Sounds a little risky I know. My old laptop was ruined because of viruses. So, i made a desktop computer. I do have a lot of Gb's for storage on this computer, but i could always use more. Before i got rid of the laptop, I stripped the Hard Drive from it. I couldnt wipe the drive, or re-format it because i had already threw away the laptop. I would really like to use the hard drive, but Im not risking using a virus infected hard drive in this computer. Im not sure what to do. I know old fashion methods of wiping hard drives with a magnet, but that would probably destroy the hard drive, which would defeat the whole purpose. So, how do i wipe the hard drive clean, so i can use it on my new computer, without infecting my new computer with the viruses on the hard drive?
