Have you tried to start the computer in safe mode. Or will it not start at all. When you say "died" do you mean it does not work at all, meaning just nothing happens. If that is the case you could first check the power connections on the back of the drive to make sure they are fastened well.
If you can get it going and can get onto the internet try for a firmware update to see if it helps you. Sorry thats all I can say.
