Windows 10: Internal SATA drives show as removable

I put 0\01 in and my C: and D: still show as removable.

 

Install this driver (assuming you have a 64 bit OS):




Don't be thrown off by the RAID label, or the floppy disk thing. The SATA RAID driver will install the AHCI capabilities you are looking for. It will not create a RAID array automatically or anything like that.
You have an old motherboard and Asrock has not updated their drivers since W7. But the W7 driver *should* still work for W10.

 

Drivers mentioned above are for blue SATA ports, not for white ones. Don't use them.

White ports are connected to Marvell SATA controller. Which driver do you use for it, Marvell SATA or Standard SATA AHCI driver? If Marvell one, replace with the second one and restart.

In regedit, check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\Enum - is there value of ypur Marvell controller? (PCI\VEN_1B4B.....) If not, you have to find where it is.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device (or similar). If TreatAsInternalPort multistring does not exist, create it manually. Fill it with numbers 0-7, each one at separate row.

Restart.

 

Found it at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mvs91xx\Parameters\Device

Added the value TreatAsInternalPort
Tried 0 and 1 each on a separate line. Does not work. Regedit deletes all but line 1 and both drives still show as removable. Next I tried 0\01 and that also doesn't work, but Regedit does not delete any of it. 0\1 is rejected by Regedit as an "empty string".

Looks like the Marvell driver is expecting to be told a different way.

 

This may be onto something. Get the Policies tab to appear on the Properties for the Marvell controller.
FIX: AHCI/SATA drives showing in "Safely Remove Hardware" - Page 5

Tried that, doesn't work, but it's not specific to Windows 10. (Also repeats of the TreatAsInternalPort things that's not working.)

It's using the driver provided by Microsoft, according to the Details button.

More info on the policies, that also didn't work to fix this Driver "Policies" Tab not showing in Windows - Super User

 

Marvell driver mvs91xx (including one provided by MS) does not accept TreatAsInternalPort switch. Create restore point, then replace Marvell with Standard SATA AHCI driver which is part of Windows (use Update Driver button). Then insert all the eight numbers, not only two, into the right value in registry and restart.

That's all from me, because you don't follow recommendations, although they are tested on other computer with Marvell controller and AHCI driver - see the picture.

 

For whatever it's worth try the following and hope it helps
go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e97b-e325-11ce-bfc1-08002be10318} When you find this you'll have some folders for that reg key look for the one with Marvell all over it then make a new string value and name that DriverPolicySet and set the value as 1, then make 1 more new multi string value and name that IncludeInfs with a value of: machine.ini

 

Already tried that Driver "Policies" Tab not showing in Windows - Super User Didn't work.

Edit: It's in 0005, not 0001. Finally, it's fixed.

Edit 2: After a clean install, it's in 0000. Consistency, Windows doesn't have it.
