I would say you have one that falls in the rare category. Between be wife and I, we have diagnosed/replaced about a dozen clutch and or throwout bearings and we can't remember one ever making noise depressed and not released..... But I've learned to never say never so anything is possible.

Just seems to make more sense to me that by applying pressure to a dry/worn bearing would cause it to grind and/or squeal more so than having no pressure on it. Knew I shouldn't have ditched class that day, D'oh!
