Yeah, I saw that, so it's actually an SSD (the wretched samsung one I've
been posting about), and I'm just about to return it.

What's interesting is that smart shows no such error:

I'm not saying nothing is wrong with the drive, but that it's not a magnetic
bad sector.

Either way, I'm going to get a different SSD soon, although I guess this faliure mode
was useful in finding a bug in the btrfs code in the meantime :)

Thanks for the heads up
Marc
