how to disable "Power-up in Standby Feature Set" (unwanted I her enable) on drive WDC3200KS 320GB Caviar SE16 SATA, iv got have motherboard MSI 875P Neo-FIS2R , drive don't spinup & not accesible.


i need software utils to spinup drive in dos of how disable this feature?

Hi,

using SET FEATURES command with these register definition:

06h Enable/disable Power-Up In Standby feature set.

Subcommand code 06h enables the Power-Up In Standby feature set. When this feature set is enabled, the
device shall power-up into Standby mode, i.e., the device shall be ready to receive commands but shall not
spinup. Having been enabled, this feature shall remain enabled through power-down, hardware
reset and software rest.

07h Power-Up In Standby feature set device spin-up.

Subcommand code 07h shall cause a device that has powered-up into Standby to go to the Active state

86h Disable Power-Up In Standby feature set.

With HDAT2 you can in Command/Feature sets menu call Enable/disable Power-Up In Standby feature set, not the second one 07h Power-Up In Standby feature set device spin-up.

Try to disable Power-Up In Standby feature set, because the device requires the SET FEATURES subcommand to spin-up after
power-up if the Power-Up In Standby feature set is enabled.

Same problem here!

I have enabled the "Power-Up In Standby" feature on two hard disks, they have worked fine, and on the next day - they just don't spin-up - and thus can't be accessible at all, laptop BIOS says hdd parameters error and PC BIOS just can't detect the drive.

So my question is the same as martintl's. How to spin-up the drive and how to disable the "Power-Up In Standby" feature. There was no warning in HDAT2 application that this could be dangerous at all! :/ I don't want to lose my information - it is important to me.

Any help is welcome!

So far I have found this:

The whole thing is kind of amazing: toggling the "power up in standby"
feature caused the BIOS of *three* desktop computers to pronounce the
drive dead, and to freeze when booting. In order to get past the
BIOS, I had to hotplug the drive at the GRUB boot menu. And the
default 2.6.20 Linux kernel of Ubuntu failed to spin the drive up as
well. Probably the Linux kernel doesn't support this since it expects
the BIOS to have spun the drive up already.

So I still have some questions...
* does anyone know of a BIOS that actually *does* know how to spin up
drives that boot in standby?
* why isn't this feature marked as DANGEROUS in the hdparm
manual (neither the HDAT2 one) ?
* is there a way to issue raw commands to a drive from Linux (maybe
via /sys) without recompiling the kernel?

Hi,

check your PM please.

hi! i have a problem, the disk can't be detected, so i can't run the ATA command you suggested. here is the log file:

The contents of the IDENTIFY DEVICE data is incomplete.
ATA Error 00h: No error

I have found a solution!!!

Find HDPARM project site at SourceForce. There is an ISO/floppy image available named turn_off_poweron_in_standby. Boot from it and it will detect any hard disk drives with activated PowerUp on Standby feature and will turn it off. Then RESET (do not power off the PC) and run HDAT2 to check the disk.

Thank you !!!

ok, i made the same mistake enableing Power-Up In Standby feature set on a western digital sata hdd. i have a silicon image 2 port sata controller whitch is unable to send the spinup command.

the realy ugly thing is that as soon as i enabled the Power-Up In Standby feature in HDAT2, the setting disapeared from the feature set list.

i rebooted, started hdat2 again, and still, the option is not there anymore.

at the next power cycle i got the drive to spin by booting Kubuntu Live Cd and using the reset button on my pc i managed tu boot the hdat2 cd.

i activated the option with hdat2 ver 4.52 and tried to disable it also with 4.53. No succes... the option simply is not there anymore.

Please document this problem in your next release.

i am now trying HDPARM. hope it does not mess things up any further...

HDPARM can't do shit i found more details about this problem on

h t t p : / / websupport,wdc,com/forum/topic.asp?TOPIC_ID=5063&SearchTerms=hdat2

(please manualy correct the link above, i am not allowed to post it)


It describes the problem but brings no solution.

So, dear HDAT2 creator can you help me? is there no way to force this option off ??? somebody? anybody ?

i would realy apreciate it!

looking forward for a reply. 10x

Hi,

I have read all about it and (I think) it seems that it is a bug in firmware.
With another hard drive if you have enabled this feature you are able to disable it again.

The only possibly way is to claim this hard drive

Problem with this feature is already described in coming version.

I have found that these WD drives have another firmware bug also (report from WD):

"The temperatures reported by all SMART monitoring software is incorrect for the WD2500KS due to a firmware bug.
The drive is not defective but the temperatures that the revision of the drive you have bought report to software are incorrect.
We are working on a solution."
