Clicking from power harness??
 

Recently my computer has been unable to recognize my digi rack 002. Once the rack is turned on, it just continues clicking, the sample rate button does not light up and the mute button is lit red. I heard recently it may be a problem with the power harness, and that digi racks sold around the time I purchased mine(DEC. '03) were shipped out with defective power harnesses. Has anyone else heard this? And does anyone know why a digi rack may be behaving like this?

Go up to the top of this page and click on Search the DUC.
Use "power harness" as the search phrase.
It's been discussed more times than you'll likely want to read about.

Yes, your symptoms are possibly the harness issue.

Good luck.
