Although the computer came up one more time as I wrote last night, and while I got as much of my settings off of it as I could, it was the last straw. The next reboot wouldn't boot, and my attempts at fixing it totally hosed it. It won't even boot into the recovery partition now. It's utterly hosed, and thanks to the encryption software, it's effectively bricked as a hard drive. We'll have to reimage it and start over next week. I hope I can manage with my personal machine for the next few days and that I haven't managed to lose anything irreplaceable.
