I have 30 gb which exhibited the same problem. I had replaced the drive IDE cable for this one as well. It worked well for a few days in my car. Then I sometimes got the clicking, would take out of sled and put back in, and then it would boot. Got to a point where it would not boot anymore in the car. I swaped my home 10gb with my car 30gb empeg. Tried several times and eventually the 30gb booted at home and has been working since. I'm afraid to put the 30gb back in the car. Is this a sign that my 30gb drive is about to die? The unit is only a few weeks old.
