I wrote a while ago that I had started using BTSync, a personal file sync program based on the BitTorrent protocol. While it seemed to work well, within a couple of months, all three of my hard drives in three different machines had failed, one after another. I can't be sure it was the fault of BTSync, so it might be unfair to say this, but I suspect BTSync was behind the unfortunate disk failures. For those three hard drives all to fail so completely and so close to each other seemed more than a coincidence. There had to be a common cause. When all the drives were replaced, I didn't reinstall BTSync.
Perhaps my collection of files was bigger than BTSync was designed for, and I overstressed the drives as a result. I'd hope that wouldn't matter, but for reference it was about 65GB of pictures, music and videos. I haven't found anyone else accusing BTSync of eating hard drives like this, so it might not be the cause. In any case, the hattrick hard drive failure scared me off.

PS - I would try to figure out the real cause, but the drives are toast now.
PPS - I'm not sure what I could do with them to find out the truth.
