Let me just give you an idea of what I lost:
ALL 2,000 songs in my music library
My first book, my second book, and the beginning of my third book
All of my short stories
All the pictures that I had before Facebook and that were not shared on my parents' computer
All of my personal work and online quotes that I had found
All of my usernames and passwords.
When I eventually slowed my mind down enough to realize what I had lost, I was blown away and horrified all at the same time. I had just spent an entire fall break making great strides in editing my book. All gone. That was the knife to the gut. I had edited at the minimum-five chapters, and now I had to go back to chapter two. But it wasn't that easy. When Apple recovered my computer and put in a new hard drive, I had to update my software, and the pages that I downloaded was not compatible with plain old word. So after I would go to my "editor elf," and she would send the new copy to me, I couldn't open it on my computer to work on it until I would see her again. My computer crashed October 18. I did not find a compatible pages software until today, December 21--that's over two months not being able to work on my book on my own time. I feel like I have had a dragon-sized weight lifted off my shoulders. So...moral of the horror story...ALWAYS back up your computer. Don't be like me--don't learn the hard way. The hard was is no fun. (But to be fair, the hard drive was six years old...if that says anything of how strong Macs are...)
