Any help would be highly appreciated big time!!!

Try using below batch (save it as "modfile.cmd").
Note: the space between "%%A" and "%%B" is a tab character. It's not
actually space characters. This is to preserve the original format. DO check
it after copy+pasting the code.

@echo off
setlocal enabledelayedexpansion
if not "%~2" == "" goto chksource
echo usage: modfile {source} {target}
goto :eof

:chksource
if exist %1 goto chkdest
echo Source file not found.
goto :eof

:chkdest
if not exist %2 goto start
echo Destination file is already exist and will be overwritten.
pause

:start
if exist %2 del %2
>%2 rem
set key=SD
for /f "tokens=1,2-4,5,*" %%A in (%1) do (
if not "%%A" == "" (
>>%2 echo %%A %%B %%C %%D %%E_!key! %%F
) else (
>>%2 echo.
)
if !key! == SD (set key=HD) else (set key=SD)
)

@echo off
set X=SH
for /f "tokens=*" %%L in (test.txt) do call :MAIN "%%L"
goto :EOF

:MAIN
set "line=%~1"
set line=%line:~0,63%_%X:~0,1%D %line:~64%
echo/%line%
set X=%X:~1,1%%X:~0,1%
goto :EOF

I do not have time to make the batch but simpler and easier to read
might be:

:XXX
extract line 1 from OldFile.txt and SET _Line="line1"
ECHO %_Line: ADS=_DS ADS% >> NewFile.txt
extract line 1 and SET _Line="line1"
ECHO %_Line: ADS=_HD ADS% >> NewFile.txt
If OldFile is NOT empty GOTO XXX

Here's a version which determines the string to append the string to based upon its character set, i.e the only string containing exactly three alphabetic characters followed by five integers.

::----- START -----
@ECHO OFF
SET "srcFile=test.txt"
SET "dstFile=new.txt"
SET "#=\<[A-Z][A-Z][A-Z][0-9][0-9][0-9][0-9][0-9]\>"
SET "i=1"
(FOR /F "USEBACKQ DELIMS=" %%A IN ("%srcFile%") DO (SET/A i+=1
SET "$=%%A"
FOR %%B IN (%%A) DO ECHO %%B|FINDSTR "%#%">NUL&&SET "_=%%B"
SETLOCAL ENABLEDELAYEDEXPANSION
SET/A i %%=2|FIND "0">NUL&&(CALL ECHO=%%$:!_!=!_!_SD%%
)||CALL ECHO=%%$:!_!=!_!_HD%%
ENDLOCAL))>"%dstFile%"
::------ END ------

Each line has been prepended with two spaces; any line without a two space prefix has wrapped and requires fixing. Those spaces can optionally be removed.
