But for the longest time, it was a bit out of my price range due to other priorities. Actually, the whole model line was defective, so they are sending me a new one, and I have to wait for it to arrive. > Without a UPS nothing can protect you against power outages.

If the > power fails when a write is in progress, you're screwed. I'm aware of nothing but a UPS can completely protect me from an outage. I was just wondering why that ONE file system was misbehaving, and the rest are prefectly fine - which seemed odd. Additionally, why were files that are read, but not written, being lost? I can understand losing files that are being written, but if there's a file that has bene written several restarts ago, not written to thereafter, and has been fine ever since, why is it being lost now?
