How Many Lives do Macs Have?

My MacBook is on its third life - or at least, its third hard drive. Last Saturday morning I was reading blogs when it suddenly froze. I had to force quit and manually shut down, and when I started it back up again, guess what? A gray screen with a flashing, question-marked folder. No hard drive. Just like last time. I couldn't believe it. So Sawyer and I spent the afternoon driving to Tyson's Corner for another visit to the Genius Bar (Eric was studying.). I had to leave it overnight, and again they were unable to save anything from the hard drive. It's a good thing I learned my lesson last time and had backed everything up a couple of weeks ago. But I did lose the Enrichment invitations I had designed for Relief Society and my passwords list, which for some reason didn't make it onto the data disk I burned during the last backup. It's going to be a HUGE pain to remember and/or request replacements for all those passwords. But hey, at least my ginormous iTunes library is safe! My next purchase: an external hard drive so I can back up more frequently. I hope if it's going to die again it happens soon, because the warranty expires in July.
