Hard drive power saving

Does Windows XP SP2 support hard drive power saving on hardware level or by
partition level? I want to know that if I have a hd in a computer without
any partitions that Windows recognizes, will Windows spin it down according
to the power saving settings?

How do you expect this to function?

Can you imagine only 1/3 of your hard disk rotating?

Power saving applies to a physical device [an entire hard drive] and not a
portion of it.

Unlike a motor vehicle engine, where fuel savings are managed by shutting
off fuel flow to one or more cylinders, one cannot cut of the energy to a
logial partition.

But that is not what he asked. He asked if he had another hard drive in
the computer that had partitions that XP did not recognise would that
specific hard drive spin down. He is not asking about a seperate
partitions on the XP drive.

If you have a hard drive without a partition, you'll know it. (kidding)
The power options should support spin down of multiple drives in the pc.
Although, if there is a hard drive w\o a partition, i doubt it will be
spinning anyway. If i'm correct, the extra drive won't spin until it
is partitioned and in use.

no....it treats power saving to the hard drive device, not to individual
partitions. Because the computer system supplies power to the hard drive
(as a whole) not to individual partitions

How will the system know whether or not there are partitions until it
spins up the drive and checks? -- Once the drive is running (And most
spin up on power-on anyway), it will stay running until something turns
it off.

Settings Windows to shut down inactive drives will spin down drives
without partitions -- I tested to confirm :)

For one, i hope you don't run too many tests. For two i never said it
didn't spin up for a check on boot. YOU assumed i did. for three, even
when a partitioned drive wont spin up, a major factor is a partition
problem. Look it up. for four, i just checked my non p samsung in my
athlon and guess what braniac, it didn't stay SPUN. So before you think
you know what you're saying, and trying to make others look like fools,
read your Q&A and apply it to yourself. :)

Thank you very much, you saved me that valuable testing time.

All drives are spun up at boot time - the BIOS does this and has nothing
to do with Windows. Unless you have a SCSI setup you can't alter spin-up
parameters on standats IDE disks.

All drives (partitioned or not) will stay running in Windows unless the
whole system goes into suspend or hibernate mode - you can't select
individual drives in the power options.

Some systems additionally have a BIOS settings that allows disks to turn
of after a period of inactivity - again this has nothing to do with
partitions.

On an individual drive basis, no. However, you can set Windows to "Turn
off hard disks" after a period of time.

This will affect all disks on the system. If you set it to 15 minutes,
then any drive which is idle for 15 minutes will be shut down.

Since a drive without any partitions will be idle virtually all the time
(unless you're running some disk tools that are accessing the drive)

Where did you learn to read? yikes! no one said about altering
parameters, simply that windows will shut down disks in power options.
And NO not in all systems will the hard drive stay spinning if there is
no partition.I have one to prove it. Did i say you can select individual
drives???I said M-U-L-T-I-P-L-E .
And yes, partitions do have to do with some hds not spinning up. Search
the net, look through windows newsgroups, read a book, you will find it.
A couple of points are arguable but you didn't make any on what i wrote.
GEEEEZ.

I dont think I have tested this - and its probably not 100% predictable.

e.g. If a second unpartitioned drive is inactive in itself but there is
a slave device on the IDE channel (e.g. CD) then its controller runs the
secondary drive so will it spin up on a CD access? You'd have to test to
be sure.

Also the SMART power down settings interact with windows settings on
some setups so Im not sure things are as simple as they appear.

I take your point about the power down settings - though this will
indeed shutdown all your inactive drives, ever the Windows drive if you
are idle for a while, which you may not want. Selecting an individual
drive would be ideal - this may be possible in the SMART settings on the
drive - again its something you'd need to test.

In previous years it was advised not to use HDD power down settings on a
desktop as it can wear the head load mechanism - but I think that isnt
relevant now.

Power down modes on hard disk are related to drive access time-outs when
the system sends a specific sleep mode command. It has *nothing* to do
with partitions. If you have some fantasy information from comics or
pizza boxes then quote it here.

Just think about your home made ideas before posting - how could the
system tell if any disk had a partition without actually spinning it up?
Maybe it has a note on a bit of paper somewhere? doh!

You dont have a system that doesn't spin drives up - all non SCSI PCs
spin all drives up unless you have manually disabled the drive and the
BIOS immediately supplies a sleep mode command. What is the
PC/drive/BIOS you are using?

