Need some help formattion HDD.
So i've got this 80G HDD i used in my desktop a while back, when my desktop went nuts i just turned the HDD into an external HDD for my Mac. Now i've got new parts for my desktop and i want to use the 80G as the main internal HDD in my desktop, how do i reformat it back to Windows?
Edit: Sorry for the typos, currently doped up on cold medicine.
