I have an old Samsung SpinPoint 80Gb IDE drive that would do just fine for backing up my most important files (photos, C# projects, etc.) What I'd really like to find is an enclosure for it that offers one-touch backup of any directories on my laptop that I've specified.
I don't really care whether I'm dealing with firmware or software, but I'd just like to be able to stick this 80Gb HDD is a box, push a button, and it begins backing up "Pictures"... "Visual Studio Projects"... etc.
