This morning my home PC scolded me for moving several directories. Except... I hadn't done that at all. I checked it out and sure enough, my 1TB drive (d:) isn't showing up. Reboots got nothing to change. I powered the machine down, ran errands, came home... and now my machine is stuck on the Windows start up splash screen. I'll give it another 30 minutes before I power cycle the thing.
