I don't think that it is a bad drive either. It seems more like a duplicated bad write, as you suggested. If you look at the array status in the web interface, does it show up as healthy, degraded, or something else?

I would be interested to see what would happen if you replaced drive 1 with a different drive (by drive 1 I mean physical drive 1...it would be drive 0 according to the snap). I'm wondering if when it re-installs the OS to it and rebuilds the RAID if it corrects your error. That's what I'd do, but I will admit that I don't know for sure what is going on and this is not a "fix" that I know for sure will work. It's just what I would try on my own.
