I have a 500 gb westec hard drive that used to be on my computer. When I downloaded a bios for my computer it no longer worked. So I installed my 250 gb hd back onto my computer and everything is fine. My ? is: Can the 500 gb hd be saved and used again? Maybe a 2nd hard drive or anything like that? is there a way to reformat it I guess is a better ? to ask? It had more memory on it than my current 250 gb one does so it ran a lot faster for me.
