I run a Samsung 970 Pro in the second M.2 slot. I am trying to run a Samsung 860 Pro 1TB on a SATA port. It seems quite often the Intel Rapid Storage "Removes" the 2.5 inch SSD and I get a message regarding the situation.
It seems to work OK some of the time but disconnects far too often for the situation to be acceptable. I ran an 850 Pro on the same SATA connector and it was never disconnected. I read the Samsung Magician software may be at fault so I uninstalled it without any noticeable change.
I have the M.2 slot set to x4 and I am not using the first M.2 slot so the SATA ports I am using should not be effected by the M.2 slots.
The Event Viewer is showing an EventID 129 iaStorAC "Reset to device, \Device\RaidPort0, was issued". Link State Power Management is set to OFF in Windows but I need to check what the Bios shows. Once the drive has been disconnected, it seems to stay that way, even during reboots.
As far as I know, the Bios and all drivers are up to date and this happened prior to Bios 1602 and continues with it.
Thanks for reading...
