I believe that 'emergency' spindown (on power fail) is different from
regular spindown, and that emergency spindown damages the disk more.

But perhaps park + power fail is similar to regular spindown?

(Is park command normally supported on modern disks? IIRC hdaps people
had issues with not all disks supporting it?)
