This is a very very sad day. The HD in my Mystic appears to be kaput. I came in after the weekend to see it at a black screen, with the drive alternately spinning up and down every couple seconds. I tried to reboot and was rewarded with the blinking ? disk icon. I have some spare drives but it is going to be awhile until I have free time to spend rebuilding this system. For now I'll pack it back in its box to preserve it better.
