u can fix this inside windows
first make sure that write caching is enabled
u can find that in control panel -> device manager -> disk drivers -> your drive - options
Under Policies tab, make sure "write caching on the device" is enabled, there is no "optimize for quick removal" enabled. This is directly related with how Windows considers a drive being removable.

if this wont apply for you, u can try in registry

Step 1. Right-click the Start button in Windows 10. On the Power Users menu, choose Command Prompt (Admin) to open a command prompt with administrator privileges.
Step 2. In the command prompt window, type the following command in hit Enter: devmgmt.msc
Step 3. Under Disk Drives, identify the SATA device you would like the inbox driver to consider internal and open properties for this device by right-clicking and selecting Properties.
Step 4. Note the bus number from the properties overview.
Type the following command in the previously opened command prompt and hit Enter:

reg.exe add "HKLM\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device" /f /v TreatAsInternalPort /t REG_MULTI_SZ /d x
Where x corresponds to the Bus Number you noted in step 4.

then reboot and u should be done

just a side note...powershell will work same way as command prompt
