More than 15 years ago, the house I was renting with a couple of roommates was burglarized. The thieves stole the usual kinds of things—CDs and other stuff that's easy to fence—and included among that was my Nikon FG SLR and lenses. I had insurance, which replaced that camera with the early-'90s equivalent, the F-601.

The new camera came with a pretty decent Nikon lens, a 35–70 mm zoom. But a few months after I got the camera, the zoom ring on the lens became loose and didn't work properly. I sent it in for warranty repair, and then used the lens through two additional cameras (another F601 I bought after the original got dropped, and my current D50) until last spring.

That's when the zoom ring started misbehaving again, and I replaced it with a new Nikon lens, an 18–135 mm zoom that has worked very well for me, and is usually the kit lens for the higher-end D80 SLR. Until the past few days, when the zoom intermittently stopped autofocusing properly. The barrel of the lens also started to feel a bit loose. So I've sent it, like its predecessor, off to Nikon for repair.

I supposed there's a reason the lower-cost lenses aren't as robust as their professional siblings, but it's not like I abuse them. And that old lens did work great for me for a decade and a half after its initial repair. I still have it downstairs, in fact. Maybe if I can get it to behave I can use it while the other one is in the shop—but there's really no need. I have three other lenses that seem to be working just fine.

Recently, pioneering web developer Dave Winer became upset with Apple because he took in his laptop for warranty service, the Apple Store replaced his hard drive, and then the store wouldn't return his old drive to him, even when he offered to pay for it. After complaining enough to Apple and on his blog, he eventually got the drive back.

The reason he was upset was that his old drive contained a lot of his property, including source code, personal information, and so on. He was worried that Apple's keeping the drive risked that data, because they planned to refurbish it. There could be a security problem from that, including the possibility of identity theft if anyone ends up getting at the information on the disk:

What if the data on the drive can be recovered? What if there are credit card numbers and other personal information on the drive? Source code? Trade secrets?

Now, as I've noted before, Mr. Winer can be a cranky sort, so when he complains, it's wise to look at the problem carefully before deciding whether you agree with him. Some, including Matt Deatheredge (via John Gruber), initially argued that:

If the computer that needs to be repaired has sensitive information on it, I back it up and wipe the hard drive, restoring the default system on it.

Many people, including me, emailed Matt with variations of this point: If you take your drive to Apple (or anyone else) because it's died from hardware failure (which is presumably what would be covered under warranty), you might not be able to erase it. And if you take superhuman security efforts as some recommend on a dead drive (big magnets, drilling holes in the platters), Apple is going to say, "We won't cover this—you destroyed the disk."

Now, the risk of people poking around on your dead hard disk is mostly theoretical, although it is possible and has happened. And no one is yet sure whether Winer's disk was actually dead, or could have been resurrected enough for him to erase it before he sent it for repair. As Deatheredge notes in a big update to his post:

What happens if the drive is so damaged that you can't erase it at all? This case [...] seems genuinely problematic.

The real solution, other than for Apple to offer to give you your drive back (even for a fee), would be to encrypt anything important on your disk, or the whole thing, but few people do that. I have done it for some of my information, but not all, and when my MacBook drive died last year and I sent it back to Seagate, I was unable to erase it first. I'm not worried, but if I were paranoid, I might have eschewed a warranty repair, bought a new disk, and destroyed the old one myself.

But I didn't. Ooh, living on the edge.

I was a bit disturbed this morning when I sat down on the porch with my MacBook and saw a strange bright blob in the middle of the LCD screen. I thought the display might be damaged, but when I moved the laptop the spot went away.

Then I realized that the spot was actually the light of the sun, which is so bright that it is shining through the translucent Apple logo on the back of the lid, and illuminating the centre of the screen from behind. (Normally the logo is lit up the opposite way, by the lamp from the LCD panel.) I guess you could call it a design flaw.

It turns out that my dead hard disk is still well under its five-year warranty, and that Seagate, the manufacturer, has an efficient online return system that helped me diagnose and then set up a return merchandise authorization (RMA) for it, including printing a shipping label for me.

