Hello!
I need to determine whether the DVD device in the computer is DVD Writer or DVD reader
I do it through wmic cdrom where mediatype!='unknown' get mediatype
It returns
MediaType
DVD Writer

However, how can I put "DVD Writer" into variable?

I tried

wmic cdrom where mediatype!='unknown' get mediatype > tmpFile.txt
set /p data=
However the content of %data% is
■MRun this at the the CONSOLE. The variable %mediatype% will have the value DVD Writer

Code: [Select]for /f "TOKENS=* skip=2" %i in ('wmic cdrom where "mediatype!=\"unknown\"" get mediatype') do echo %mediatype%

Good luck.  Please disregard the previous post. When I returned to check it out, it failed. Sorry for any inconvenience. If I find a fix I will post any updated version.

 
OK, lets try Solution 2.0

The variable %mediatype% will have the value DVD Writer

Code: [Select]for /f "tokens=* skip=1" %i in ('wmic cdrom where "mediatype!=\"unknown\"" get mediatype') do if not defined mediatype set mediatype=%i

Good luck. 


Hi 
This how to fix your problem with a BATCH FILE :
The output of WMIC is unicode !
The trailing <CR> can be removed by passing the value through another FOR /F loop.
This also removes the phantom "blank" line (actually a <CR>)
Code: [Select]echo off
set "mediatype="
for /f "skip=1 delims=" %%a in ('wmic cdrom where "mediatype!=\"unknown\"" get mediatype') do (
for /f "delims=" %%b in ("%%a") do if not defined mediatype set "mediatype=%%~nb"
)

echo MediaType is : "%mediatype%"
pauseThe variable %mediatype% will have the value "DVD Writer"
