I've been on windows 7 since the beginning and although it had and still do have its ups and downs but I think Windows 7 became pretty stable and reliable. Over the years I have also took my time to tweak several of my Windows 7x64 Pro  to its max performance and privacy and I have to say... I love my Windows 7,  its fast and runs glitch free.
 
Time is approaching fast and windows 7 support will end so I'm thinking on upgrading to windows 10 Pro for Workstation, there is a reason I chosen that version but that is separate from why I'm reaching out to you guys as I'm sure a lot of you run Windows 10 so maybe I can get some closure on what I'm dealing with. 
 
ATM. I have several asus x99 WS-10G workstations with ton of internal mechanical HDDs (80TB) but they are set to run only for 10 min. and then to power off and they stay off until they are needed.

Since 3 days I have been  testing windows 10 and everything seem to work fine but I'm having hell of a time with the HDDs, I have them set in Power Option to turn off in 10 min. sometimes it takes 10min and sometimes 20min for them to go off, hey will stay off for 10-15 minutes and then spin  back on and they will spin again for # of min. then go off and then they will be waken by who knows what and go on again. This is driving me nuts. I have looked on the internet and it seem that ton of people have that issue but no one can find solution and this is happening on windows 10.

Before you ask if I have set the power setting correctly or disabled indexing and disk defrag as all these will or might cause HDDs to spin, yes all its turned off I have also turned all background apps from running.
 
This is just an example what I'm referring to, there is ton of people have this problem :

https://www.windows10foru...-down-hard-drive.4881/
 
There are theories that maybe this or that is doing this or that but shortly after that theory becomes the reality again because nothing is fixed.

So..I'm curious if any of you guys have that problem, you would have to have additional mechanical HDDs on that system which some of you might have it,  is this something common with windows 10, what is going on

BTW. I called MS and o boy, how some of these guys get that job, you talking apples they talking bananas I wont even go there I was absolutely disbelieved with such low level of knowledge some of them have.
Any theories  or suggestion would be great. 

 
Moved to General Software.

I wont use win 10 either....my guess would be Telemetry, since that's the main difference between 7 and 10. Nvidia drivers have it too but its seems to be a debate whether its actually being accessed or not. I would say its probably not a bios issue/setting cause its only in win 10 you have this problem, so it has to be a setup in there. If its not a power options setting then maybe its a service that needs to be disabled or a registry tweak.

Thanks guys

I remember reading somewhere that at first launch of windows 10 people had a  big issues with their HDDs being used 100% in task manger,  eventually this was solved, but is it really solved completely. This might be one of the reason why my HDDs are been triggered by something and it's hard to pin point because there is so many system processes running in windows 10.
 
Speaking of Telemetry, you can turn it off but only in win 10 Enterprise but there are way of disabling tracking service that is connected to telemetry service and I even did that but was no difference.
 
Man! MS really want to know every move you're making, this is nuts. I don't even know that I want to switch tbh.I am perfectly happy with Windows 7:(
 

I hope you setup the dual boot on two separate drives. If not this is why you have some issues.
 
Otherwise on the Windows 10 system boot make absolutely sure you have the Windows 10 motherboard drivers (chipset) installed as well as any and all Windows 10 drivers specific to that motherboard from the manufacturer.

 
The first time I was installing Windows 10 I was installing on single SSD and I had that issue so after day or two of playing around with it I reverted to Windows 7.
 
 
The first time I was installing Windows 10 I was installing on single SSD and everything else was disconnected  and I had that issue so after day or two of playing around with it I reverted to Windows 7.
After few days I went back to reinstall Windows 10 hoping to look some more  and find something  I have partitioned my SSD but also disconnected my other drives while I was installing windows 10. 
 
The drivers are pretty much the same for both Win 7 & 10 with small exemption to USB 3, windows 10 comes with its own USB 3 controller  and everything else it's pretty much  the same.
 
I think a lot of ppl using either single drive or let the HDDs spin constantly or they use SSD only but there are some fox out there that use more than one HDD and /or want to turn them off while not in use and know the same issue as I'm describing.
 

Cool GTX
Have you blocked all the MS auto update features ?  (set network as metered connection at a minimum)
 
Do you have TPM (trusted platform module?
 
Are you using Windows Defender ?
 
Your preferred Security Software - is it the cause ?

Nice suggestions.
 
I have disabled all automatic updates
I don't use TPM
I have tried with defender disabled, also with my own antivirus and firewall, it makes no difference
I have disabled pretty much everything I could that runs in the background, in fact I have uninstall all preinstall apps  and left only whats needed for windows to function properly and yet, still HDD's are been triggered.
 
If this is that difficult to have HDDs under control I don't think I want the darn Windows 10. I will try the process monitor see if I can spot anything related.
 
Thank you guys

Def a unusual issue, but it will def be worth hearing if you figure out the problem so make sure you report back if you do. Good luck!

You should just get rid of that dual boot thing and just go with Windows 10.
I switched from windows 7 to windows 10 myself. I wont go back to it. Would be like dumming-down instead of marching forward.
