Our family has had the same dell PC for... about 10 years (i think, maybe even longer). Anyway, its been used for general PC tasks, little gaming, internet browsing, etc. It's only been dusted once, about 2 months ago. The hard drive is only 80gb. I asked my mother if she had anything important that she can't "live without" on there. She replied by saying" Yes, I have a lot of important things on the computer, why?" I explained to her how the PC could (and probably will) die at any time. So, what would be a good, cheap, external hdd to back up all of the files onto? It would just need to be bigger than 80gb. THANKS!!
