That's true but it is more expensive!

Newer hardware that started about 5 years ago or beyond a few years, they
had been making hard drive that will stop spinning disks.  You must setup
the bios in CMOS for that.  If your CMOS has the listing "Power Management"
(NO, NOT WINDOWS) then highlight it then enter you will see "HD POWER DOWN:"
and the ranges will be "NEVER" to "15 min" depending on your CMOS.  Your
hard drive must support it or it will keep spinning.  I had a Seagate 260mb
and it will not power down until I got myself Maxtor 1.6gb a few years ago
and that powers down.  The hard drive will turn on the instant you use it,
just give it about 5 sec for the disk to spin up to speed.

Check out http//www.tomshardware.com

He recently did a hard drive comparison that among other things compares noise levels generated by 
the drives.

Oh, I'm aware of that - but it doesn't work with SCSI disks, AFAIK, as
the BIOS spin down only goes for EIDE drives (correct me if I'm wrong -
at least I've never been able to get SCSI hard drives to spin down that
way). Problem is: The only machines with (E)IDE I have don't have
"green" functions... :-}
So, for me personally the solution will be: Keep old hardware and switch
off when not in use. :-)

Interesting suggestion, thanks! I might just give that a try!

Yes, your SCSI drives won't spin down via BIOS; it seems to be a function of
the OS instead. I've got two SCSI drives on this machine, running Win2K Pro,
and can spin the drives down if I want to, one at the time.

I vaguely recall Adaptec having some kind of SCSI utilities that would work
with their cards, but they were Windows only. No source either.

Sorry, I was thinking of EIDE's.  True BIOS does not have it (at least not
on my machine).
