    Change internal SATA disk from removeable to fixed in Windows 10

    I just spent a long time trying to find the best answer for this and wanted to save people some time... this is specifically for Windows 10.
    (So, the answer is basically here:

    Add a new "Multi String Value" called "TreatAsInternalPort" to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device with the values "0|1|2|3|4|5|" (the | symbolizes a new line)
    (I had to reboot two (2) times before the changes took.)

    I had to do this fix because BitLocker has different options specifically for fixed, local, internal drives as opposed to a USB drive or eSATA drive which is removable. Also, this gets rid of the "Eject" option in Windows 10 for mislabeled internal HDDs.

    This is what it looks like when storing the values into "TreatAsInternalPort":

    Well, I just installed the Intel Rapid Storage Technology drivers and all the corrected fixed drives that were once removable changed back to removable. I also installed the latest Intel Chipset Software and Marvell SATA Controller drivers. And I'm not completely sure which driver update switched them back to removable. So, I recommend installing the drivers first before doing the fix above to the registry. I am going to attempt to do the fix again and if I have problems I'll write back here otherwise consider it done.
