I've got TV plugged into my computer through HDMI and speakers via standard sound cable. Every time I want sound to go into TV, I just plug my sound cable off (socket is on the top face of my tower, so it's not inconvenient) and Windows automatically channels sound into HDMI. And every time my external HDD, which is ADATA NH92, goes dark - it's there in the list of all disks, but I can't access anything on it. If I try Windows just goes into an infinite loop of trying to access it. Only solution is turning HDD off and in (btw, it's connected via mini USB-to-dual standard USB connector).
The same thing happens if I plug sound cable in.
What's going on ?
