I recently bought a Seagate FreeAgent GoFlex, 500GB in order to back up a few things on my computer and so it could go a bit faster by freeing up some space on my hard drive. I was wondering what the best way to go about it would be. Last night I backed-up my whole computer, but I just want to save my pictures, videos, music and documents. Should I erase everthing else or do you think its a good to backup the whole computer? Also, Im going to format my computer, so I was wondering when I plug the external drive back in, does it erase the documents that aren't there anymore, or does it just leave it and add the new ones that I dont have on the external? Do you have any tips for me?
Thanks in advance for your help!
