Sounds good (esp. for laptops/notebooks, which should preferably run "on RAM" as long as possible) >But it suffers from the same fate - as soon as the disk receives a new >request, it will spin up again. In case of the SUSE bootscripts (and possibly others), some flush barriers are engaged, then the disk is spun down and immediately after the poweroff happens. >So there is no gain, except that just >parking the head without spinning down the spindle can be performed much >faster. What's the gain in parking the head manually if it's done anyway when the disk spins down (for whatever reason)?
