Loyal readers may recall that the hard drive on my MacBook crashed last summer when the poor thing was only about 3 months old. It got replaced for free, of course, but I did lose some data and e-mails. I now back up daily. But the same thing just happened to one of my colleagues, and she lost something like three years of data. It was the same batch of MacBooks that mine was - we got ours from the university at the same time.
Are Mac hard drives are somehow more vulnerable to crashes than PC hard drives? That certainly wasn't my impression, but it strikes me as a fishy coincidence that two MacBooks in the same office have crashed irreparably within their first year of ownership.
A further question: hard drives are especially vulnerable to sharp jolts, which is why you should never move a computer when it's hard drive is spinning. Why, then, is it okay to go jogging with an iPod? That little hard drive seems indestructible. So my book project is always in danger, but my Go-Gos music will apparently never die.
