Batch script to detect CD/DVD-rom drive

REM Check if we have a CDROM drive
Setlocal EnableDelayedExpansion

echo list vol > diskpart.txt
diskpart /s diskpart.txt > dp_volumes.txt
set hascdrom=0
FOR /F "delims=," %%v in (dp_volumes.txt) do (
rem echo %%v
set str1=%%v
rem echo Line is !str1!
rem echo "x!str1:ROM=!"
rem echo "x!str1!"
if not "x!str1:ROM=!"=="x!str1!" set hascdrom=1
rem echo !hascdrom!
)
if "!hascdrom!"=="0" GOTO nocdrom

:cdrom
echo We have a CD/DVD-rom
goto :EOF

:nocdrom
echo No CD/DVD-rom drive available
goto: EOF

Batch-scripting is not as powerful as WSH-scripting or PowerShell.
But with some tools you can perform some simple but useful actions.
One tool I often use is robocopy.

1. Asking for values in a batch-script
   @echo off
@set /P pctocheck=Enter name of pc:
@cscript.exe "script.vbs" %pctocheck%
pause
2. Copy non-existing folders back to C-drive
   @echo off
rem Check if the script was called with parameter RUN
IF "%1"=="RUN" GOTO run
rem Since we are not running the script with parameter RUN, start it using cmd whilst enabling delayed environment variable expansion (/V:ON)
cmd /V:ON /C H:\copy_c-drive.cmd RUN
GOTO :EOF
:run
echo ...Copying extra folders on C-drive
rem List all existing files and directories on the C-drive, including hidden ones.
dir /a:d /b C:\ >C:\WINDOWS\TEMP\rc_existsystemdirs.txt
dir /a:hd /b C:\ >>C:\WINDOWS\TEMP\rc_existsystemdirs.txt
dir /a:-d /b C:\ >C:\WINDOWS\TEMP\rc_existsystemfiles.txt
dir /a:h-d /b C:\ >>C:\WINDOWS\TEMP\rc_existsystemfiles.txt
rem Build up variables
set existingdirs=
FOR /F "delims=," %%i IN (C:\WINDOWS\TEMP\rc_existsystemdirs.txt) do set existingdirs=!existingdirs! /XD "%%i"
set existingfiles=
FOR /F "delims=," %%i IN (C:\WINDOWS\TEMP\rc_existsystemfiles.txt) do set existingfiles=!existingfiles! /XF "%%i"
rem Do the copy thing
robocopy /COPYALL /E X:\ C:\ /TEE /LOG+:C:\WINDOWS\TEMP\rc_system.log /XO /R:1 /W:3 %existingdirs% %existingfiles%
