    Non RAID disks show as removable but RAID disks show as normal


    Hi everyone!
    I researched a lot over this problem, but I cannot figure out how to resolve it.

    Motherboard: Intel DP55WB, BIOS version: 0336
    BIOS has 3 options for hard drives: IDE, RAID, AHCI

    In Windows 10 Pro x64
    If I select AHCI in BIOS all disks show as internals, but cannot work with RAID.
    If I select RAID in BIOS all RAID disks show as internals, and non RAID disks show as removable.
    IRST (Intel Rapid Storage Technology) version: 16.7.0.1009, for Windows 10
    1 x SSD Kingston HyperX Savage, as stand-alone, shown as removable.
    2 x Toshiba (mechanical) SATA3, as RAID 1, shown as internal.

    In Windows 7 Ultimate x64
    If I select RAID in BIOS all RAID disks show as internals, and non RAID disks show as internals too.
    IRST (Intel Rapid Storage Technology) version: 12.9.0.1001, for Windows 7
    This configuration works flawless.

    Any advice?
    Thanks in advance!

    This behavior depends completely on sata/raid controller driver used. For standard intel/ms drivers, you can try this:

    - in device manager determine the name of driver service (for example storahci, see the picture)
    - if necessary change the service name in the following reg file
    - import reg file & restart.

    Code:
    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device]
    "TreatAsInternalPort"=hex(7):30,00,00,00,31,00,00,00,32,00,00,00,33,00,00,00,\
      34,00,00,00,35,00,00,00,36,00,00,00,37,00,00,00,00,00

    Or you can check which driver is used in win7 and install/select the same (it may be win7) or similar, but this experimenting is dangerous; before doing this, it is necessary to make system image using macrium - system can crash after disk controller driver change.

    Thanks muchomurka!
    I've already tried that solution with no luck...
    I think Windows 10 is not recognizing very well BIOS settings.
    As I said, when BIOS is set as AHCI there is no problem at all, but when it is set to RAID then the stand-alone disk is shown as removable.
    Strange behaviour...

    Windows 10 x64 includes IRST version 15.x.
    After reinstalling I just run IRST version 12.9, wich it works fine under Windows 7 x64.
    Then problem has gone!
    Thanks!
