Terry,

I would start by carefully checking all the internal cabling for partially-seated connectors and/or tarnished contacts. Reseat all the chips on the controller board with a push of the thumb, etc. If your unit has the piggyback Z8 (EPROM on top), pay special attention to that socket. Power supplies on these things are not the world's best, so worth checking voltages also.

I think I know that little brrrpping sound you describe, but I'm not entirely sure what causes it.

At least one drive here had a fading Hall sensor on the HDA. I moved it in a bit closer to the metal finger on the flywheel and brought it back that way. Symptom there was the drive not reliably coming ready after spin-up.

Steve
