I have a Dell Inspiron 1100. I have been plauged by all sorts of problems lately, and I had to reformat twice in the last 4 months. I am getting a little sick of loosing all my important files. It is time for me to consider backup options. I will need approximately 40 GB of backup space. I assume this places me in the market for an external hard drive. I will not want to back up my entire computer, but only my documents, pictures, mp3s, videos, ect. Does anyone have a suggestion for me?
