My drive disconnected earlier as I was playing music off of it with mpd, and would not come back online until I rebooted my computer. Turning the drive off and on again, and plugging it back into the usb port failed to get it working. Only after a reboot did it work again. I noticed a few things in my /var/log/messages that I hadn't seen before. Usually, I just get the first four lines of what I've reproduced below. I'm not sure if what is below is related to mpd or related to the drive, so apologies in advance if this post isn't helpful to the discussion. The details for this drive are given in post #47.
