My 6 year-old PC (XP home) feels as though it is it's about to give up one of these days, maybe soon. I have lots of files (music, video, photos plus the usual documents etc which I do not want to lose. Please tell me the best (ie fastest, saftest, simplest) way to back up what's on my hard drive. I've thought about an external hard drive - is this the way to go - or what? Thanks folks!
