Internal Hard Drive Showing as Removable Disk

In several instances, Windows 10 devices apprehend the internal SSD or SATA drive as a removable one. When users hover over the safe removal icon in the system tray, they come across Internal Hard Drive Showing as Removable Disk. It is very obvious that you cannot eject the hard drive where the operating system is installed. This issue happens in the systems where occurs a conflict between the installed SATA AHCI driver and PC’s motherboard or BIOS. Microsoft clearly clarifies that the problem is with the BIOS itself as it considers whether a device is removable or not. Furthermore, how it positions the various SATA ports on the motherboard also determines the issue. Actually, the inbox driver straightaway examines SATA ports and think that the devices connected to those ports are external, which means removable devices.

So as you can see the problem is with the BIOS, you need to first ensure that it is up to date. Secondly, run a command line that would override how the inbox driver marks the devices in the port as external. Thirdly, try to disable the SATA Hot Plug feature that helped many users. Even if the system tray displays the hard disk as a removable one, try to enable the write caching policy of the hard disk and also modify some registry entries.

reg.exe add “HKLM\SYSTEM\CurrentControlSet\Services\storahci\
Parameters\Device” /f /v TreatAsInternalPort /t REG_MULTI_SZ /d
  • Replace in the above command with the Bus number that you copied earlier.
  • Close all the windows and for an effective result, restart Windows 10 PC.
