Computer Security Story

Unfortunately I have several computer horror stories to share. The worst one I have had to deal with was when I was a junior in high school. I was using the family computer to write a 10 page research paper for my English class and I did not back the paper up on a disc. I was up to the 8th page of writing when the computer froze and I lost everything I had written. I had to rewrite the whole paper 2 days before it due. (Turns out our hard drive crashed, it was a really old computer. I also blame my brother who had multiple online games downloaded to the computer). Since that day I've backed up all my files multiple ways (through flash drives, discs, etc).
Another story I have is from a friend of mine. Her computer crashed junior year of college and she had not backed up any information. The computer service people at Tech said her hard drive had crashed and they could not recover any of her music, photos, documents, etc. She lost everything. She replaced the hard drive for $100.00 but she probably lost hundreds of dollars of music from her computer. Now she has a new hard drive and an external hard drive that she backs up all her files on every week.
