It is possible the computer's power supply was on its last legs, and a small voltage dip caused it to fail at JUST the wrong time. Good hard drives are quite reliable, too. I had a cheapie Chinese adaptor to go from 4-pin Molex to SATA power, and it was dropping +12 V at least once a day for over a week before I figured out what the problem was. No damaged data, to my amazement. I guess as long as the +5 stayed up, it wrote out whatever was in the buffer when I jiggled the cable and got the +12 V back on.
I had my mains power go off long enough that I was reaching for a flashlight until the power came back on. It must have been a little less than a full second, but pretty long in computer terms. I was machining a part at the time, and the computer, servo drives and spindle drive all kept running right through the outage! That's what they are supposed to handle.
