The HD in question is sitting in a storage container as of now. It is placed in a computer that has been abandoned for a while now due to its condition. The PC would boot up, but it would be horribly unusable due to the viruses. Now... I got a computer that has nothing to do with it. I have been wanting to use the HD in the storage container since I have space for another HD. (The extra GB's would be awesome). The problem is that I don't know what would happen if i put the HD in... Would it harm my new computer if I did since it's full of viruses? If so, can I put it in a "controlled environment" somehow and wipe it clean for future use and with what software? And if I wiped it clean, could I transfer it back to the PC in the container and install my OS from there?
