Also, (I know I'm being so paranoid about this upgrade) the travel of the installed shock mount sled doesn't seem to be right. I can see the primary drive and its connector hitting the display board cable. In fact, the display board cable is slightly twisted to get out of the way of the primary drive's connector.

Also, the new drive seems quite caught up on the 4 power (?) wires from the docking connector. That's hurting the cradle's front-back motion. Then there's a little jumper on the display board with the cradle can touch if it's pushed far enough forward, but I'm not TOO worried about this.

Ok, off to check my cable, I am.
