I know Windows can spin down your hard drives if the system has been inactive for certain amount of time, but can it do this on a drive by drive basis?

I've got a file server which has about 8 drives in it. I want to set it up so that a particular drive will only spin up if someone tries to access it.

As it's a fileserver I'm not too fussed what I install, will consider anything.

I do exactly this using Ubuntu. Simply type into the terminal

sudo hdparm -S60 /dev/sda

and it will set your first hard drive to power down after 5 minutes (S60 x 5 seconds = 600s + 5 minutes), you can then do the same for /dev/sdb /dev/sdc ect.
You can also put a drive to sleep on command with

sudo hdparm -y /dev/sda

I run this plus a few other commands at start up in a little script, it all seems quite daunting at first but once you get your head round a few things it's much simpler and more logical then trying to find the right option in the right menu of windows. Ubuntu forums is a great place to find the answers to any other questions and

man hdparm

is the manual for the hdparm command.

Ubuntu or one of its variants is definitely the way forward in this respect.
