Yes, I had the same thought about the hard disk showing warning signs. It has just been a few errors at this point over the last month when I check the diagnostics screen (like, low single-digit write errors). Interestingly, these diagnostic counters appear to reset when you cold reboot the box. They don't return right away, but eventually do. Maybe these errors have added up over time without my knowledge, and now I am unaware how to see the cumulative error count if they have been marked bad by the OS. This is why I'm thinking box swap instead...
All that aside, I tend to doubt that this is why so many people are starting to notice reduced recording capacity at nearly the same time. Maybe I'm wrong, and there is a whole batch of these 320GB Blue WD drives that are starting to have trouble now.
