So I am thinking about a new PC build a lot now due to it being quite close to Christmas and I was thinking about using a 120GB Kingston SSD for the OS. I of course want to use my 500GB HDD in the PC but I currently have windows 7 and a load of games installed on it. I want to completely wipe the HDD for the new PC. But how do you actually wipe/format the drive? If someone can tell me I would be grateful. Thanks.
