It's a writer's worst nightmare... to have a story almost finished, years and years of corrections and rewrites and finally you're almost towards the end until the computer crashes. The hard copy you can find is the beginning of the book, everything else you wrote was on the computer when you were on a roll. You regret not printing out a hard copy every so many chapters. So you may move on to other stories and projects. Then it hits you, you really loved that story, despite the fact that you lost almost all of it. You may not remember what exactly happened page by page but you can rewrite it. This time the story could even be better than the original (positive thinking!). So you start over this time creating a new and great story.
P.S. Also making sure to update your hard copy every so many chapters
