i am wondering of theres a way of removing everything on a hard drive so that all there is available is space. i have 1 hard drive that has my OS and is currently hooked up. i have another hard drive thats sitting around because its kinda messed up (some kinda virus slows it down big time). this messed up hard drive has an OS in it but i just want to use it for storage now. is there a way to erase everything on it without using disks? ( sorry if this is a duplicate topic. and i dont have much knowledge for computers )
