Well, my number came up today. The hard drive in my MacBook Pro started making this funny crackling, clicking noise. The Finder beachballed. Xcode locked up. I tried to shut down the machine gracefully. Tried to force quit everything that wouldn’t quit. No luck. Power cycled it. It booted to the blue screen, then hung there.

Funny – just two days ago I was visiting my uncle in Colorado, talking with him about statistics and probability, the Gambler’s Fallacy, and the reliability of hard drives. Now TechTool Deluxe tells me my drive has a bunch of bad blocks in the middle of what used to be my data. I guess I asked for this – bad karma.

So I’m going to lose some development time. That really, really sucks. But it doesn’t suck half as much as the prospect of losing all my source code, email, customer databases, test files, scripts, music, and geez – all my photos too. Thankfully, I’m still fairly paranoid about backing up (not as paranoid as I used to be, but still enough that I’ve got a backup in my office from last night, and an off-site backup from last week).

So look at all those files on YOUR Mac. How would you feel if they went away tomorrow? Like really. Y’know – gone, * poof *, never to return. The old adage is that it’s not a question of whether your hard drive will fail, but when. I’m happily calm about my bad day. At least it’s not a Bad Day with a capital ‘B’. Sure, it’s a maddening setback, and I’ve lost a little work – but I haven’t lost everything.

Do yourself a favor. Back up your data. And yes, I mean now. Get SuperDuper!, Time Machine or some other (lesser) backup application and use it. Sometimes it’s a nuisance, but right about now, I know it was a good idea.
