@john:: aye, there was about 30GB data for all my games...
i dunno why this happen... i put hirens boot to dvd drive n boot from there,, but when i boot again from windows i got this problems...
@bomberboys: i couldn't click on that partition... it said that the partition need to finish other management task, but i done nothing with the compter managemet...

anyway, i've success delete n recreate the partition using easus partition mgr,,
