This is apparently just a bad week. Last night, the hard drive with my nearly finished next book along with a few other works in process went belly up. At first I thought the computer itself was toast. It would never come out of POST. This morning, I just left it on and eventually it did come up. Without that one drive. I'm hoping the physical disc is undamaged and it's just the circuitry that has failed. I'll have to look at data recovery options.
A hard drive may sound like a silly thing to cry about, but there's a lot of work on that disc.
