Two Years exactly is what I lost. TWO YEARS. Two years of videos and pictures of my kiddos. I didn't back up any. Didn't print any. Luckily for me I have a blog that has all my favorite photos of the last two years backed to picassa. I think that is the only reason I didn't have a complete meltdown. I started to upgrade my computer to snow leopard so I could download ilife. And bam- corrupt files were found and my hard drive crashed. Immediately took it to Apple who had me go buy an external hard drive. They tried for five days to fix it and finally called yesterday to say my computer was ready but they had to put a new hard drive in. Nothing was saved. So, I am sending my old hard drive off to some place in California that will hopefully be able to salvage something for me. But I am sure it will be a pretty penny. Sometimes I really hate technology.
