OT: Windows XP Batch file to set USB Drive Letter

(1/1)

stahta01:
I am experimenting with using Code::Blocks on an USB Drive and decided it is easier to always use the same Drive Letter for some Compilers.

Here's the batch file I use to set the USB Drive to "G:"
I copy the batch file to the root folder on the USB Drive and run it manually when needed.
It is only needed once per computer in my experience.

--- Code: ---@ECHO OFF
REM
REM Change Current USB Drive to be on TARGETDRV Drive Letter.
REM

REM Change to root of Current Drive
CD \

REM Check the current drive is removable.
FOR /F "delims=" %%x IN ('fsutil fsinfo drivetype %CD% ^| FIND /i "removable"') DO SET DF=%%x
IF "%DF%"=="" GOTO ERROR1

echo mountvol %CD% /D > %TEMP%\mountdrv.bat
mountvol %CD% /L >%TEMP%\mountdrv.tmp


setlocal enabledelayedexpansion
SET TARGETDRV=G:
REM Check the TARGETDRV is NOT being used.
FOR /F "delims=" %%x IN ('MOUNTVOL %TARGETDRV% /L') DO SET DF=%%x
IF NOT "%DF%"=="The system cannot find the file specified." GOTO ERROR2

set LINE=mountvol %TARGETDRV%
for /f %%a in (%TEMP%\mountdrv.tmp) do (
set LINE=!LINE!%%a
)
echo %LINE% >> %TEMP%\mountdrv.bat
del /q %TEMP%\mountdrv.tmp
endlocal

REM echo PAUSE >> %TEMP%\mountdrv.bat

type %TEMP%\mountdrv.bat
REM PAUSE
cd /d "%HOMEDRIVE%%HOMEPATH%"
%TEMP%\mountdrv.bat
goto eof

:ERROR1
ECHO Current Drive is not removable.
endlocal
goto eof

:ERROR2
ECHO %TARGETDRV% is already in use.
endlocal
goto eof

:eof
PAUSE

Thanks for sharing!!

In my Windows XP system, the Driver G is already used for a DVD drive. So, this batch file will always give a error message:


--- Quote ---Current Drive is not removable.
Press any key to continue . . .

--- End quote ---

Just set TARGETDRV to the drive you want to use.

--- Code: ---SET TARGETDRV=G:

--- End code ---
