   To determine whether the drive is bitlocker-locked or inaccessible due to   
   other reason, you'll have to check the error message. e.g.   
      
   @echo off   
   setlocal   
   set drive=z   
   if not exist %drive%:\ (   
     echo Drive is not found/connected, or has no drive letter assigned.   
     pause   
     goto :eof   
   )   
   set msg=   
   for /f "delims=" %%A in ('pushd %drive%:\') do set msg=%%A   
   if "%msg%" neq "" (   
     find /i "locked" > nul   
     if errorlevel 1 (   
       echo Drive is not accessible.   
     ) else (   
       echo Drive is bitlocker-locked.   
     )   
     pause   
     goto :eof   
   )   
   popd   
   echo Drive is connected and accessible.   
   pause
