New registered user on the forum, and I have a question about purchasing an external hd and thought this would be the place to post. I am in the need of a drive to use for time machine among other things, as I have a 500GB MacBook Pro, and was wondering if anyone had any suggestions. It needs to be Firewire 800, USB, 500 GB or more, and portable. So far I have come up with two posible ideas, and any opinions on the drives I have found would be much appreciated. Links below...
