Okay, no dice.  

I also tried attaching just the power cord to the HD, -removing the SCSI cable.  It does the same thing -powers up the HD at startup then spins back down.

I've cleaned the MB really well, and the Analog board.

It's going to take me a bit of time to make a bootable disk from my PC that will work on the MAC w/ Lido on it. (need to read up on how to do that). (I have a USB floppy drive).

any other suggestions before I continue down the path of the boot drive/lido?  Is there any hardware component that would cause this spin up then down?
