Well, my previous hard drive come with my computer. It is a 6.4gb Quantum Fireball ST. it has Windows 95. Well, I bought a new hard drive, a 6.4 gb Quantum Bigfoot CY, and I installed Win2K on that drive. Now, I am trying to re-format my old hard drive, so that I can use the space on it. for some reason, Win2K is using some part of the old hard drive, and I can't re-format. I am thinking that I can't re-format because it is the drive that the computer boots up on. So, I wanted to make my new hard drive the boot-up drive, so I could see if that is why I can't re-format my old hard drive. I hope this makes sense.
