Vista Ultimate x64 is stopping hard disks after sleeping, even when told not to.

Hi. I have encountered a problem with hard drives shutting down after the
computer is woken from the sleep state.

Im running Vista Ultimate x64 on an Asus P5B Deluxe motherboard, and have 3
hard drives connected.

On the initital cold boot, the hard drives respect the Power Options
settings which tell them never to shut down. If i then manually(its set
never to sleep automatically) ask the computer to sleep from the start menu,
it does so without issue. It awakes as expected. I have turned off hybrid
Sleep as it is significantly slower than S3 sleep and i have a UPS anyway, a
Belkin model that has recent software support for vista.

However, after the computer being woken the hard disks are then instantly
shutting own when idle, no matter what the Power Options are set to. They
even shut down before it reaches the desktop on wake up. If you try to
access them there is a pause and you can hear them spin up. If you wait even
15 seconds and try to access somthing else it can be heard waking up again.
When you ask the computer to shut down fully, the drives go to sleep before
it finishes shutting off and have to be woken up again before the final shut
down occurs. On another clean reboot/cold boot they then respect the power
options and stay on permanently. Send it to sleep and wake it up, they just
ignore the options and go straight to sleep.

Standby works fine in XP in the same computer.

I tried searching google, the microsoft forums etc with litle luck. I found
one person who reported the same issue on the microsoft forums last
september but nothing other than that.
Any ideas ?

Thanks,
Robbie

No they are on the sata ports on the mobo from the Intel ICH8 southridge,
and the only sleep related options in the bios control what state it enters
(ie S3).

Its truly oddball. Its fine on first boot, it sleeps fine, but once rewoken
the hard drives wont stay awake despite the options telling them never to
sleep.

Yeah it effectively does treat the UPS as if its just a battery in a laptop,
but ive got all the power profiles set, even the options for battery power,
and windows power meter states its 'plugged in' anyway.

I dont have mobility center as its not a laptop, but from the screenshots
ive looked at, all it lets you do is choose the power mode you are running
in, which you can obviously do through the power control panel or using the
power meter try icon.

All in all its a weird problem, if an update fixes it yippeee, but other
than that im just gonna put up with it for now and not use the sleep
function as its not worth my time pulling the computer to bits for...next
time i happen to be pulling it to bits for another reason though i might
investigate
