OS and other third party softwares could not format the disk and sometimes showing 0 MB memory and could not be formatted. also sometimes as write proteced. pl help me how can it be formatted?

If it truly is a "write-protected" problem, try step 6 here: http://www.makeuseof.com/tag/how-to-fix-write-protection-errors-on-a-usb-stick/

If that makes no difference, the pen drive probably has corrupted memory chips so throw it away and buy a new one (not Toshiba, they are no longer a quality brand like they used to be in my opinion. Started going downhill about four years ago, cutting manufacturing costs to compete with the cheaper brands).
