Ok, I have an old internal hard-drive that I want to use as an external back up drive for my macbook. It's an old seagate ultra ata that has been sitting in the garage for months. The problem is, I can't format it. I can transfer old files off it onto my mac, but I can't add files to it, or modify it in any way. I am trying to format it, and then use it with time machine. Anyone know how to format this drive? Is it even possible to do this?
