i just finished building a desktop pc and installed the os on a samsung evo 840 500GB, well everything went smooth. now, i also dropped a 1TB HDD in my pc and when i started my pc, i didn't see recognition of my new HD in "computer" folder. however, when i went to the disk management, it shows the disk as unallocated but it shows the disk with the volume and info, no problem. my problem is to format this disk and use it as storage in my new pc, i don't see any option for that. does anyone know how to format this disk and make it usable? i am using windows 7 professional in my pc! i appreciate your help.
