CDC Wren III hard drive parking mechanism

[Alex Nghiem]

We have a CDC Wren III that just crashed. Our tests indicate boot
sector 0 is bad. However, upon closer observation we note that
the clicks that normally occur when the auto head park mechanism
disengages upon power-up is not there any more, leading us to
speculate that maybe the head is stuck in the park position.
Is this a common occurence with CDC Wren drives? Is there a 
simple fix?
