Secondary HDD repeated spin-up/down when going to sleep and shutdown

[frapc]

Hi everyone, I have a dell laptop with primary os SSD (nvme) and secondary data HDD (sata). In the bios, the sata HDD is set as RAID on; the other option is AHCI. nothing changes if the secondary HDD has the paging file enabled or disabled. I clean installed windows 10 when I bought the machine. I am now on 20H2.


I have disabled S0 standby through the platformaoacoverride method found here:

Disable S0 low power idle/S0iX/modern standby/connected standby in Inspiron 5501 BIOS? | DELL Technologies

I recently bought an Inspiron 5501 from Costco. Sleep mode doesn't work out of the box (with S0 low power idle enabled). It is not just my copy of the laptop; the Costco page for the laptop now has...

www.dell.com

the behaviour is the same as before windows 10 2004 (when modern standby was forced enabled).


What happens is that if my HDD is spinning and I put my PC to sleep or I shut it down, it does all its things then the HDD spins down, then it immediately spins up and after 2 or so seconds doing something it spins down again.


It's a complete nonsense. I cannot find ANY way of fixing this behaviour; it looks just like the wrong SATA device management or something like that; all those spin ups and downs are completely useless and definitely unwanted.


I'd be glad if anyone could help me with this.



Have a nice day
