I have only just attached some hard drives to the 6G SATA ports of my motherboard and those drives are showing as ejectable in Windows 10.

When I first installed Win10 afresh on my new SSD the drives attached to the normal SATA ports where also showing up as ejectable. However after I installed the Intel Rapid Storage application they disappeared from the list.

There are no Win10 drivers for the Marvell and so I just set the compatability to Win7 and installed them from the ASUS setup utility.

I did find a GUID for the registry that should have provided a policy page that should have at least managed to hide the drives from the safely remove hardware feature, but it doesn't do anything on Windows 10.

Any ideas?
