Please try the script to safely remove the disk, maybe you will find it useful :)

@echo off
cls

set tempfile="%TEMP%\tmp_disk.dsk"
cd  %SystemRoot%\system32
echo.
echo   ...:: Safely Remove Disk ::...
echo.
echo   Select the disk volume number (if the disk has multiple volumes, select any of them)
echo.
echo.
echo list volume | diskpart | findstr /C:Volume /C:---
echo.
set /p volume="   Selected volume: "
echo.

echo select volume %volume% >>%tempfile%
echo offline disk >>%tempfile%
echo online disk >>%tempfile%

diskpart /s %tempfile% | findstr /C:"not valid"

if "%ERRORLEVEL%"=="1" (
  echo   Disk has been unlocked successfully.  Try to safely remove it now...
  pause
)

del /F %tempfile%
