I was wandering when someone will suggest this, because this should be the first answer.
I'm 90% sure that problem is in wrong jumper setting or in bad IDE cable... I've seen it too many times. It's hardly to believe that drive "just died", especially on piece of hardware that has no electronic elements exposed to static electricity, scratches or something else (in opposite to HDD, for example).
Ofcourse, I could be wrong...
