When I shut down my system there is audible disc activity and a flickering HD LED at, and immediately after, the point at which the machine turns off. This is scary because I have always understood that turning off power while a HD is active is more than likely to kill it, and I haven't noticed this on other machines. The mainboard is a QDI Advance 5-133E and the O/S Windows 2000 Pro. Is this dangerous? Is there any way I can get back the good old "It is now safe to turn off your computer" message? I would like to get the message back anyway, because I always turn off at the mains socket immediately I shut down, but all I can find online is questions from people trying to get rid of the message!
