I'm not sure whether or not this is a stupid question, but is it a bad idea to buy a used external hard drive? I'm not sure if it is truly used. I am buying one off Craigslist and the person says it is brand new, but in the case that it isn't I was wondering if that could somehow hurt the performance of the drive. Granted it isn't damaged in any way. Obviously I will be able to tell if it has been opened, but I wasn't sure if I should be wary of buying a used one. It is a great price. http://raleigh.craigslist.org/sys/2452807244.html Got them down to $40 on it so I figured why not. Please tell me what you guys think. Thanks.
