I recycled the system three times, and the tape drive was still acting odd. It makes your network very vulnerable. The lights came on, but then the server refused to run. We built it ourselves, and I picked the components for reliability. I was surprised by this new problem because I had come to depend on that reliability.
Quality parts fail less often than cheap parts, but any piece of hardware can fail.
Don't depend on reliability. You don't want to hear how I spent the rest of the night testing that server. It was a very reliable drive, the kind that should easily last ten years. The good news is, I got the hard drive working again. The bad news is that I lost everything on it.
