My registry doesn't have a msahci key. Also I went to that website you linked for the drivers before to fix this problem, either the driver wouldn't install or it didn't have any change.
Try to do the same in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor which in my case at least (Win 10 Pro X64) is the entry for the Intel AHCI driver (For lack of better name as it's really just an inf file). Did you install it manually from within the Device Manager as Fernando recommends. Of course back up your registry or take a system image before adding the reg entries
I have a iaStorA, iaStorAV, iaStorDataMgrSvc and a iaStorV in my registry under the path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
Which one should I add the key to?
And I take it you mean for me to add the TreatAsInternalPort key that someone linked a page ago?
Go to Device Manager expand your IDE ATA/ATAPI Controllers entry double click on the SATA AHCI entry go to the Details tab and in the drop down menu under Property choose Service which will show you if it 's iaStoreA or others you mentioned then create the reg entries as suggested in that Article I posted above. Create the Controller0 key by right clicking the iaStoreA or whichever entry was listed in the Service entry as above choose New then Key name it Controllers0 then right click that and repeat to create the Channel0 key then add the Dword in the right pane and restart. If it works then create the other keys to block other drives
Under Service it said storahci, so I did as that link said and there's no change.
I just fixed this ejectable SSD issue and this was the cause for me. This motherboard (Crosshair V Forumla-Z) has 6 "normal" SATA ports (AMD) and 2 other SATA (Asmedia). The Asmedia ones are indistinguishable on the motherboard itself making using them by accident very easy to do, all 8 ports are together in two rows, same color and all that jazz. When I swapped the 840 Pro over to the AMD SATA port, problem solved.
This is my old secondary system I have set up for my wife, I didn't want her ejecting it by accident, kind of curious what would happen though.
