I just got a Seagate 250GB FreeAgent Desktop USB External HD. The problem is that I don't know what to do with it now. Someone told me that I need to format and make partitions on it before I can use and start moving files out of my overload C drive. But the person who told me didn't have a clue. I've spent the last 6 hours searching the internet for instructions. I see them for everything but external HD and don't really understand what I am seeing anyway. Can someone please walk me through this?
