I am thinking about partitioning my 2TB external HD. I use it for TM, and I don't need it to be nearly that big (internal is only 500GB). I figure 1TB for TM and 1TB for photo storage would be nice to have. I want to clear off some of my internal HD as it is starting to get too full. I know I would lose whatever data I have saved already, but that's not a big deal. I assume I would use Disk Utility to help me. Any advice or anything for me to be aware of? Any "got yah's"?
