     I think that the main purpose of the shock detection system is  
to allow data to be recovered from the disk in case the laptop is  
broken. By parking the heads asap you can avoid damaging the plates  
with the head.

     At least that's what I read. The disk won't be necessary usable  
after being dropped, but at least the plates should be readable.

     In that case, priority number one would be a fast parking of the  
head. However, it could lead to a worst-case data loss with  
softupdates and the disk cache, isn't it?
