I think my computer is about to die any second. The whole noise problem listed here http://forums.macrumors.com/showthread.php?t=174127 has just gotten worse. It's so bad I can't even move the computer off from the desk. It'll start screaming. It's so loud and sensitive. So I'm trying to back up everything so I won't have a crying hissy fit. Which back up external HD (for really cheap- under $100) do you guys recommend? All I need is 100 gig or less. 80 will even do. However, I am paranoid that the external HD will break while housing my most treasured media... so something that won't die will be great.
