I have added a large drive to my desktop for back up purposes. I am
using rsnapshot to backup just a couple of times a week. Since the

/dev/sdb {
spindown_time = 180
}
To hdparm.conf to spin down the disk after 15 minutes of inactivity to
save power (yea goin' green!)
Everything is working right except when I go to restart or shut down the
pc. When I do that, right before init runs halt the hard drive spins up
and then the pc shuts off. Does the hard drive have to spin up in order
to flush a buffer or something before shut down? Any way to get around
this? The sudden spin up and then shut off doesn't seem like it would
be good for the disk, makes alot of noise when it does it too.
Is this just "normal" or what?
Yes. The drive must spin up before being dismounted.
I suggest that you only mount the drive when needed. Besides the
safety of preventing you from accidentally deleting needed files, it
boosts the likelihood that the kernel won't need to spin it up
during shutdown.