So rather than go through the rigamarole of trying to rescue any data from the drive (as far as I can tell, it's not even spinning up), I mailed it off to Ontario a couple of days ago, and Seagate will send me a new replacement that I can drop in its place. In the meantime I'm using the stock MacBook hard disk, and it's working fine.

Because of my backup regimen, I lost so little data that all I've had to do is go through a few pages of my Flickr photos and re-import the missing ones into iPhoto—nothing else critical is missing. At least not that I've discovered so far.

So I should have a new drive to put into the MacBook next week, and I can use the one I have now once again as an external backup. One thing I do need to do is take some of my recent backups offsite, because right now I'm protected against failures, but if we get burglarized or the house burns down, important data could still be at risk.

You should do the same with your backups. You do have backups, don't you?

I thought that a few months ago, when my MacBook laptop finally returned from getting a new heat sink, fan, and battery, it would be stable. But no. Today I was working away, just having uploaded a bunch of photos to Flickr, when the MacBook froze up, which is unusual. I rebooted it.

Click click, said the hard disk. No booting. Grey screen, as if there were no disk inside at all. Not good. This disk is completely invisible to the utilities I own, as if it wasn't even there. I have backups, and very little data on the drive doesn't exist somewhere else, so that's not my worry—I learned my backup lessons years ago.

But it is certainly annoying. The 100 GB, 7200 rpm SATA disk drive is just over a year old: I installed it when I bought the MacBook, putting the stock drive in an external USB housing. It should have lasted much longer than this, but I suspect that all the nasty sudden power shutdowns with the battery problems I had may have damaged it, so that it decided to die today.

I'm typing on the MacBook now, having restarted from my external FireWire backup drive. I've reinstalled the original stock 80 GB, 5400 rpm hard drive and am copying over my data files so that it will work again. It should be in relatively normal shape later tonight.

But I'm not giving up on the bigger, faster drive yet. I don't trust it, but I want to see if I can bring it back to life again. The excellent DOS-based utility SpinRite apparently performs miracles on dead drives like that quite regularly. My dad owns a copy, but it's not intended to run on Macs, and sure enough, when I tried booting his CD on the Intel-based MacBook, it started up fine, but did not recognize the keyboard, so I couldn't do anything.

I'm going to see if I can get a SATA-to-IDE adapter to hook up the disk to one of my dad's Windows PCs, which will run SpinRite and may be able to get the disk working again.

Regardless, I will probably have to get another new internal drive (maybe a bigger one now, 160 GB or 200 GB) as the main one for this machine in the long run. I like this laptop and it has done great work for me, but it's sickly, to be honest.

One problem with digital SLR cameras (DSLRs) is that, because their lenses are interchangeable, and unlike "sealed" point and shoot cameras that most people have, they're prone to accumulating dust on their sensors, which can create spots on the images they take. I actually had to return my first DSLR because it came with such spots, rather than developing them slowly over time as is more normal.

In the old days of film, dust wasn't as much of a problem because every time you changed film, you changed the sensor surface. That's also why film cameras could remain useful for decades—you can use modern, higher-tech film in a 50-year-old camera with good results. With digital photography, to upgrade the sensor surface you have to replace the whole camera. That's one reason extremely expensive digital cameras like the Leica M8 are more fetish items than wise purchases.

Anyway, Macworld has a useful article on some tools to help clean dust from DSLR sensors. That includes magnifying loupes, cleaning solutions and brushes, and so on. It's an iffy process that could void your warranty, so it might be wiser to have a dealer do it rather than trying it yourself. I don't need to yet, so we'll see what I decide when that time comes.

My MacBook is officially one year old this week. Despite our somewhat checkered history over the past 12 months, it is now behaving as it should and is doing a great job with all the stuff I throw at it.

Which is, I guess, more than I can say for my own body these days. I'll be taking myself into the shop in a couple of months too, so both the MacBook and I will have seen major repairs in 2007.

I hope my own goes just as well.
