man hdparm
you are looking for the parameters -S, -y and -Y

- y makes it spin down immediately, and -S1 makes it spin down after
there is no disc activity for 5 seconds. That works really well,
thanks a lot.

Wouldn't keeping the drive on at all times also decrease its lifetime?

Along these same lines, is there a way to "wake" a drive from a
standby or sleep status? For example, say I know that I will need to
access a second hard drive in a little bit, could I issue a command to
wake the drive before I need it, so that there would be no waiting
when I actually need to use the drive?

No. Shutting it down and having spin up over-and-over again
will increase the tear and wear of the drive mechanics and
decrease the lifetime - unless we're talking about notebook
drives, which are made for this.

Ah, mine is a notebook drive. You think the spin-up-spin-down won't
be so hard on it?

In this case - (uhm, what's the correct answer?) no/yes, I do/don't
think so :)

IOW: For notebook drives, shutting it down should be better than
having it run all the time.

At least he's honest! :) But you do know that spinning up and down is
generally easier on notebook drives?

No. I seem to remember some tests by some computer magazines, but
don't know for a hard fact.

I think spinning up and down may be easier on notebook drives. But I
guess the major reason to do so is to save power, rather than increase
its lifetime.
