How do I clear my harddrive without logging on my computer?

The second way is to access the DOS prompt and use a built-in program called FDISK. You can access it (I think) by just typing cd/fdisk at the prompt. You should look this up before trying it.How do I clear my harddrive without logging on my computer?
