I have a seagate barracuda 500GB ES hard drive that I found in a computer while looking around my Dad's office which he had a bunch of broken computers. I don't know what is on the hard drive, because I do not have a computer to plug it in to. I have parts coming in to me today from Amazon, and I am planning to build Friday, but I want to clean install Windows 7, and since it was a office computer, the computer would have a OEM motherboard bounded version on it. I want to empty it completely, so I can have my personal data on it. Is there anyway to do this from the bios, or do I need Windows on the computer to do so? Please help, I am doing this for a school project and its do Monday.
