I'm trying one more time to revive a 320gb Hitachi HD that I believe had flipped PUIS switch by v.9879. At least it shows all the symptoms of it, being revived to work perfectly by booting a Linux disk but then after first shutdown it disappears from BIOS except for a strange line of ------'s.
I tried to reinstall WIndows 10 latest version per the suggestion to cure it, but it doesn't correct the problem.
Having read all of the MS Answers threads above about this disaster, I've tried everything that Windows offers to flip the switch back, however the prescribed bootable hdparm tool doesn't even indicate that the PUIS switch has been flipped so it cannot correct it as others have done.
I am not fluent in Linux but I wonder if others familar with the problem think that the Linux solution offered would work better, and if so I wonder if you could walk me through it. I have GParted booted and am running the Long Test. I now need to run these sudo commands given in MK's Solution given in Build 9879 hard drive disaster (read this) - Microsoft Community:
I have renewed sympathy for those who come to Windows forums and think we're talking another language because I cannot parse the Linux-speak here and can use some step-by-step guidance. I have Gparted now running Full Test.
Hi all,
I've pinpointed the issue which is related to this function of HDDs http://en.m.wikipedia.org/wiki/Power-up_in_standby
Your motherboard doesn't support PM2 and neither does mine.
You should get your old HDD back as it is OK. Windows haven't broke the hardware.
Guys in your shop are lame, sorry.
That's the explanation of what's happening:
HDD gets power (electric current) but stays still instead of spinning (it waits for ATA signal).
If your BIOS doesn't support it (you probably get something like "SATA1 0MB") bootloader can't start so Windows won't work.
On the other hand, Linux supports direct communication with SATA drives so here comes our saviour.
SOLUTION!
a) One time
You can fix it for one time by booting Linux LiveCD/LiveUSB and rebooting - Linux communicates with SATA drives and spins them - after reboot BIOS will detect your WD drive and so will Windows.
b) Permanent
(that is until Windows 10 overwrites the setting again)
Follow the instruction and avoid Sleep on 9879.
After you boot your LiveUSB/CD:
1. Open Terminal (Ctrl+Alt+T or Ctrl+Alt+F1 or just click the icon)
2. Execute:
sudo hdparm -iI /dev/sd?
sudo hdparm -s0 /dev/sd?
hdparm is a Linux tool for configuring HDDs.
First command displays some info (look for Power-up in Standby on the list - Shift+PgUp to scroll the output).
Second commands sends disable command to that feature.
'?' in commands should work as a wildcard but if it doesn't use 'ls /dev/sd*' to find the letter of the HDD (it usually is either /dev/sda or /dev/sdb - but sometimes can even happen to be /dev/hda)
Credits go to T61T9300 - I couldn't find that command
Here comes the explanation of what happens in there from the author of HDAT2 http://www.hdat2.com/hdat2_faq.html#q19
I'm happy to make your 'bricked' HDDs working fine again.
Thanks for any help to save my two drives that will not repair with the Windows fixes given in this or either of the two MS Community/Answers threads quoted.
