Hmmm, it sounds like that drive might be bad.  You should be able to probe the bus while that drive is installed; it shouldn't break anything.  I would swap it with another from the seller, if possible.

My experience with the drives that won't spin up is that they don't interfere with the bus, and they still return inquiry data.  So you should certainly be able to see everything from OBP on a Sun, even if the OS can't spin it up.
