This morning I took a peek at the content on my external drive. I had been accumulating things, mostly musical performances and space shuttle launches, but a good number of movies and science programs as well. The 2GB drive was about 40 percent full last time I looked. This morning it looked as if there were only a few programs on the drive. So I tried power cycling the drive. Then the receiver showed it was 3% full with 0 recordings!! What?!?! So I power cycled the receiver via the cord. When it finally woke up again, it seemed to have recovered this. There are now 243 recordings, and the drive is 39% full. I can't remember everything that was there, but they seem to be. I spot checked a few and they play normally. I have to wonder - if I had not noticed this and had saved another program from the 922 to this drive, would it have permanently lost everything else?
