Without warning one of my three internal Seagate ST73405LC hard drive on my W2KServer system won't start. As the boot screen shows devices loading, that drive has a notation "ASYN- Start unit request failed". Device Manager shows all devices and drivers functioning normally, and I can't detect any other system errors. No systems settings or new software or hardware have been installed, the drive just quit loading. Any ideas where to turn for possible resolutions?
