Well, I see from your tagline that you just added a drive to your Empeg... The first thing I'd look for is a loose master/slave jumper. I had that problem, and had to electric-tape mine in there to keep it on. If the jumper slides off, your Empeg won't boot. There are a hundred other things that could be wrong, but that was the nature of my problem before. I agree, it's a horrible feeling when it doesn't boot up!
