Hello!
I´m using a ASUS Sabertooth Z87 after updating to Windows 10 (clean install) everything was working ok.
My normal HDDs went to sleep after the set amount of time under energy settings then I installed some Intel driver (LAN,chipset,IMEI,IRST).
It seems that the SATA AHCI controller driver installed by IRST doesn´t allow HDD sleep anymore.
The only way to get it working again is using the Win10 stock SATA driver and removing IRST.
Is there a working driver, a workaround for this problem or do I have to wait for Intel fixing that problem.
with best regards,
Chris
