I just purchased a new Mac Pro and received it yesterday. The tower came with a 500gb drive built into bay 1. I have a Seagate Barracuda and a Western Digital WD3000 which are at 300gb each. When attempting to install into bays 2 and 3, the computer does not boot. My cooling fans and the GPU fan just spin at an insanely high speed making nothing but noise that gives me a headache. The monitor doesn't show anything either, doesn't even turn on. The drives fit flush and the door can lock. I did remove the drives and I noticed that both of them had bent pins after installing into the computer, these werent like that before. I straightened out the pins and I still can't get the computer to start. I can't afford to format these drives either because I have important data on them which I can't afford to lose. Anyone have a solution? Thanks.
