I disconnected the 320GB HD, re-booted, changed USB cables, changed USB ports, zapped PRAM, tried Disk Utility, Drive Genius, and TechTool Pro. None of them recognized the HD. I'm out of ideas. I'm afraid I have a bad HD -- all of which happened when the power unit broke. IOmega replaced the power unit, but still the HD is not recognized. Any other ideas?
