Windows 10: SATA HDD & SSD shown as removable

Bios does not have Hot Swap options for SATA drives.
Interface is AHCI.
Have tried: " reg.exe add “HKLM\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device” /f /v TreatAsInternalPort /t REG_MULTI_SZ /d x"
Which corrects for one drive but when run on the second drive the first drive reverts to removable.
I doubt very much that this is a driver issue; it's just a typical Windows SNAFU.

Weird file path bug?

Hi!

There is issues with HDD and SSD on the same motherboard if the motherboard does not support it. Is you SSD plugged into a SATA port or PCIe port/slot? You may have to put the SATA into IDE mode. You could look up the motherboard at manufactures website
and see if they have a manual.

Google search

HDD and SSD on same motherboard

 

Why is there no AHCI mode in my BIOS??

Yes, you do need to set SATA mode to AHCI for your SSD wo work correctly

AHCi is not a boot mode or priority, you seem to be in the wrong BIOS Tab

Look on the system Status or Advanced settings sections

Look for SATA MODE setting, then set that to AHCI

Please note the following is the procedure for installing Windows 10 on a system with an SSD for OS and Apps with a HDD for Data:

1. Remove the HDD

2. Plug the SSD into the SATA Port the HDD was pluggedinto

3. Set SATA mode to AHCI (must be done before installing Windows)

4. Install Windows onto the SSD

5. When Windows has installed completely, turn off PC

and reconnect the Data HDD to another SATA Port

 

Actually I have seen this caused by older versions of the Nvidia Drivers , but can't remember the Series number , but try 382.05 if you Card can use it? pretty fast and stable and no issues like the 388.x Series here.

I had the same problem but only had one drive. I found this in another forum and decided to save it.

If Kbird's solution does not work try navigating to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\storahci\Parameters\Device in the registry. Once you are on the Device Key, In the right hand plane, right click and create a new Multi-String Value Name the new value TreatAsInternalPort Double click the new value to edit it. In the Value Data section, start with 0 then 1 2 3 depending on how many ports you have. The trick here is they must be numbered vertically. The value data section will look like this:

0
1
2
3

The example will work for four ports.

I have not tried this myself but the person who posted it said it worked.

 

Fantastic. Worked a treat. Thank you.

Now I just have to sort out the Marvell 91xx controller.


Update: I add the Bus No for the Marvell 91xx to the list and that solved that problem too.
Bonus points to TrustMe. *Thumbs

 

Thanks for the update.

 

Hairy Scot:
I'm having a little difficulty visualizing what the resulting registry structures look like here. Could you please post a screenshot of the final values as you set them up for that TreatAsInternalPort entry? TIA for the extra effort.

The Marvell Controller was shown as removable too ? I didn't see that on my X58A Board , not sure what Driver I am running though for that, I'd have to check...

 

That's usually fixed by using the correct Marvel Driver, not the generic thing that Windows seems to like installing.

See this post Marvell 91xx Config Missing Driver - Windows 10 Forums It's what I used to fix both the Drive and the Controller being removable.

 

Thanks Clam it is slightly newer than the one I have , here is the direct link to the webpage with the File
