	Under NetBSD, OpenBSD, and linux, there's a utility to put the hard drive
to sleep after a certain amount of time (atactl for the first two and hdparm for
the third). I've looked around through mailing list archives, and through a running
system, to try to figure out how to power down the hard drive (it's an APM 1.2 
compliant BIOS, thinkpad i\1460) under freebsd, but I can't find a good way.

	Is this possible? Are there significant hard drive power gains if it's spun
down in a laptop?

Thanks,
Derek Moeller
