Agreed - I don't think hdparm should be used outside of a 'last resort'
situation where the kernel gets it wrong.  This is happening less and
less over time, but it is still occasionally necessary, so I keep
maintaining it.

I don't want to automatically do anything by default - I'm just looking
to redo what the admin asked for so that settings get reapplied if
they've been lost over suspend to disk/ram.

Cheers, and thanks for the pointers.