Once again, another person who can't read! This is amazing! As I said
at the top, All hard drives spin up at start, if no partition is found
it will NOT stay spinning when there is nothing to read! Who are YOU to
tell me about home made ideas when you don't even know that a non
partition hard drive will not stay spinning? I will post my fantasies
when you learn how to read them!

Read your posts:

*"Although, if there is a hard drive w\o a partition, i doubt it will be
spinning anyway. If i'm correct, the extra drive won't spin until it
is partitioned and in use."* (thi is incorrect - also called 'wrong')

and you also said

*"And yes, partitions do have to do with some hds not spinning up."*
(also wrong)

but you just said

*"As I said at the top, All hard drives spin up at start"* - umm, where
is that bit exactly?


I've never seen someone actually decide to change what they said in a
newsgroup - hint: its printed for everyone to read.


Please post any references you have re. partitions and disk entering
idle mode, as you say:

*"And yes, partitions do have to do with some hds not spinning up.
Searchthe net, look through windows newsgroups, read a book, you will
find it."*

Post these references, as you have many I'm sure. Go ahead, don't wait.
Please do. We are all in a rush, as are you.

I meant the top of the first page, when i stated...(For two i never said
it didn't spin up for a check on boot. YOU assumed i did.) So once
again, go ahead and make yourself feel better thinking you have some
godly knowlege. Just because someone is a smart @$$, doesn't mean they
have a brain. I emailed maxtor and western digital, I was told that in
some systems the disk will not spin after no partition is found. Just
like any posting site, even if someone is wrong there is always someone
to try and step on them but luckily (i don't care) i think it's funny.
There are many technicians that are wrong every day. Well gotta go, I
have to watch the next episode of AUS Almighty!

Sorry, PCDaddy, but most of us here aren't psychic (or pyscho) so we can
only go by what you actually said, and often not much divining effort is
employed in figuring out what unmentioned information you may assume in
your statements that you don't tell us. There is what you said and what
you meant to say.

What you said: "if there is a hard drive w\o a partition, i doubt it
will be
spinning anyway."
What you meant to say: "if there is a hard drive w\o a partition, i
doubt it will REMAIN
spinning"
Whether the drive remains spinning depends on the power options. I
don't recall the BIOS power saving options or those in Windows where you
can differentiate between drives, so you apply the same power saving
options to all drives.

What you said: "the extra drive won't spin until it is partitioned and
in use."
What you meant to say: "the extra drive won't REMAIN spinNING UNLESS it
is partitioned and in use.

So, with the guessed assumptions of what you meant to include in your
statements, sure, you're correct in what you meant to say. I drew the
same conclusion as DevilsPGD regarding your statements. Maybe you were
correct. DevilsPGD is correct. So it sounds like you simply corrected
your post by claiming everyone should know what you meant to say.

Did you test with the hard drives on different controllers, or were both
drives on the same controller? For IDE, both the master and slave drive
on the same port are using the same controller. If the master is busy
but the slave is idle, does the slave actually power down? When looking
at the signal pinout for an IDE cable, like at
http://www.bbdsoft.com/ide.html, none of the signals have to do with
power, so it must be an instruction sent to the hard drive to ask it to
power down after some period of idleness, so I continued my Googling to
find out how to stop/start the platters spinning.

From what I found, an instruction code of E0 (hex) spins down the drive
and E1 spins it back up; see
http://hem.passagen.se/communication/ide.html. So it looks like the
drives can be individually spun down based on a separate expiration
timer for each hard drive. What I'm wondering is if the spun-down
*slave* drive will remain spun down while the shared address and data
bus are active for the *master* drive. After all, how would the slave
know that an E1 instruction was sent to it for it to spin back up if it
wasn't actually powered up to read that instruction? The platters are
stopped from spinning but the hard drive doesn't actually power down
since the logic on the PCB still has to be alive to know when it gets an
E1 instruction. So it definitely looks like you select individual
drives as to which ones are spun-down to save the power consumed by the
motor.

Well good for you. you added two words to my reply that you figured
should have been the way you and devilspp would like it. Oh so now i'm
psyco for defending myself. If you would have read every post clearly,
you would have seen how my words were completely twisted on most, not
just someone mistaking what i meant. for one, all you did was stick up
for devilspp and made no real point. for two, i don't see how many of
the replies to my reply were that badly assumed. And all you did was
defend someone and jump on the good guy bandwagon. Are you looking in
the mirror and smiling at yourself now? Proud of yourself? instead of a
later post that means nothing, go help someone if your so smart.
