Hey Andy, I've got a question: I went to analyze your raw data dumps and saw a couple of things that I wanted to understand: * A hard drive may go missing in the data from one day to the next without appearing as "failed" -- does this mean you've taken these hard drives offline for some reason? * A hard drive may appear as failed one day, and then appear the next day with a failed=0 flag. Does this mean that these drives have been serviced and returned to the front lines?
