Hi,
I have written a script to change the OPTICAL drive attached to a COMPUTER to R: drive. Part of the script is as follows:
Code: [Select]::write list of dos devices from registry
ECHO DOS Devices as per Registry: >> %LOGFILE%
ECHO. >> %LOGFILE%
REG QUERY HKLM\SYSTEM\MountedDevices | FINDSTR "DosDevices" >> %LOGFILE%

::loop thru list of dos devices
FOR /F "TOKENS=1,2,3 DELIMS= " %%A IN ('REG QUERY HKLM\SYSTEM\MountedDevices ^| FINDSTR "DosDevices"') DO (
SET RAWRESULT=%%A
SET RESULT=!RAWRESULT:~26,18!

::check devices for optical drives
IF "!RESULT!"=="5C003F003F005C0049" (
SET DLETTER=!RAWRESULT:~12,2!
SET /A CDCOUNT=!CDCOUNT!+1

::set current drive LETTER into variable
IF "!CDCOUNT!"=="1" SET CDROM1=!DLETTER!
)
)

After this has been processed, I want this to happen:
If the CDCOUNT variable is equal to 1, keep going.
If the CDCOUNT is not equal to 1 do the FOLLOWING:

• "echo ERROR OPTICAL DRIVE COUNT NOT EQUAL TO 1" to command line
• "echo ERROR OPTICAL DRIVE COUNT NOT EQUAL TO 1" >> %LOGFILE%
• "echo OPTICAL DRIVE COUNT: echo %CDCOUNT% >> %LOGFILE%
• "GOTO END"
