Hiya, I plan to move to China over the summer for work and am trying to digitize my life. I have a 2007 Macbook with 1GB of RAM -- I've already been to the Genius Bar at Apple to discuss RAM options (I'm going upgrade to 2GB), but now I need to figure out my external HD I currently have 500GB external HD that I use as to backup files through Snow Leopard's TM. It connects with a USB, but still needs to plug into a socket for power. I know I would need an adapter and an electricity converter (any suggestions?) My main concern is getting another external HD to store files onto. I am a teacher and I do not want to lug all of my (paper) files across the world, so my plan is to digitize everything before I go. I assume I'd only need 500GB to do this -- any suggestions as to a brand? The other HD I have, I received after I almost lost my data when my vault malfunctioned; the Apple customer service rep sent me an HD, so I don't actually know/remember the brand as I didn't do any research for it ... I really just need to figure out the best external HD option that I can take with me when I move; compact & somewhat lightweight. Anything else you think I might need to function abroad would also be appreciated Thanks for any and all advice!
